Roland SP-606

As soon as I got it, I gave it the once-over and recorded a few samples, which were easily assigned to pads and could be thoroughly modified with fairly straightforward sample modding tools and your standard, fairly decent effects processing. It's simple to record your manual playback of these samples and to create patterns and songs based on them. The manual covers these abilities and then just sorta dies out. No mention is made of the on-board sequencer at all. When it comes to importing .wav files from your computer to your not-supplied Compact Flash card, the process is very cumbersome and annoying, but it will work. Too bad the weak processor is too busy flashing pointless lights to properly play your samples back without hurking and jerking. I downloaded the firmware update and installed it easily. No better.
The Cakewalk P606 software is a joke as far as actually loading samples and patterns to the unit. It's just a cheesy Fruity Loops-type application which only will function with the SP606 plugged in, making it completely worthless except to someone with a laptop who wants to convince gullible people that he has something to do with the patterns being played.

Poor polyphony, bogs after 4 stereo samples. Effects are simple to use, not too powerful, but whiggy enough for most applications. D-beam controller is a nice feature for DJ-types or freaks. Pads are too small for my liking and due to the unit's limitations, have a very shaky feel as far as actual connection to the sounds you hear. It's choppy when you aren't really asking much of it. Sequencer is crappy as hell and unsupported by the manual. It does work, but you're on your own.

It's a sampler, pads could be better, effects are okay.

I'm actually hoping it catches on fire. NOT RECOMMENDED.

They have regional facilities which perform upgrades and might repair the things which break, but they can't seem to provide that most basic support of all, an actual manual. It comes with a small booklet which is primarily concerned with the things you don't need to know, such as not to immerse your SP606 in water and what the volume knob does, but is amazingly INCOMPLETE when it comes to actual instructions for many of the unit's primary functions. Totally unprofessional.

I was hoping to use the SP606 as a sample module for my digital drum-kit. I had some live shows to do and had become reliant on the killer drum kits I trigger on my PC. They're just .wav samples of effected and clean drum sounds. I figured this unit could easily fit the bill. After the laborious task of loading the samples to the Compact Flash card and then assigning them to pads and balancing volumes, I discovered that the processor is too weak to keep up with anything other than fairly sparse playing. The drum samples aren't lengthy at all, but the SP606 just can't keep up. I can plug my MIDI cord into any of my synths and dial in some kind of decent sounds for percussion, but this thing just won't do it.
For live DJs, it might perform as a needlessly expensive, mini light show which on the side does a fair job of doing simple sampling. For anyone expecting any sort of real value for price and/or true functionality, it is NOT RECOMMENDED.

This unit is really easy to use. I mean, if you can use fruity loops you can use this box.

The presets are crap, of course. But WHY oh WHY do people still want to use presets????????????? Presets exist so that the discerning listener can tell when a bozo has been at the controls!

Haven't used the onvoard editing facilities - no need as you can simply use sound forge and import the files back across.

Manual is really easy to understand. Good to see they finally have someone who speaks engrish writing their manuals.

Polyphony is only 8. But this isn't a prblem as you can always bounce complex rythms back down to just one track (voice).

Some people seem to be complaining that the use of stereo samples reduces this to 4. True - but why would you be using stereo samples in a club when ALL clubs (that I have come across anyway)are wired in mono????????? This is a performance instrument. period. You want a studio sampler get something else. You wanna perform on stage get this.

The pads are really expressive, heaps better than the MPC, nearly as good as the old Yamaha RY's.

BPM is linked to the pattern you are playing - so make sure your patterns are as quick as you want before going on stage. Having said that, there is no problem changing the BPM on the fly - the unit keeps up and brings the other machines along with it (I have it running with both an MC505 and an MC303 as slaves).

Effects are absolutely awesome. If you want something different than all the SOFTWARE crap out there the fx on this machine are for you..

This machine is a TECHNO box. Tech, trance, house etc, this machine is the bollocks. Hip hop, DnB, Breaks etc, MPC still probably a better choice... However, the 'recycle - like' function of the breaks chopper could be inspirational for those types of music..... I dunno, as hard techno/hard trance is my bag.

The fx are simply great. Plus two independent fx processors means you have enormous creatice potential, right there in the bow. Plus, it has a third fx processor just for compression. Awesome, a company that knows we are making DANCE music!!!!!!!!

This box is absolutely dependable in a live situation. I always rely on it and it has never let me down.

haven't needed it.

This box rocks. It has it's own sound, heaps different (and better) than all the obviously software created pap that's around these days. It's quirky, and it takes a little time to really get the most out of it. I would never be without it.

Using it with the bundled software is a dream - easiest way of coming up with original patterns I have seen in 15 years of creating electronic music.

Only thing I would really like to be different is the abilty to change compact flash cards during a performance. As it stands, you have to turn off the machine to swap cards. WTF?

Well, it's a mixed bag with this thing.
Almost all of the needed functions have dedicated buttons, or moreso, are clearly printed under other buttons and accessible by the SHIFT key. Several compaints; As presets are worthless, it was hard to dig up how to "un-protect" them so I could trash them. Also, this thing has dedicated buttons to switch whether the samples/beats are being controlled internally or externally. That's NOT something you're going to change on the fly (or even from night to night), so that front-panel dedicated-button space could have been used for something much more useful, such as a dedicated tap button. Speaking of tap, you have to open up the BPM sub-menu to start inputting tap; really disrupts flow. The list of design flubs goes on.

Let me put it this way, This thing is rather easy to use if you you're going to use it JUST as a more powerful (longer memory, more effects) version of the sp303 (because there are some -505 features this thing drops the ball on) to stop and start audio samples w/ buttons. Likewise, to a lesser degree, it works if you want to use it as a pattern sequencer to whip up a SINGLE BEAT (more on that later) like an MPC (but it still gets outclassed by even the mpc1000 in terms of midi range). Due to it's limited polyphony (4 ?!?) and processor allocation, this thing will VERY quickly falter if you try to play synced-sampes on the fly over pre-sequenced patterns.
This thing may look like it was built to do JUST that combination of things in the store, but I guarentee roland paid some guy to tweak the factory samples/patterns to get the most "apparent" mileage out of this thing w/out having it falter.

quite simply, the Sp606 is the idiot-savante of groove-box samplers.
...allow me to explain...
The sp606 has a pretty powerful sampler, and it's the first hardware sampler I know that can really convincingly stretch a loop to fit arbitrary tempo sync (w/in a certain range). Software has been doing this for a while (ableton, acid), and on akai and yamaha samplers, you have to stop and edit samples and tune/stretch them to a certain tempo. This thing, you can import a sample, assign it as a "prase", turn on "tempo sync," play the sample, and it will stay in sync while you change tempo, even via external midi clock.
The only hardware that did this before was Variphrase technology
(...a really incredible innovation that they haven't taken taken anywhere else).
In terms of "hey let's automatically sync up these various groove" the 606 manages a pretty impressive partial-showcase of variphrase ideology.
That IS impressive, and that's mostly why I bought it. Specifically, you can designate samples to identify as any number of beats (1-7) and measures (1-8 or so). Well, I make indian music w/ poly-metrics, so I throught it would be really cool to have samples of different beat patterns play against each other IN SYNC (thus creating a hemiola loop); i.e. a 3-beat bassline sample and a 4-beat sample drum sample both play at 120 bpm and hit a common "1" every 12 (4x3) quarter-notes.
And this sp606 can do THAT w/ two samples. This really impressed me in the store. ...took it home, found that the sync really starts falling apart if I taxed the processor w/ a 3rd odd-sync element.

Ok, so I figure sequence-playback would be less processor-taxing than realtime-audio-stretching. The other reasong that I bought it is that it has a built in pattern-sequencer, so I figured it could not only replace some drum machines, but it could work as a master-clock for my (more-simple minded) electribes.
WRONG.
Not only did I quickly become frustrated w/ the paucity of polyphony, but I quickly found one of the poOorest design flaws I'd ever seen in a "groove" product of any brand.
Let's see, a groove product is supposed to "keep a groove," right. you start it up, rock along to the beat, and maybe jump around different patterns at that groove. Mechanically, this can happen because, in terms of processing heirarchy, the tempo/clock element is ABOVE the sequencer information.
Well, in the sp606, each pattern has a "native" tempo that if forces the machine to play at. Worse yet, that "native" tempo is determined by whatever tempo that pattern was last played at.
REAL LIFE EXAMPLE.
out of box, the "Hip Hop" patterns (1-10 or so) are all programmed at 90 bpm. so you can leave this playing and mump around all this "hip-hop" patterns, and never interrupt the hip-hop groove. Fine; that's enough to to impress some people to buy it. But, the "El House" series of patterns all come set to 130bpm.
If you're grooving along a "hip hop" patch at 90bpm and fly over to to a "house" beat just to change the "feel" well, this "groove workstation" hiccups and forces a tempo change.
Worse than that, let me explain about how "native tempo" is "last tempo" say you're grooving on the "hip hop" beats, find one you like, but need to slow it down. when you're done, Now that beat got parked at a slower tempo, so now all the "hip hop" family won't match up.

WHAT. THE. HELL.
this is a $640 "groove box," you think it would be able to keep a "groove" w/out completely tripping over itself.
I called roland customer support. they said; "well, it will play any/all patterns at a fixed tempo when slaved to another devices midi clock." I got news for you, Roland. If I pay that much money for a "groove box" which a Roland product field-rep himself (Philadelphia area) tells me will happily replace my lesser- groovebozes (electribes) and samplers (ps-303), I expect it to be able to function as a midi master clock.
this is a six-hundred-starving-forty-dollar groove machine, and INTERNAL clock is NOT a GLOBAL and persistent function.

...Don't even get me started on the "p606" software for which you use the SP unit as a "controller"...
I just don't even want to talk about it.

Someone below mentiones you can dump samples to your computer via usb. Never figured it out. Boo!

as a sampler, it's garbage-in-garbage-out.
out-of-box, the factory samples are garbage.
When will roland learn to stop making samples of that white sista's voice going "come-on," "baby," and "doo-doo." what do they think this is, '97? How much do they pay that bitch? Get her off my sampler.

Also, as menionted below, the effeects sound great, and the d-beam synth and filter are fun.
Unfortunately, you cannot save the effect settings (like the sp808) or even have them come back as you left them (like the sp303 does). Also, while you can program the d-beam to make a wide variety of synth sounds, you cannot save "synth" patches (like the sp808).
If this thing can juggle rom enough to beat-sync two samples from differnt tempo's AND meters, why can't it remember a handful of patches.
Totally UNinspired and non-conducive to expressive creativity.

Every time I've tried to change pattern, it's changes tempo. Without fail, it disrupts the groove. It is un-useable for live groove-work 100% of the time. I can depend on it to
I will gig without it, because I'm going back to my "backup" electribes.

I am absolutely stunned that nobody else has mentioned this. It is probably because, understandably, people are just using it as a big-fat-303.
if that's the case, save your money, buy the shiny new 404 w/ the hip blue lights.
whoopee.

Hey roland, it's great that you FINALLY caught the boat on publishing your manuals online.

Some guy below lists a bunch of gripes, and then says "but I'll hang onto it," because maybe he'll "never be happy."
That's just not the case for me.
I've spent 9 weeks trying to make this thing work for me; used internal and external midi, tried all different approaches. While it's time-stretching is truly savante-genius, it's a really Idiotic and incompetent "groove" candidate.

Truly, an idiot-savante groove sampler.

Roland, if you're listening; Make a rack sampler that can do all the phrase-tempo-matching TIME (of different meters) that the 606 can do, and make it capable of sampling on the fly, w/ auto trim (you already made "ext seq sampling").
Make it capable of storing a bunch of my favorite loops and such in the ever-less-expensive flash card format.

Make it capable of playing samples as "phrases," "loops" or just "drum hits". And maybe build in a simple (master-clock-complient) 4 track sequencer.
Basically, build up the 606/variphrase technolgy into something that can replace the live LOOP SYNC market that is STILL being dominated by the Electrix Repeater (which got it right the first time much more than you guys ever did).

seriously, I'm starting to believe I could have done better.

I use this for live performance and rarely if ever rely on the sequencer. I program my own home-grown sample loops and upload the 4-32 bar stereo .AIF loops I create on my Apple computer with Cubase to the sampler for use live. Keep that in mind as you read this.

I'm using the latest OS, as far as I can tell, but I'm hoping there's a useful update coming along that would eliminate the VARIOUS glitches and bugs I've noticed so far. Those being:

1. SIGNIFICANT lag time if you're playing multiple stereo samples (nearing the max polyphony) and need to switch pad banks/switch effects on the fly or live. This is a $650 sampler! You can get a laptop that would respond better than this for less!

2. You can use a 512mb card with it, and it can hold 512 samples, but IF YOU USE STEREO SOUNDS, YOU CAN ONLY IMPORT *100* FILES FROM THE CARD UNLIKE WHAT THE MANUAL SAYS (the manual states it will recognize 200 files. I guess stereo files count as two). So boasting that it can hold up to 512mb of sounds or over 3hrs of music is a bit of a wash, considering you'll be triggering one long-ass sample if you do that. And don't forget my first complaint if you DO decide to max out the pad banks.

3. The USB uplink can store samples from your computer. But at the speed of USB 1.0??? It took me over an hour to load up my smartmedia card the first time through the sampler with 200 stereo breakbeats I made...only to find out that half were missing from the "File Import" command and not usable. Not only that but the "File Import" command that assigns sound files to the pads in the pad bank takes FOREVER. Put aside about 20mins per bank for "Processing..." and a cute light show on the pad bank area my cat Boo Boo obsessively plays with. If you think you can use multiple cards and load them up fast for a live environment, you are WRONG.

4. DON'T MAX OUT THE SAMPLER'S MEMORY (first 8 banks)!!! You'll get a "MEMORY FULL" message and you won't be able to use any other banks or essentially do anything until you right the error of your ways. YES, you WON'T be able to put files on banks 9-32 if the machine's memory is full first! And this is still subject to my first complaint above.

About the presets: Straight to the trash. I don't use the sequencer either as I use this to trigger loops live by hand rather than recording it. I won't edit sounds on this thing as it looks like a button pushing nightmare to do. The included software package is a cruel joke if you're a Mac user like me, as they didn't bother to make it dual platform. From what I've heard though we Apple users aren't missing anything.

The manual - well another gripe of mine. I would rather have the manual be LONGER and more IN-DEPTH in .PDF format than have to go through that much redundancy and vagueness again in paper format. Also having a paper manual pushes the cost of the unit up for the consumer.

Oh man the polyphony and lag issue. I'd always like more polyphony. :)

The effects on this thing are stellar. Weird things can happen if you mess with them enough. Great live. Unfortunately a few of them cut the audio out completely if you turn the value knobs - like moving the first knob back and forth using the Lo-Fi Processor effect. Super annoying.

The smartmedia cards do a good job as an add-on. I wouldn't advise relying on the built-in memory on this thing. Better to have too much memory than not enough.

For as much complaining as I've done, this unit does the work of many pieces of gear (onboard synth/d-beam/filter, 2 effects at once, sampling/resampling, cd quality stereo sound) and makes me look like a theremin using magician on stage for a very small piece of real estate. It brings the sounds I make in the studio to the live presentation, which is EXACTLY what I was looking for.

The d-beam filter setting is WAAAAAY too steep. One millimeter can kill the sound at times! However the Synth d-beam setting is S-I-C-K. Especially for live performance.

I'm not afraid to say that even with the limitations I've mentioned this will be a piece of gear I use at gigs for YEARS.

Yes, I can depend on this with my life. Made of metal, sturdy. It's a good piece of gear that requires some tinkering to know the ins and outs of but once you know the limitations you can work around them quite easily. Just don't get stuck needing to your next pad bank ASAP, or you'll be in trouble.

I thought it was my Holy Grail, but it will do for now. It is irreplacable live in my opinion though. For what I do when I perform, this is what I wanted. I guess maybe I'm just never satisfied.

If I get famous, I'll force the company to come out with a model in my name that would eliminate the bugs I mentioned.

it is really easy to use, the preset patches are ok if you are in to the hip hop stuff, if you are not (like me) the best is to create new pacthes.

easy to record, easy to play.

you will not need the manual to figure out how it works

it does everything it says it does. sampling, effects, resampling, secuencer, i think is the best of this kind of gear.
but
there are features that are necesary:
- sampling and resampling on the fly, you'll have to stop playing if you want to reasample something
- capability of using 3 or more effects at the same time
- more knobs to control things on real time

the "beam" control is great but you can only use one kind of effect with it

it tounds like the sounds that you sample.
the output is kind of low.
i use basically for life remixing and it work well, but you need to be really precise, if you misstouch a button you'll probably cause the thing to stop playing.

i'll need more control over it, knobs and buttons, rather than the LCD menu.

you can take this gear to a gig it will not crash.
and that is really good.
you can control your computer with it, midi, and some software that it came with. that is really useful, because you can control conputer and sampler from the same devise at the same time.
but
you can not resample in realtime.

N/A

it is a really great gear, but we (musicians) are always asking for more, and on the fly resampling and secuencing is what this needs. i've been playing with it for like 4 months and it is working well. after the 1rt week you will start finding the limits of this gear, which are not many but important.
i don't like the way the design it, it doesn't look so good.
it would be great to incorporate like a Kaoss Pad in it.

Updated recently to 1.05. Was not that easy to find, but updating the machine was a breeze. The presets are good to get you going and to experiment with the built in fx, but you after playing around with them for a hour, you will want to record your own stuff. You got a lot of possibilities to get your own samples on this one and the option I prefer is via USB. It's as easy as 1,2,3. The Sequencer is o.k. Its a pain in the ass to program full patterns from scratch and there is no way to copy events or even import presets from your computer... My major concern in that area. The manual is nice, needed it a few times when I unpacked the thing. The really important sections are too short. The card pad banks start at 9 by the way. Nowhere mentioned.
Every function is callable by pressing one or two buttons, that's really nice.
And the support of compact flash cards is a big plus. But had to update to 1.05, because my 512MB card was not recognized correctly with 1.03 firmware. Be sure to download it, if you want to use bigger cards.

The complete interface feels solid and is well built. Good to play and reliable.
Okay, polyphony. Its got 8 note polyphony which are consumed way too fast. But the biggest issue that I have is, that if max. poly is reached, the sample first played will be muted. For example: You want to playback a complete track (song) via pad and play additional sounds from other pads to it (not using the sequenzer). Should be fine as long as you watch your polyphony. If you exceed it, the song (as your first sample) will stop! You can imagine what it is like on stage...
The real bad thing about this is, that you are not able to tweak how polyphony is handled (eg. no new sound will play unless new notes are available).
The sequencer is 4-Track, but taking a look on the polyphony you will never need more.
Read above for my major laments about the sequencer. A nice feature though is, that you can live record your play and don't have to stick twiddling in micro-edit. Measurement is bar oriented like on software sequencers which is nice to have, too.
MIDI IN and OUT, no THRU. I rarely connect more than 2 devices, so this is o.k. for me. Midi setup is easy and works nice. Though I didn't figure out how to start the playback on computer via the sampler (other way round works fine).
The effects are easily accessed and easy to tweak. A lot of fun. You can use 2 at a time, which is a little restrictive, but o.k. I have a kaoss-pad 2 ready for additional mayhem, if needed.
I use the built in D-Beam-thingie frequently, but only find use for the filter option. But you have to get used to its handling. Don't use it after drinking lots of whiskey ;-). The filter of the beam is nice, though.
It's got lit pads and a big background-lit LCD, which is a big plus on stage.

Sound is what you make of it. The onboard sounds are nice and well mixed. I like them, though I always run many effects through them. I use this thing for creating industrial stuff and for live play. The effects are cool. I actually never tested them all (there are about 40), but I really like the filters and the guitar amp. The distortion is a little bit disapointing, though. Jamming around with this unit is a lot of fun. I don't like the aftertouch of the pads, so I edited them to be static. Ok for me. Sounds crystal-clear in my ears. Output is low, so you have to amp it a little.

I will have a concert soon and I will take it with me. I'm damn sure it can take the test. No backup required. The flash card sticks like glued in this unit, this would have been my only concern. It's built of plastic, but it's quite sturdy. Be sure to get a metal-case for it and keep it dry!

Never dealt with them except for the upgrade. Had to search the US-site for the upgrade, but finally found it. The upgrade information contained with the firmware was detailed and guided me well through the whole process. The german site seems a little bit out-dated, though this unit was sold in europe first and it has been for sale for a quite few months now... ROLAND! WAKE UP!

Own this piece about 14 days now. Never learned to use new gear that fast, which is cool. I like it. I will use it preferrably for live-action and will improve my performance a lot. It's so easy to use. When I first unpacked it, I jammed a whole night just using the presets and the fx without having to peek into the manual and had a lot of fun. If the sequencer was a little more comforable to tweak, it would have been perfect. The usb-connectivity and the flash card options are great. I like the filters. Built-in fx are cool. I tested the P606-Software, but didn't care too much about it.
There is no better sampler available at present in that price range, so this was my pick. And I don't regret it, though the sequencer really lacks use and the polyphony... Well, I just won't talk about it no more...

The presets are standard hiphop/house/R&B type safe samples. However you can of course get rid of them all and put what you want in. Editing patches is fairly straightforward there are only a few parameters. The one glaring omission for me is "normalise".
I will be editing samples on my PC and trasnfering them to the sp-606 so it is not too big a problem.

Polyphony is 8 mono, 4 stereo- depends what you need as to whether this is limiting or not. The touch sensitive pads are expressive and light up when played which is a good visual cue as to what is playing when. The effects section is good- 2 multieffects units which can be tweaked in realtime with the 3 controller knobs. there are 45 effect Algorithm, all the usual suspects plus some nice bpm synched stuff (tremolo, pan for example). The SP-606 uses compact flash cards up to 512mb. A big plus is that it streams directly off the card giving access to large samples immediately. I am using mine for live work with mainly loops so this is ideal. easy for transfer and none volatile. MIDI in and out. Digital in and out (Coax type) as well as analogue in/out. It is also USB enabled so can act as both a midi and audio interface on a PC. The flash card can be mounted as a drive in windows to tranfer files but I found it quicker to use my USB2 card reader. It has 25 song and 140 pattern memory. 4-track basic sequencer- again all I need but some may find this limiting.

Samples are as expressive as you make them. Qualitywise it sounds very good to my ears. It is fairly easy to use. There aren't too many submenus or multiple button pushes required. I think it is suited to any style of music based on what samples you use, you can loop samples or have them as one shots and it can read acidised files for loop points etc. There is a D-beam controller which can be used to trigger samples, control effects/filtersweeps etc and also trigger a basic monophonic synth. The first two are useful, I am not sure about the synth.

It feels sturdy enough, I would trust it to gig with. a nice touch is that it comes with a screw on metal plate to stop anyone removing the flash card, useful for gigs.

No need to use support as yet.

I would get another if lost as it suits my needs well. I am predominantly a guitar player and have started playing with a new band which uses samples, a bit of a departure for me. I find it intuitive to use and I like the cakewalk software that comes with it (p606). This is basically a pattern based multitrack sequencer with intruments, effects and loops. The interface between the two is fast and accessible for laying down quick tracks and ideas-these can then be sampled directly into the SP-606 with perfect beat precision for use live, it can of course be used as a control surface for any audio software.

rom version 1.03
the presets are pretty awful, but it's a sampler so forget about presets. editing sounds is easy because there is not much to edit. it can play phrases, loop them and that's it. there's not even a normalize function. the sp-505 had it, why didn't they implement this on the 606?
but basically it's easy to use and that's what i bought it for.

polyphony is weak. only 8. stereo sounds take 2 voices. the "keyboard" is good, velocity sensitive. i guess the fantom has the same. the built in effects are the second reason why i bought it. i has quite a lot of experimental effects (or effects to use in experimental music, that's what i do). and you have two of them which you can use in serial. a very good thing is also, that it uses CF-Cards for storage. and you can play samples directly from the card. 512mb max! the sequencer is not very good (only four tracks) and what i really hate about the sp-505 and the sp-606 as well is that you cannot resample sequences. when resampling you cannot use the sequencer.
you can use it as a usb-soundcard for your computer. they also include a program that you can control with the sp-606 but i don't need it.

it's a sampler so it depends what sounds you record. sound quality is ok but not great. output level is quite low.

i will gig with it for sure. but i just bought it today.

don't know.

i own quite a lot of gear so i only bought it for performing live with a microfone with effects and a few samples.
i compared it with the korg esx which is much better with sampling, resampling sequencing but has much les effect algorithms and less suitable for my needs.
