Sequential Circuits Pro-One

Very good as soon as you learn the modulation part. Especially for live-interaction. You can choose from Direct-modulation to Wheel-modulation. Control it from a seqeuncer switch between the different modes and strange sounds will appear

Great inspirating sequencer that is very easy to use. No poly but if you tune the filter together with the oscs for chords. Audio in that is very useful. Try but a guitar in, tweek the resonance, Osc-B modulation on the filter and go nuts. Very good with external (V) filtercontrol-jack.

I've had som problems with mine because sometimes the keyboard stops to function on the upper octave. Otherwise I like the keybord. It bounce back in a nice way as you play. The sound are as fat as you want them. It's not as smooth as the moog but it's very hard and acidy but also special and genuin.

Yes
Yes. I had mine flown around on a tour for 1 month. It worked perfect (excpet the keyboard every 10th day). I didn't had to tune every night actually. It is very stable.

It's definitly worth every SEK.
It is one of the best synths i ever have tried. Its cool and unique and with the simple seq onboard you can create very direct and and beutiful sounds: OSC: triangle(high pitch)
VCF: high env-mod,resonance and low cutoff (short decay)
SEQ:Long sequence of random majorscale notes, portamento, ruin it thru a delay-unit and you are out there...

If you're already comfortable with ADSR analog stuff, then this thing shouldn't be too big a deal, but it's probably not for beginners or the easily confused. Otherwise, it's got lots of knobs everywhere, whee!

Monophonic, of course. The keyboard action is crap. It's the worst I've ever played. No effects, no expansion (I guess you can retrofit it for MIDI, but mine isn't), no MIDI, it's got a fun little on-board sequencer, but I don't use it. It's analog, whaddya want. I give it a ten for manipulative power (two oscillators, baby).

It's got a nice bite to it, and it's seriously flexible. I think it has a "sharper" (will that make sense to people? probably not) sound than the Mini, which is maybe a little warmer. I love it. I seem to use it mostly for basses. I know people are going to read this and look for Moog comparisons or something, but I think they sound sufficiently different that the hardcore analogist will want one of both. At least I do.

Um. Well, mine sits in my studio. I've never had to do anything more than calibrate and tune it. I don't think I'd gig with this, though in this day and age, if you want to gig with analogy stuff, get a Nord Lead or something, I guess. Watch out for those keys, I'd say.

I guess if it were lost or stolen, I might not get it again, but that is only because it would be an excuse to buy something different. If I lost it, I would cry for weeks. I'd miss it more than my left hand. It is easily worth what I paid, especially since a quick check on most lists seem to sell this for $150 more than I paid for it.

Well, it is , of course, monophonic, but it has highly elaborated cross-modulation possibilities that can make it sound like it had more voices, no joke! Twiddling the knobs till you get your favorite sounds is incomparible fun. Maybe the MS20 comes close to this, but the Pro One is not modular system orientated. Through the knobs on the front panel (and there are a lot of them, not mentioning the switches) you get acces to all parameters at once and nothing like plugging cables gets in your way while tweaking this tough little unit till your bass-chassis will pop out of your speakers.

VCO A has got saw or pulse. VCO B has the same but can also produce triangle. And there is a really harsh noise generator with an own knob. The LFO and the VCF section is like would expect. the VCA has also ADSR. On the left side of the front panel are three knobs: VCO B, the filter and LFO can modulate VCO A or B frequencies or pulse widths, and the VCF. These modualtions can be combined and controlled via the modulation wheel or directly put to the target you want to modulate. The keyboard action is soft, a little bit slow, but accurate. There is also a switch for first or last note priority. And there is an arpeggiator with a simple up and down mechanicism. But if you try it out combining it with the record option, it also as a 20 step sequencer onboard you will get unbelievable results. Maybe you will need more than ten fingers sometimes but thats your problem. The 20 step sequencer of course cannot be stored. I forgor to mention that this unit has none memory. If you play only 19 steps the data will be lost. If you play 21 notes the effect is the same, so you should refer to count while playing. No Midi but CV in for filter, so if you want to use it in a midi-chain you can get any Midi to CV converter (eg. Doepfer MCV 4) and can control the cutoff frequency from your masterkeyboard.

You can do punchy Moog Basses, weird 60ies SF-effects like UFO takeoffs or touchdowns. Acid is the second name of it but also creeping soft basses and bassdrum sounds are not strange to the Pro One. The Pro One impersonates exactly one voice of his big brother, the P5. I already heard Snare sounds, trumpets, whatever you like. If you are looking for a modular sounding bassmonster this is for you. It definitely plays in the same league like the Minimoog or SH 101.

If you let it warm up for at least one hour the VCOs will stay pretty stable, an exception for those old guys. You can take it out for a gig, sure, but I keep mine in the studio for it is a little treasure. It is one of Vince Clarkes favourits, enough said.

There is a small company here in Vienna which is specialised on repairing analogue gear, so this would be no problem. The company itself doesnt exist anymore, long gone but never forgotten.

I would buy it again and again and... If this would be my only synth I would hook it up with a drummachine and up we go. Indeed I did some tracks only with the Pro One and a HR 16B drummachine. If you like synthpop this setup enables you to compose not only basic tunes and harmonics, but build up a speedy trance and really whirling acid when you turn on the knobs while being triggered via midi. What more can you want?

Great analog monophonic synth. Lots of knobs for easy tweeking of sound. Switches a little on the clumsy side though.

One note polyphony. The keyboard sucks. It's action is like unlubricated penetration. No built in effects except a external in for another audio source. CV i/o and internal sequencer is handy. Works much like the sequencer for an Roland Sh101. If you have some old Roland drum machines like I do, you can use the trigger out from the DM and into the Pro One's trigger in and sync the sequencer to your midi clock via you drum machine.

Like almost any analog synth. It can be as expressive as the programmer can make the machine communicate his expressions. This thing is great for what ever types of creative music you do. No velocity or aftertouch on this thing. It's premidi baby!

Rely on it, thats a bad question. Mine blew up the other day. I have 4 friends with busted Pro Ones at the moment. Parts aren't easy to find on these puppies. I've found another machine to replace my broken unit but I'm keeping the broken one for parts. It's made out of wood and plastic.

They don't do jack these days...I have a local guy who fixes my shit.

It's a great sounding synth. Near one of a kind. Don't be suprised if it breaks on ya after you buy it. I love the thing but I'm kinda hating it right know cause it's useless to me till I can get a replacement. If you're buying analog remeber it's like buying a used car with possibly lots of miles on it. Inevitibly will need some fixin' at some point. Since it's broken and nearly unfixable and I love the box so much, Yes I am going to buy it again.

Very easy, very versatile. A joy to screw around with. All of the modulation switches can get a little tiresome and confusing, but that's minor.

Monophonic, no MIDI, no effects, the keyboard sucks. Great glide, arpeggiator and sequencer. Audio and CV in.

THe best. Short of a Mini Moog, this is THE one. Excellent sound, totally versatile.

The keyboard sucks and is constantly giving me problems at gigs, but otherwise, everything else is ok.

?

The best value for the money. I'd buy it again and again, but the prices are going up and up. Beats the heel out of a Moog Rogue.
