Blue Chip Baby B

This is a half-rack version of Blue Chip's OX7, supposedly they have the same tone generation only the controls are different. The factory presets are awful. Setting it up to make decent sounds is impossible without computer MIDI input. However, once the machine is set up, it's fairly easy to use. You can find the drawbars easily on a dark stage, and it accepts enough MIDI from a controller keyboard to make things easy, good for live use.
Manual has enough information to get by, but is not very good. It's badly translated, and it's a chopped down version of the OX7 manual, and some controls mentioned in the manual are not on this instrument. Manual describes how to use sysex for patch editing, but not very well; for example, rotor sound tweaking is possible for length and radius (??) but no definition of length & radius is given. Still not sure what these are, if they're mic placement settings or leslie type settings or what. One major thing is some sysex commands cause the unit to be silent; I think they were misprinted in the manual. Also, for setting vibrato to chorus, have to set 'celeste' not 'chorus'.
From unpacking to ready for stage use, it took me about 9 hours to get it programmed and ready for use. I'm a sound tweaker and not very good with sysex, though; someone else might be able to get it ready in 2-3 hours.

This is a dedicated organ half-rack module, capable of reproducing hammond B3 and H100 tones, as well as Wersi or Galaxis organ sounds. Nicest thing about it is the 9 sliders to use as drawbars for real-time sound changes, without having a separate drawbar module to take up extra space. Drawbars don't have click stops, you have to guesstimate them; the response isn't the same as a B3 (stop 4 is 3/4 down, not half), but they're still useful once you get used to them. Can set them up to either push up or pull down for changing sound.
It has a Leslie emulator, reverb, percussion (2nd, 3rd, user), and overdrive. Some minor editing is possible from the front panel, but don't try to do it in a hurry. Real patch editing possible only through sysex; a lot of things can be edited.
The unit is three-voice multitimbral; designed to respond to upper manual, lower manual, and pedal bank. The drawbars can be set to control any of these manuals from the front panel. Takes a dedicated footswitch (1 or 2-button, for fast/slow and brake commands) for leslie control, or you can assign a MIDI controller to it.
There are some control issues, at least with my keyboard controller. Response to sustain pedal input is weird; lengthens notes but does not sustain them. Overdrive is mapped to mod wheel. You can turn off all controller responses to avoid accidental changes; can also set it to turn off if a certain program change is received.
It can transmit the fader movements from drawbars as MIDI CC messages, if you want to use the drawbars to control something else.

B3/H100 sounds: decent. Better than some modules, and drawbars make it better than a preset box. Foldback isn't quite right, and percussion doesn't rob the drawbars right, but unless you're playing for organ fanatics it's hard to notice. On its own, the sounds are great for jazz or old-time organ sounds. If you're looking for rock/blues sounds, you'll need something else to run the tone through.
I don't use Wersi/Galaxis sounds from this; they sound like the cheesy organs you used to see in mall music shops all the time. Maybe someone needs this, but not me. Chorus/vibrato are pretty good, and can be set along with percussion specific to each patch. Sysex editing allows enough tweaking to get good sounds out of it, but again the factory presets are awful. Best feature again is drawbars in a compact unit, this is why I bought the thing.

Leslie: Leslie is okay, but not great. It's very clean and smooth, not exactly what I wanted. Supports fast/slow/brake with a footswitch input. I don't use the onboard leslie, I run this unit through a Digitech RPM-1 for leslie and overdrive, since most of the stuff I play is rock/blues where I like a growly wheezy organ tone. Some might like it, some won't, this one's pretty subjective.

Overdrive: Garbage. Mixing white noise with the organ tone. Use something else for overdrive.

I've only had this a few months, but haven't had trouble yet.
It was beat up when I got it, still works fine. Wall wart power is an unusual AC voltage, might have trouble finding a replacement when it dies (all wall warts die). Does not run hot. It's survived a few gigs unscathed, I think it'll last a few years.

Never dealt with them. Only one US distributor, I don't expect to get support if I need it.

As an organ module, it's decent. Drawbars on the face are the best part. The organ emulation is not as good as the Hammond modules. I haven't heard a Voce V5, so can't compare that. The OX7 which supposedly has the same sound architecture was part of a B3 organ shootout some time ago, you can find the results on the net. Organ professionals gave it poor marks compared to Voce, Korg, Roland, Hammond organ modules & keyboards. I think it's okay, at least for local band use. It's a compact organ module that fits well in a stage midi rack, not the best for studio work or dedicated organ gigs but good for a mixed keyboard gig where you need good organ sounds and drawbar control on some tunes. Definitely needs a better overdrive, and since there's no effects loop that means a separate overdrive and leslie.
The list for this unit is $895; it was never worth this, as you can get other, better modules for near that price. Used, it fit my budget and needs. I play keys in a mixed rock orginal/cover band and a blues band, and this works pretty well. I'd buy another one around the same price if I lost this one.
