I know it's not readily available (or at all), but I was tired of having scattered around information all over this site, trying to read up on the Bubble Chamber.
Now we have a place! LFO -speed knob
---random steps (like the old sample+hold filter sound, robotalk, seek-wah, type stuff) -multiplier knob:
sets the relationship between taps and the speed of the LFO. This lets you tap on the quarter notes and get an LFO that is 4 times faster but still beat locked. Possible settings:
---double time triplets
---quadruple time -Wave distortion knob:
This lets you contort each waveform in interesting ways, and works differently on each wave. Lets you set duty cycle on the square wave, changes the spacing and "hardness" of each waveform Filter section:
-envelope up/down sweep switch
-2-pole/4-pole switch Pitch-tracking LFO:
speeds up when you play a high note, slows down on low notes. Pitch-tracking LFO is separate from the main LFO, so you can have both happening simultaneously if you want max madness. -pitch track knob:
sets the base speed, which is then augmented by pitch control. Expression jacks: -multiplier:
this is where the dubstep happens. This expression control lets you sweep through multipliers, just like the multiplier knob, except when you're doing it with your foot, it lets you change divisions of the beat while you're playing. It's like a speed control, except whether you speed up or slow down you stay locked in tempo. This works whether you set the speed with the speed knob or the tap switch -cutoff frequency:
for slow filter sweeps
-Tap tempo switch
-True bypass switch
All of the controllers can be used simultaneously (main LFO, pitch-tracking LFO, envelope, expression pedal).
