Sounds like the sound effect they use on the simpsons when something gets irradiated. Play the M2 key (A#1) when octave is set to 3. Adjust peak to your liking. It just adds more bass.
the first step is:
tempo at 240 & push PLAY
step 2:
touch and record randomly the notes from
the pitch 1,2 and 3 in the lowest octave
step 3:
get a more natural and random sound
deleting steps with Active Step
Hope you like it!
LFO rate = rt.04,
LFO INT (0) < (50)% ,
play with the :
VCF CUTOFF,
shift LFO accents using FUNC + RATE,
turn off CUTOFF modulation FUNC + M6 = sidechain compression effects,
play with the:
PEAK, CUTOFF EG INT, LFO INT
Modulate the EG decay and release ad mod the filter cut ad res. You can make a good wobble effect if you put some attack on the filter. I used a DS-1 Distortion Pedal with it. I turned down the volume on the volca so the pedal was acting more as an amplifier giving it some saturation.
