Patch Ideas:
Animated Lead:
Patch sequencer or keyboard CV to VCO B 1V/ Octave INput. Monitor VCO B FINAL OUT. Set SHAPE and
ANGLE panel controls and CV Attenuators to NOON. Set FOLDS to 9 o' Clock and set FOLDS CV attenuator
to NOON. Set Mod Bus panel control to NOON. Patch Gate from sequencer or CV KB to STRIKE INput of
DPO. Push button to select LFO behavior at VCO A. Set VCO A FREQ. to around 9 o' Clock and set Follow p
to full clockwise (100%). Varying the Mod Bus parameter will greatly alter the sound.
Analog Bass Drum: Patch VCO A SINE to Optomix CH. 1 Signal IN. Patch Gate from René or other
sequencer to DPO VCO A Linear FM IN and Optomix CH. 1 Strike IN. Set DPO VCO A Linear FM amount to
50% and Frequency panel control to roughly 9 o' clock. Set Optomix CH. 1 Damp and Control panel controls
to full Counter Clock-Wise. Monitor Optomix CH. 1 Signal OUT. Adjusting the Linear FM amount, Frequency
setting and DAMP settings will allow you to create many different Bass Drum sounds. Adding Dynamic Expo
FM from VCO B by patching same gate to FM INDEX IN will also expand the possibilities.
Skronky FM
Engage SYNC mode on VCO A. Monitor VCO B SINE Output. Tune the two oscillators to a simple interval
such as unison, a fifth or an octave. Adjust FOLLOW panel control to about 3:00. Turn up VCO B Lin FM
attenuator to 12:00. Turn FM BUS to 12:00. Send a sequence or keyboard voltage to VCO B 1v/oct. Each
note change will be accompanied by a discordant squelch of FM as VCO A “slides” to the correct note. Adjust
Follow and FM amounts to taste.
Strike Force
Monitor FINAL output. Turn Folds and SHAPE to 0 (full CCW). Turn SHAPE and FOLD CV input attenuators
to 12:00. Patch Pressure Points common Gate out to STRIKE input, Pressure Points tuned voltage B or C to
DPO VCO B 1v/oct, and Pressure Points common Pressure out to Mod Bus EXT SRC Input. Sound will
become simultaneously louder and more “damped” as more pressure is applied. Adjust Pressure Points
sensitivity and SHAPE/FOLD CV input attenuators to taste.
Wobble Bass
Monitor FINAL output. Adjust Fold, Angle, Shape panel controls and input attenuators to 12:00. Set VCOA to
LFO mode with coarse Freq ~9:00. Adjust Mod Bus Index Panel control full CW, and FM Bus Index panel
control full CCW. Adjust Follow panel control full CW. Patch sequencer or keyboard CV to VCOB 1v/oct.
"Wobbling" will change speed with the pitch of the “bassline”, doubling frequency per octave. Adjust coarse
frequency knobs and Final parameters and CV input attenuators to taste.
