Full wave rectifier
Ingredients:
Signal source
MOTM-700 Dual VC Router (1 stage)
Oakley OMS-802 Mixer/Triple Attenuator (need gain of -1)
Signal source to MOTM-700 CV IN and IO B
Signal source to OMS-802 IN1
OMS-802 OUT1 to MOTM-700 IO A
OMS-802 IN 1 knob at -5
MOTM-700 switch knob at 0
MOTM-700 mode switch to voltage
MOTM-700 output is full wave rectified waveform
Pulse Divide by Two
This divides a square wave frequency by two. Good for clocking/gate
applications or suboctave square waveforms.
Required Modules:
320 VCLFO or 390 uLFO or 300 VCO
700 VC Router
Oakley Multimix (MOTM mixer does not have enough gain, need gain of -1)
910 Cascaded Multiple
Connections
300/320/390 TRIANGLE to 700 CV IN
300/320/390 SQUARE/PULSE (set pulse at 50%) to MULT (Note: this needs to
be the same oscillator as the triangle wave)
MULT to Oakley Multimix IN1 and 700 IO A
Multimix OUT1 to 700 IO B
700 IO X is divided square out
Settings:
300/320/390 Rate/Frequency = any
700 Mode = voltage
700 Switch = 0 for square wave, any other setting for uneven pulses
Oakley Multimix IN 1 = -5
For modulation of pulse width, mix the TRIANGLE wave with a second LFO
sine or triangle, then feed that to the 700 CV IN.
Syncopated Clock with Random Probability
Another application for the lowly MOTM 700. This gives a nice
syncopated, semi-random clock, but always on the beat.
Required Modules:
100 or 101 Noise/S&H
320 VCLFO or 390 uLFO
700 VC Router
830 Dual Mode Mixer
910 Cascaded Multiple
Connections
320 PULSE or 390 SQR to Mult
Mult to 100/101 EXT CLK, 830 IN 3, 700 IO A
100/101 S&H OUT to 830 IN 2
830 OUT1 to 700 CV IN (A/B/X)
700 IO X is syncopated clock, send to ADSR gates
Settings:
100 LEVEL = 10, SLEW = 0
320 or 390 RATE = about 8
700 SWITCH = +0.5 to +3.5
830 IN 2, IN 3, BIAS (optional) = set to taste
Semi-random patch
Ingredients:
Any 2 LFOs
MOTM-700 Dual VC Router
MOTM-820 VC Lag
Any LFO 1 waveform to 700 IO A
Any LFO 2 waveform to 700 IO B
700 IO X to 820 IN
820 OUT1 to 700 CV IN
820 OUT2 to any control voltage input, VCO pitch, VCF cutoff, etc.
LFO rate, Router switch, and Lag Up, Down and Up/Down will cause
significant change to the semi-random pattern. Adjusting the Lag
control too far to the right may cause the Router to stay pegged to one
side. The patch creates a feedback path so that lagged versions of LFO 1
and LFO 2 alternate control of the router switching.
