Dual pingable envelope generator whose envelope lengths are set by the time between clock pulses or 'pings', with full CV control of envelope shape, skew, and ping division/multiplication, plus triggering and cycling options.377
Capabilities 3
Clock Sourceclock-source
EOF jack can be reassigned via System Mode to output Tap Tempo Clock, enabling the PEG to function as a master clock source.377
Envelope Generatorenvelope-generator
Dual pingable envelope generator; envelope lengths set by time between ping pulses, with CV control of div/mult, skew, and curve.377
LFOlfo
Each channel can self-cycle in LFO mode via the Cycle button, locked to the ping clock.377

Description
Inputs (7)
Async
gate
—
Asynchronous trigger/gate input. Triggers immediate envelope start; holding gate high creates A-S-R envelope (sustain until gate release). Puts channel into Async mode (no sync to ping clock).377
Clock/trigger input that sets the ping timing. Only the timing between the last two pulses is used. When a gate is received on the Ping jack, the tap tempo clock is disabled.377
QNT
gate
—
Quantized trigger input; envelope starts at the next ping clock. Holding a gate high causes the envelope to repeat. Also exits Async mode and enters Sync mode.377
Cycle Toggle jack. While a gate is high, both channels' Cycle buttons toggle state; they revert to previous state when gate is released.377
Outputs (6)
+5V ENV
cv
0V to 5V
Non-scaling envelope output that always produces a 0V to +5V envelope regardless of Scale and Bi-polar settings. Useful as auxiliary envelope output.377
ENV
cv
-10V to 10V
Main envelope output. Amplitude controlled by Scale knob and Bi-polar button. Range from -10V to +10V depending on Scale and Bi-polar settings.377
EOF
gate
—
End-of-Fall gate/trigger output. Goes high when fall segment ends; goes low when a rise segment ends. Stays high when envelope is not running. Can be reassigned to Tap Tempo Clock output or trigger mode via System Mode.377
EOR
gate
—
End-of-Rise gate/trigger output. Goes high when fall segment begins; goes low when envelope completes. Stays low when envelope is not running. Can be reassigned to Half-Rise or trigger mode via System Mode.377
Half-Rise
gate
—
Half-Rise gate output. Goes high when 50% of rise time has elapsed; goes low when 50% of fall time has elapsed. Gate width is always 50% of envelope time. Skew changes phase but not width.377
OR
cv
—
Analog OR output — outputs the highest voltage from either channel's scaled ENV output at any given moment.377

Range
Behavior
Bi-polar
button
—
Level-shifts the ENV output before the scale/inverter. Factory setting shifts by -5V so 0V–+10V becomes -5V–+5V. Amount is adjustable via rear trim pot.377
Curve
knob
1 – 17
Selects one of 17 envelope curve shapes. Asymmetrical curves at extremes (expo attack with varying decays; log attack with varying decays). Symmetrical curves in the center (expo through linear through log). Knob sets offset for applied CV.377
Cycle
button
—
Toggles self-cycling (LFO) mode. When lit, envelope runs continuously without external triggers. In Sync mode, starts from a point such that envelope ends on next ping clock. In Async mode, starts from 0.377
Ping Div/Mult
knob
—
Sets division or multiplication of the ping clock from /8 to x8 in whole number increments. Knob sets center offset for applied CV. Changing this while envelope is running immediately changes slope; after ~50ms with no further change, envelope re-syncs to ping clock.377
Ping button
button
—
Tap at least twice to set ping tempo. Two taps set period; third tap (within 50%-200% of period) averages. Hold 2s to clear tempo. Hold 5s to enter System Mode.377
Scale
knob
—
Attenuating inverter for ENV and OR outputs. Right of center: positive-only output up to +10V. Left of center: inverted negative-only output down to -10V. Center produces no output. With Bi-polar on, right of center rises from negative to positive (-5V to +5V range).377
Skew
knob
—
Controls ratio of rise to fall time while keeping total envelope length constant. Fastest rise time normally 10µs, fastest fall time 200µs. Skew Limiting mode sets minimum rise/fall to 6ms.377
