Dual voltage-controlled integrator/function generator based on the Serge/Buchla ramp generator concept, with slope detectors, analogue logic functions, and combined outputs.1132
Capabilities 6
- Envelope Generatorenvelope-generator
- Patch-programmable as attack-decay, attack-sustain-release, or more complex ADSR-style envelopes by using the gate/trigger inputs with RISE and FALL faders.1132
- Function Generatorfunction-generator
- Dual Serge/Buchla-style ramp generator (two voltage-controlled integrators) producing rise/fall functions usable as envelope, LFO, or slew.1132
- LFOlfo
- Operates as an LFO or VCO by placing the CYCLE switch in cycle mode; supports triangle, sawtooth, and square waveforms.1132
- Lowpass Filterlowpass-filter
- Acts as a basic low-pass filter when audio is patched to IN with RANGE set to the High (fast) setting and RISE/FALL faders adjusted.1132
- Slew Limiter / Portamentoslew-limiter
- Voltage-controlled slew limiter with independent attack/decay and continuously variable shape from logarithmic through linear to exponential; suitable for portamento on pitch CV.1132
- Slope Detectorslope-detector
- Dual slope detectors output 10V gates when the respective channel output is rising or falling, enabling gate extraction from analog signals.1132
Jacks 21 (10 in / 11 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (10) | |||
| CH1 CYCLE | gate | — | Inverts the CYCLE switch state; does not trigger the ramp, only puts the channel into cycle mode.1132 |
| CH1 FALL CV | cv | — | CV input for controlling fall time on channel A remotely.1132 |
| CH1 IN | mixed | — | Signal input accepting CV or audio; inserting a gate converts it into an AD envelope with sustain.1132 |
| CH1 RISE CV | cv | — | CV input for controlling rise time on channel A remotely.1132 |
| CH1 TRIGG | trigger | — | Triggers the internal function generator for channel A; in cycle mode acts as hard sync input.1132 |
| CH2 CYCLE | gate | — | Inverts the CYCLE switch state for channel B; does not trigger the ramp, only puts it into cycle mode.1132 |
| CH2 FALL CV | cv | — | CV input for controlling fall time on channel B remotely.1132 |
| CH2 IN | mixed | — | Signal input accepting CV or audio; inserting a gate converts it into an AD envelope with sustain.1132 |
| CH2 RISE CV | cv | — | CV input for controlling rise time on channel B remotely.1132 |
| CH2 TRIGG | trigger | — | Triggers the internal function generator for channel B; in cycle mode acts as hard sync input.1132 |
| Outputs (11) | |||
| B>A | gate | ≤10V | Comparator output; outputs 10V when channel B's output level exceeds channel A's.1132 |
| CH1 EOC | trigger | ≤10V | End-of-cycle pulse output for channel A; fires a short 10V pulse when the internal generator reaches 0V. Does not work with external signals.1132 |
| CH1 FALLING | gate | — | Gate output active during the fall phase of channel A.1132 |
| CH1 OUT | cv | — | 1132 |
| CH1 RISING | gate | ≤10V | Slope detector output for channel A; outputs 10V gate while the channel output is rising.1132 |
| CH2 EOC | trigger | ≤10V | End-of-cycle pulse output for channel B; fires a short 10V pulse when the internal generator reaches 0V. Does not work with external signals.1132 |
| CH2 FALLING | gate | — | Gate output active during the fall phase of channel B.1132 |
| CH2 OUT | cv | — | 1132 |
| CH2 RISING | gate | ≤10V | Slope detector output for channel B; outputs 10V gate while the channel output is rising.1132 |
| MAX | cv | — | Analog OR output; continuously outputs whichever of the two channel outputs is higher at any moment; also functions as a peak follower.1132 |
| MIN | cv | — | Analog AND output; continuously outputs whichever of the two channel outputs is lower at any moment.1132 |
Parameters 13
| Name | Type | Range | Behavior |
|---|---|---|---|
| A>B | knob | — | Crossfades channel A and B signal levels going into the mix section, affecting the A>B, MIN, and MAX outputs but not OUT A or OUT B directly.1132 |
| CH1 CYCLE Switch | switch | — | Selects one-shot mode (stops at 0V) or cycle mode (re-triggers at 0V to act as a function generator) for channel A.1132 |
| CH1 FALL | fader | — | Sets the fall time for channel A using the same principle as the RISE fader.1132 |
| CH1 RANGE | switch | — | Selects operating speed: High (small dot) for audio-rate applications, Medium, or Low (big dot) for LFO and long envelope applications.1132 |
| CH1 RISE | fader | — | Sets the rise time for channel A; fader up increases rise time. In cycle mode or LPF use, moving fader up decreases frequency.1132 |
| CH1 SHAPE | switch | — | Switches the integrator's curve between exponential and other response shapes for channel A.1132 |
| CH1 TRIG Button | button | — | Manually triggers the internal function generator for channel A when pushed.1132 |
| CH2 CYCLE Switch | switch | — | Selects one-shot mode (stops at 0V) or cycle mode (re-triggers at 0V) for channel B.1132 |
| CH2 FALL | fader | — | Sets the fall time for channel B using the same principle as the RISE fader.1132 |
| CH2 RANGE | switch | — | Selects operating speed for channel B: High for audio-rate, Medium, or Low for LFO and long envelope applications.1132 |
| CH2 RISE | fader | — | Sets the rise time for channel B; fader up increases rise time. In cycle mode or LPF use, moving fader up decreases frequency.1132 |
| CH2 SHAPE | switch | — | Switches the integrator's curve between exponential and other response shapes for channel B.1132 |
