MiniMod Dual Contour
Two independent contour envelope generators in a single Eurorack module, closely replicating the Moog Model D contour generator circuit with exponential response, retrigger behavior, and switchable AD/ADSD modes per channel.1016
Capabilities 1
- Envelope Generatorenvelope-generator
- Dual independent ADSD (or AD) envelope generators replicating the Moog Model D contour circuit, with exponential slope and unique retrigger behavior.1016
Jacks 4 (2 in / 2 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (2) | |||
| Ch1 Gate | gate | 2V to 12V | Gate input that triggers envelope generation on a positive pulse; protected against negative voltages. Normalled to Eurorack bus trigger by default, overridden when a patch cable is inserted.1016 |
| Ch2 Gate | gate | 2V to 12V | Gate input that triggers envelope generation on a positive pulse; protected against negative voltages. Normalled to Eurorack bus trigger by default, overridden when a patch cable is inserted.1016 |
| Outputs (2) | |||
| Ch1 Envelope | cv | 0V to 8V | Envelope CV output, nominally 0–8 V; can reach up to 10.5 V when retriggered rapidly before the previous decay completes. An onboard jumper reduces output by 30% to accommodate retriggering headroom.1016 |
| Ch2 Envelope | cv | 0V to 8V | Envelope CV output, nominally 0–8 V; can reach up to 10.5 V when retriggered rapidly before the previous decay completes. An onboard jumper reduces output by 30% to accommodate retriggering headroom.1016 |
Parameters 10
| Name | Type | Range | Behavior |
|---|---|---|---|
| Ch1 AD/ADSD Switch | switch | — | Selects the envelope mode for Channel 1: switch up selects AD (no sustain) and switch down selects ADSD (sustain held until gate release).1016 |
| Ch1 Attack | knob | — | Sets the attack rise time for Channel 1's envelope with an exponential response curve.1016 |
| Ch1 Decay | knob | — | Sets the decay fall time for Channel 1; in ADSD mode also serves as the release slope since decay and release share the same curve.1016 |
| Ch1 Manual Trigger | button | — | Manually fires Channel 1's envelope once per press; independent from the Gate input and can be used simultaneously with it.1016 |
| Ch1 Sustain | knob | — | Sets the held output level for Channel 1 while the gate is high. Full range available (unlike the original Model D which was capped at ~80%); setting knob to 8.5 replicates original behavior. Inactive in AD mode.1016 |
| Ch2 AD/ADSD Switch | switch | — | Selects the envelope mode for Channel 2: switch up selects AD (no sustain) and switch down selects ADSD (sustain held until gate release).1016 |
| Ch2 Attack | knob | — | Sets the attack rise time for Channel 2's envelope with an exponential response curve.1016 |
| Ch2 Decay | knob | — | Sets the decay fall time for Channel 2; in ADSD mode also serves as the release slope since decay and release share the same curve.1016 |
