140 Dual Envelope/LFO
Legendary Analog Dual Envelope/LFO Module for Eurorack762
Capabilities 2
Jacks 5 — 3 in / 2 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (3) | |||
| Ext LFO trigger | trigger | ≤10V | Connect a trigger signal to turn the LFO off until the end of the trigger cycle. Works with the Delay slider; LFO recovery takes about 20 seconds. A rear panel jumper can be removed to prevent re-triggering.762 |
| Ext gate | gate | 3V to 10V | 762 |
| Frequency CV input | cv | -10V to 10V | CV scaling is 1V/octave for controlling LFO frequency.762 |
| Outputs (2) | |||
| LFO OUT (inverting) | cv | — | Lower jack; sends inverting LFO waveform output to other modules.762 |
| LFO OUT (non-inverting) | cv | — | Upper jack; sends non-inverting LFO waveform output to other modules.762 |
