Cascade by Qu-Bit Electronix: Ratcheting envelope generator, VCA, sound source, compressor, and envelope follower.
| Knob | Function | CV Input | Range |
|---|---|---|---|
| Attack | Envelope attack time | Yes | 0.5 ms – 5 s |
| Decay | Envelope decay/release time | Yes | 0.5 ms – 10 s (or 5 s) |
| Curve | Changes envelope curve (logarithmic–linear–exponential/response) | Yes | |
| Repeats | Ratchet (# repeats, clock multiplier, or loop) | Yes | 1–16/infinite loop, 1x–16x |
| Level | Envelope output level | Yes | 0–10V |
| Offset | DC offset to envelope | Yes | 0–10V |
| Sustain | (ADSR mode only) Sustain level | No | 0V–Level knob setting |
| Threshold | (Follower/Compressor) Signal threshold | No | |
| Ratio | (Compressor) Compression ratio | No |
| Button | Function |
|---|---|
| Trig | Manually trigger envelope |
| Invert | Flip envelope (maintains selected voltage range, Green LED on) |
| Mode | Cycle through main modes (AD/ASR/ADSR/Follower/Compressor/Ratcheting, etc) |
| Shift | Shift for Edit/secondary functions |
| Jack | Type | Function | Voltage Range |
|---|---|---|---|
| Trigger | Input | Triggers the envelope/controls repeat tempo | Gate/Trigger (0–5V/10V) |
| VCA In | Input | Audio input to VCA (feeds internal VCA and Follower/Compressor modes) | Audio/CV |
| VCA CV | Input | Overrides envelope out for external VCA control | 0–10V CV |
| Invert | Input | CV for inverting envelope | 0–10V |
| GATE | Output | Configurable: gate/trigger (varies by Edit Function) | 0–10V |
| VCA Out | Output | Audio out (external/internal source, enveloped/compressed etc.) | Audio/CV |
| ENV | Output | Envelope CV out bundle | 0–10V |
| Mode | Unique Controls/Notes |
|---|---|
| Ratcheting AD | Repeats ratcheted, clock-multiplied envelopes |
| AD | Basic Attack/Decay envelope (optionally looped) |
| ASR | Gate controls sustain; loopable |
| ADSR | Classic four-stage envelope |
| Envelope Follower | Follows input amplitude, outputs CV/gate |
| Compressor | Audio compression w/ virtual sidechain trigger |
