Percall
A percussive quad decay envelope and VCA module with four channels, choke control, a strength input affecting all envelopes, and a normalised submix output.933
Capabilities 4
- Decay Envelopedecay-envelope
- Each channel has its own decay envelope triggered by a TRIG input; decay time is controllable manually or via CV.933
- Mixermixer
- Channels 1–3 are summed at the channel 4 output, which acts as a master mix out; individual outputs remove their channel from the mix when patched.933
- Percussionpercussion
- Shapes external audio sources into percussive hits via gated decay envelopes; includes choke control for hi-hat style muting.933
- Voltage-Controlled Amplifiervca
- Four independent VCA circuits, one per channel, internally controlled by a dedicated decay envelope.933
Jacks 21 (13 in / 8 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (13) | |||
| CH1 Decay CV | cv | — | CV input for controlling the decay time of channel 1's envelope; summed with the manual decay knob.933 |
| CH1 IN | audio | — | Audio input for channel 1; normalled to CH2 IN when CH2 IN is unpatched.933 |
| CH1 TRIG | trigger | — | Trigger input that fires the decay envelope for channel 1; also drives choke muting of channel 2 when choke is enabled.933 |
| CH2 Decay CV | cv | — | CV input for controlling the decay time of channel 2's envelope; summed with the manual decay knob.933 |
| CH2 IN | audio | — | Audio input for channel 2; receives CH1 IN signal when unpatched (normalled from CH1 IN).933 |
| CH2 TRIG | trigger | — | Trigger input that fires the decay envelope for channel 2.933 |
| CH3 Decay CV | cv | — | CV input for controlling the decay time of channel 3's envelope; summed with the manual decay knob.933 |
| CH3 IN | audio | — | Audio input for channel 3; normalled to CH4 IN when CH4 IN is unpatched.933 |
| CH3 TRIG | trigger | — | Trigger input that fires the decay envelope for channel 3; also drives choke muting of channel 4 when choke is enabled.933 |
| CH4 Decay CV | cv | — | CV input for controlling the decay time of channel 4's envelope; summed with the manual decay knob.933 |
| CH4 IN | audio | — | Audio input for channel 4; receives CH3 IN signal when unpatched (normalled from CH3 IN).933 |
| CH4 TRIG | trigger | — | Trigger input that fires the decay envelope for channel 4.933 |
| Strength IN | cv | ≤10V | Macro CV input affecting all four envelopes simultaneously; controls both amplitude and decay time. Normalled to 10V so all envelopes run at maximum strength when unpatched.933 |
| Outputs (8) | |||
| CH1 ENV OUT | cv | 0V to 10V | 933 |
| CH1 OUT | audio | — | Audio output for channel 1; when patched, this channel is removed from the master mix at CH4 OUT.933 |
| CH2 ENV OUT | cv | 0V to 10V | 933 |
| CH2 OUT | audio | — | Audio output for channel 2; when patched, this channel is removed from the master mix at CH4 OUT.933 |
| CH3 ENV OUT | cv | 0V to 10V | 933 |
| CH3 OUT | audio | — | Audio output for channel 3; when patched, this channel is removed from the master mix at CH4 OUT.933 |
| CH4 ENV OUT | cv | 0V to 10V | 933 |
| CH4 OUT | audio | — | Audio output for channel 4; also serves as the master mix output summing channels 1–3 (when those channels are unpatched at their own outputs).933 |
Parameters 6
| Name | Type | Range | Behavior |
|---|---|---|---|
| CH1 Decay | menu_setting | — | Controls the tail length of the decay envelope; combined with the CV decay input (both are summed together).933 |
| CH1-2 Choke | switch | — | When set to the up (active) position, a trigger on channel 1 mutes channel 2's envelope, enabling open/closed hi-hat style behavior.933 |
| CH2 Decay | menu_setting | — | Controls the tail length of the decay envelope; combined with the CV decay input (both are summed together).933 |
| CH3 Decay | menu_setting | — | Controls the tail length of the decay envelope; combined with the CV decay input (both are summed together).933 |
| CH3-4 Choke | switch | — | When set to the up (active) position, a trigger on channel 3 mutes channel 4's envelope, enabling open/closed hi-hat style behavior.933 |
| CH4 Decay | menu_setting | — | Controls the tail length of the decay envelope; combined with the CV decay input (both are summed together).933 |
