As you can check on the diagram above, PercAll is based on four identical channels.
Each channel has a
VCA
circuit, which is internally controlled by a
Decay Envelope
circuit. This
envelope is fired via its TRIG Input and the time of the decay can be either controlled manually or
CV via its dedicated CV Input.
The module counts with two Choke circuits for channels 1-2 and 3-4.
When Choke switch is activated (Switch on top position), the TRIG signal of the first channel mutes
second channel's envelope. The obvious application to this is to make open-close hi-hat patterns
but we encourage you to get creative on this a try more stuff.
The
Strenght
input is a macro CV Input that affects to all envelopes amplitudes at the same time.
As the ratio of the envelope is constant, the falling time will be affected depending on the signal
plugged in, as well as the amplitude of the sound. This emulates the behaviour of a real
percussive instrument, where the release time depends on the energy applied to the membrane.
The audio
Output
of every channel is summed on a final mixing stage at Out 4. Inputs 1 to 3 are
normalized, so they will be taken out of the mix if you use that individual output.
