Pluck Envelope

CV Generators

1. Pluck Knob Adjusts the decay time of the pluck envelope.
2. Vel Knob Controls how much the amplitude of the pluck envelope is affected by the signal on the Vel input.
3. Curve Knob Shapes the decay of the pluck envelope, from logarithmic to exponential.
4. Pluck Output Outputs the individual signals for Pluck A and Pluck B.
5. Vel Input Modulation input designed for amplitude control, typically connected to the Keyboard Vel output. Modulation depth is adjusted with the Vel knobs.
6. Trig Input Simultaneously triggers both pluck envelopes.
7. Mix Knob Balances the contribution of Pluck A and Pluck B in the Mix output.
8. Mix Output Outputs a combined signal of the Pluck A and Pluck B envelopes.

Overview ⚓︎

The Pluck Envelope generates two envelope signals that start at 10V and decay to 0V.

This simple envelope shape is ideal for controlling the amplitude or filter cutoff of plucks, stabs, basses or keys.

Usage ⚓︎

• Connect a trigger signal such as the Keyboard Trig or Sequencer Pulse to the Trig input.
• Connect the envelope signal to a VCA to control the volume of the sound, or to any other modulation target. There are three envelope outputs (see figure below):
  • Pluck A output
  • Pluck B output
  • Mix output, a user-defined mix of both envelopes
• Adjust the envelope decay times using the Pluck knobs.
• Optionally, connect a velocity signal to the Vel input and adjust its effect for each envelope with the Vel knobs.

In Depth ⚓︎

Both Pluck A and Pluck B envelopes start simultaneously when a trigger signal is detected at the Trig input.

If no velocity signal is applied to the Vel input, the initial amplitude will be 10V. Otherwise, it will depend on the voltage at the Vel input and the position of the Vel knob in each section.

By default, the envelope signal on the Pluck A and B outputs will linearly fall down to 0V. Both envelopes have a curve knob to adjust the decay curve, from logarithmic—which is great for stabs and electronic percussion—to exponential—which mimics the natural decay of acoustic instruments.
