For values above 0, the dry signal level is constant and the delay signal level rises with the
parameter value.
The delay feedback is set via parameter 0.

This algorithm implements a resonator, which is a kind of filter, but which is also often found as the
basis for analogue drum synthesis.
X is the input for the signal to filter. If used as a drum synth, this is the trigger input. The amplitude
and nature of the trigger signal will affect the resulting sound. If parameter 1 is set to '1', the input is
treated as an actual trigger, not an audio signal, triggering a pulse when the input goes over 1V.
Y sets the pitch of the resonator, with a 1V/octave response. The 0V point for the pitch input is C3
(approximately 130.81Hz). Parameter 0 provides a pitch offset in semitones.
Z sets the gain. In terms of drum synthesis, more gain means a longer decay time.
A is the audio output.
B outputs the result of envelope tracking the audio output A.
Pressing Z simulates hitting X with a 1ms 5V pulse, and so works as a manual trigger of the 'drum'.
C-6 Vocoder
X is modulator input
Y is carrier input
Z sets the decay time
A is audio output
B is envelope output

This algorithm implements a vocoder. The spectral characteristics of the modulator input are
applied to the carrier input. In classic usage, the modulator might be a human voice, and the carrier
might be a synth sound, or simply noise.
