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.
C-5 Resonator
Video
X is audio or trigger input
Y is centre frequency (pitch)
Z is gain
A is audio output
B is envelope of audio output
Z press is 'strike'
Parameter Min Max Default Description
0 -32 32 0 Applies an offset to the Y input.
1 0 1 0 Mode.
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
Video
X is modulator input
Y is carrier input
Z sets the decay time
A is audio output
B is envelope output
Parameter Min Max Default Description
0 0 1 0 Selects the filter bank.
1 0 64 16 Output A attenuation/gain.
2 0 64 16 Output B attenuation/gain.
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.
