This is a gate voltage that is produced each time MIDI note 01 is received.
This could, for example, be patched to the Sequencer’s RESET input, so the sequencer can
be programmed to reset using MIDI Note 01.
SAMPLE & HOLD (S+H)
A sample and hold will ‘record’ a voltage level and hold it there.
SIG IN socket
Patch the CV to be sampled into here, typically an EG or LFO, or patch in white noise.
CLOCK IN socket
Each time the input signal goes high the input signal will be sampled and held, until the next
clock.
Typically use the square wave output from an LFO, or, the Gate signal from the MIDI
converter.
SIG OUT socket
This is the CV output from the sample and hold circuit. Maybe try patching this to filter cut-off
or VCO pitch.
A typical use of S+H is to create a stepped random voltage. To do this patch Noise to the
SIG IN, LFO square wave to the CLOCK IN.
