5.8 CV Operation
APC64 features eight CV/Gate ports which can be used to connect to and control other CV-compatible devices,
such as synthesizers or drum machines. Use standard 1/8” (3.5 mm) TS cables to send a single CV/Gate signal per
output.
Use APC64’s 5.6 Global Menu to access the following CV setup options:
The CV1–8 Source options (odd numbers between 5 and 19 in the Global Menu) determine what type of MIDI
messages the CV port receives.
Pitch: Note messages are sent as CV Pitch messages.
• Last: The pitch will change to its new value each time a note message is received.
• Low: The pitch will change when the new note value is lower than the current value.
• High: The pitch will change the new note value is higher than the current value.
Gate: Note messages are sent as Gate messages, which open and close to trigger note ons and note offs.
• Last: The gate is retriggered each time a note message is received.
• Low: The gate is retrigged when the new note value is lower than the current value.
• High: The gate is retrigged when the new note value is higher than the current value.
• Legato: The gate is only retrigged when all held notes are released and then a new note is triggered.
Velocity: Note messages are translated into velocity values, variable between 0–5 V.
• Last: The velocity will change each time a note message is received.
• Low: The velocity will change when the new note value is lower than the current value.
• High: The velocity will change when the new note value is higher than the current value.
• Legato: The velocity will change when all held notes are released and then a new note is triggered.
Aftertouch: Channel aftertouch messages on the current channel are sent as a variable CV signal between
0–5 V.
CC 16–23: Continuous controller (CC) messages on the current channel are sent as a variable CV signal
between 0–5 V.
Fader 1–8: Messages from the selected fader are sent as a variable CV signal between 0–5 V.
Drum 01–16: The selected drum pad will send a gate message when pressed.
The CV1–8 Channel options (even numbers between 6 and 20 in the Global Menu) determine what MIDI channel
each CV port receives messages from.
