Using the SQ-1 as a MIDI-CV converter
When the SQ-1 receives a note message via USB MIDI, it outputs the corresponding CV and GATE, allowing you to use the SQ-1 as a MIDI-CV converter. However, if the SQ-1 itself is outputting a CV, such as while the sequencer is running, that operation takes priority, and MIDI-CV conversion is not performed.
