Not seeing signal

Meters flat? The SEQTRAK routes audio over USB only while it is powered on and playing — check the machine's own volume too.

Mono input? macOS sometimes defaults the device to 1 channel. Open Audio MIDI Setup and set the SEQTRAK input to 2 ch, then rescan.

Nothing in the list? Some hubs hide USB audio. Try a direct USB-C cable.
