The mono/stereo interleave button is available on audio tracks only. It is not available on instrument tracks but instrument tracks only record MIDI data. When inserting a soft synth using a regular audio and MIDI track instead of an instrument track or bounce the instrument track to mono after recording the MIDI data.
Thanks, I realize that. I am recording audio on an audio track from a mic that is mono. I don't know if it's my interface, a Roland Duo-Capture EX, but all the new tracks I create are stereo. I thought I devised a work-around by setting it to either L or R, but then no sound is recorded. I wish I could create a mono audio track. :(
