Another thing to check;
EXP (expression) dial in the mixer. This dial seems to default to zero lately (which is fine for an audio track, but not MIDI). Try turning this up if at zero (way up). Defaulting to zero results in no sound.
If set at zero it wouldn't matter if it was an external or internal synth .. ya ain't gonna hear it.


I do not work here, but the benefits are still awesome
Make your sound your own!
