Midi track freeze

Hi guys,
I’m trying to create audio tracks from Midi tracks by using th “freeze track” function, but th bounced audio track turns up empty with no audio (see attached screenshot).

Does anyone know what I’m doing wrong?

Apparently, you have an IAA synth (iPolysix) set to the track. But it looks as it’s not loaded (the instrument icon is a cross). Does this track make any sounds when played unfrozen and soloed?

This is correct, choosing “No instrument” will lead to an empty audio track when using the freeze function.
Please check, if our IAA tutorial is of help for you: https://www.youtube.com/watch?v=sDfZvwPrkTo
