Hi I could have sworn that with previous versions of Logic that bouncing tracks that used the Quicktime Synth for playback of MIDI tracks used to render the QT MIDI to audio within the bounce file. [Currently using the latest version of Logic Pro.] That doesn't seem to be the case anymore, unless I'm missing something. If I am missing something then what is it? I've got tons of old writing Projects that used the QT Synth for audio playback of MIDI tracks and now, if I want to mix them down to audio, I'm forced to use Software Instruments on the QT Synth tracks instead - and it's a bit of a PITA. Any way around this?
