Good Day All,
Before I post this to Cakewalk support (who are nice people but take a little bit of a while to respond) I thought I would ask here first, especially if the Z3TA+ developer reads posts here.
Anyway, the problem is simple. Certain instruments (I can provide the ones I have discovered later, but I don't have a comprehensive list as I only got the Z3TA+ recently in the $20 deal) do not render audio when you do a File -> Export Audio in Ableton. I have since discovered that if ANY parameter is set to 2.0x oversampling they simply won't play in an Audio export though they WILL play in the track normally when previewing it while working.
I am "guessing" that this has something to do with offline vs online rendering but I am no expert.
My biggest frustration with this is that you don't know a track with Z3TA+ on it isn't rendering until after your final export because it plays perfectly in Ableton normally.
Any help would be greatly appreciated.
