Freeze track - 32 bit stereo only?

[EmaDaCuz]

Hi guys.
I'm writing my music with Live but, since I have the Intro version, I like to export the single tracks and mix them in ProTools so to have more send/return and FX available.

Now, while everything is fine with recorded tracks (streo/mono 24 bit), I am a bit doubtful with the virtual instrument tracks. I mean, I am writing the drum parts, I freeze the track, soloing the single components (kick, snare, cymbals, toms...) and copy it to an audio track. When I check the file properties, all these tracks are stereo 32 bit. I have to admit they sound cool, but I can't afford working on 2 GB samples only for drums!!!
Is it possible to reduce the bit depth to 24 bit and have a mono file when needed (for example, kick and snare)?

Thank you very much.

Instead of using the Freeze function use "export audio" and you can choose the bit depth.

Hi, thanks. This is what I'm doing now, probably not the best choice but at least it works.
Any other idea, please do let me know.
