multitrack audio playback

Any thoughts on an approach to multitrack playback ?

I want to synchronize the playback of 'n' virtual channels of audio in a multi-track audio recording app. I've been thinking that I could either use a single AudioDevice and merge all the audio data for my channels in the playback ioProc or I could use a separate AudioDevice per channel and let Core Audio merge the data, but I worry that having multiple ioProcs being called might create a greater processor load and it might be a little trickier to guarantee everything stays in sync.
