How to initialize an EZOutput with floating point data?

[gghose]

Have spending quite a while backporting EZAudio to 10.5 (don't ask why I had to), it seems to be working. But now I'm not sure how to go beyond file reading and playback. I need to be able to compute arbitrary waveforms and have them play, which would seem to require initializing an EZOutput with raw data. But I don't see any obvious way of doing that (or alternatively creating an EZOutputDataSource with raw data). Can you someone point me in the right direction?
