- Well, yeah -- sample data for playback has to go in Chip. I'm not
- sure whether sampling has to record to Chip (I haven't written my
- sample routine yet). Regardless, though, the machine has enough time
- to toss data between Fast and Chip as necessary (if your program uses
- double-buferring) when playing back, at least. It seems that Music-X
- should be able to do this, too -- if there's not too much system
- overhead, anyway. (Maybe Music-X demands too much else, and just can't
- double-buffer while it's playing...I don't have Music-X, so I don't
- know.)
