I've probably mentioned this idea on here before but I wanted to lay it out as clear as possible and see what you guys have to say about it.
"Crossfade" would basically be the normal sync function but instead of both GBs starting at the same time they "take turns" whenever START is pressed on the master. As in: the master GB is playing and the slave is not, press start, now the slave is playing and the master is not, etc.
So you could do things like:
1. Easily make seamless transitions by having bridge sections on the master and your main tracks on the slave
2. Jump between beats breakcore-style
3. Stretch out your best tracks by sticking sections of other tracks in the middle or some junk i dunno
That's all assuming that you could navigate and load songs on the STOPPED gameboy while the other gameboy was still playing.
I think this is the same functionality as the current sync just with the slave start/stop reversed. Right? Seems easy enough the implement maybe?
