oh my GOD.

Say, blackhole, what are the limits on NSPC? Like, number of instrument tracks, how long the song can go for before looping, etc?

Limits of the N-SPC:
- 8 DSP channels, which means you can play up to 8 samples simultaneously.
- 255 instruments, but the amount of samples is practically limited by the space available. Yet, you can always make multiple instruments use the same sample, with the ADSR envelope being the only difference.
- Length of songs, loops etc. only limited by available space. By writing a "live uploader" routine (that would involve SPC-700 assembly hacking) you could make songs of virtually infinite length, but you would lose the ability to produce suitable SPC dumps.
- You can change an instrument as often as you wish within a track. Same applies to other things like echo.
- Samples use a lossy compression method (BRR) at 32 KHz and 16 bit precision.

There might be some more, but that's all I can think of now (being at my school's computer science room).

@turtleman ...... no comment. ;;;

Not quite... You could do some ASM hacking to upload new data to the SPC700. If you do it right I imagine you'd have pretty much unlimited space. Problem being, of course, that it'd be difficult and probably take quite a while to load.
