You can check out the Blaster Master SNES music I made for Super Mario Crossover 2 as references if you'd like.
Go find Schism Tracker or Modplug Tracker, those are two good tracking softwares for .IT files. Schism Tracker is an Impulse Tracker (90's Tracker) clone. I grew up on that software so it's second nature to me.
You could easily shorten those samples a bit more. Oh and the program works. I wish I knew this program existed before. Do you still need a compressor to fit large samples in the SPC because anything over 64KB doesn't play in foobar.
*Edit*
No, sm3 doesn't seem to be working with the converter.
Why should I shorten the samples? They work the way I intend them to, and every SPC player that the songs are intended to play in play the files fine.
It's not like they're going to be used in a commercial game. They're intended to be used in Super Mario Crossover 2, and they are. They also play perfectly.
Besides, I quite like the way the SPC700 handles them.
If you intend to use lots of samples , shorting the samples is a sure way of saving ram. But I'm sure you already know about the 64KB ram limitation right?
I've looked everywhere for a good SNES tracker and can't seem to find a good one(or any at all).
Does someone with more moxie then me know of a way to emulate the SPC700?
I have lots of soundbanks, but whenever I throw them into a program they sound too new.
Actually, I've read a thread topic in the Nesdev forums and using the SPC700 tracker is more time consuming because you can't test your song to see how it sounds while you're editing it because it's not much like your average chip music tracker. I would just get a converter because you have to keep compiling the same file over and over. I'd suggest sticking to some thing more convenient like MilkyTracker because sound files can be compressed to .xm files which the converters you are talking about should be able to convert xm files to .spc files.
