The saw and pulse, are really clicky, because there's no low-pass filter to remove the hard edges (and thus high frequency components), they too will sound more like good ol' crappy chips as soon as I get that implemented.
Actually it wasn't too much work. I've done all of this in less than a week in my spare time. I've just been reading Wikipedia, data sheets, and an interview with the chip developer, and coding up parts of the chip as I understand them to work. I'm not going for 100% accurate emulation (the computer didn't have MIDI support anyway), just something that sounds very close.
I've been reading up on filters last night and today. I think I'm getting a grasp on how to make one now. So I'll probably have it in place today or tomorrow.
