Now "just" to write an editor...

It's about a third of a VBL at the moment but that's because I haven't quite got my head around using addx in addition to swap, which will bring the VBL time down a bit then that could be brought down even more by going mono or 25kHz. It's sounding good enough now that I think I want to take it down the quality route rather than possibly compromising the sound for CPU performance.
It's actually not entirely impossible to write tune data directly into the source file and for it to almost look pretty much like it would as a tracker. I've got a couple of things I want to finalise with effects then I'll pop a copy up if people are interested in having a play.
