Hello all!
In the files section you can now find a v1.3 OS. This is version 1.2 but with free-running LFOs. Eventually I'll figure out making it a patch selection, but since I'm working only in 68k assembly that will be much more of an undertaking.
Special thanks to John Manfreda and his incredibly helpful Virtual VS software. This emulation uses the original ROM images so I didn't have to keep burning ROMs to test my code.
Enjoy, and let me know if there are any issues!
