Prophet 64 cart coming soon..
Well, the maker(s) of Prophet 64 are going to release a C64 cartridge containing updated versions of the three Prophet 64 programs, a (pre-audio) Logic-like sequencer, and built-in DIN Sync. They've got together with Firestarter to release a MIDI interface for the C64 that is a perfect compliment to Prophet 64. No firm price yet, but check this: get yourself a used C64 (~$75), the cartridge (~$49), and the MIDI interface (<$50) and you've got a synth that, aside from having massive indie cred, will wipe the floors with a SIDstation. All current info about the cartridge is on the Prophet 64 site. AI gives this two big thumbs up, and a strong "buy" recommendation.
