I have the Amiga version of the miracle piano and a friend of mine has the PC version. When I moved the cable got lost (somewhere) and now I can't used it since Software Toolworks would not sell me a cable or tell me how to make one. I tried the PC cable, after connecting a DB-9 to DB-25 converter to it, and it does not work. To check I pluged the same setup (including converter) to a PC and work OK. Now I have a nifty MIDI keyboard but I can not use the software for lack of cable. I hope someone out there can come up with a way of creating the cable. I heard that all it is is pin 2 and 3 crossed but I tried that and no luck. Yes my serial still works. I can use a modem and the PC to Amiga serial transfer programs.
