I recorded MIDI samples back around 1992 using a sequencer program whose name eludes me (it began with an 's' I believe) on an old Atrai 1024 STE. the problem was that the program could only store files with an extension .mus rather than the standard .mid format so I cannot do anything with them now. Does anyone remember this sequencer / file format and does anyone know of any converters which can convert the data into standard MIDI files?
