Mssiah is a very powerful music application that turns the C64 into a analogue mono synth with full midi. The C64 can be played or sequenced/programmed by the C64's keyboard (in partnership with joystick or paddles) or via either external midi keyboard, DAW (eg Ableton, Cubase, Protools etc) or by any hardware sequencer that transmits midi. The Mssiah responds to both CC and midi commands. It is also viable to sync the C64 via DinSync (old roland gear, tr606/tr808/mc202/tb303 etc)
The very special thing about this particular C64 is that it has the R5 8580 sid chip (see picture for verification). The 8580 was the only Sid chip version that makes it possible to mix the oscillators (in any wav form combination) together, giving greater versatility and sound options. The 8580 also has the redesigned and much improved analogue Filters, as well as reduced noise output. There were 7 version's of the sid chip in total, 8580 being the most rare and recent. When buying a C64 its all a matter of chance to what version sid is installed, as there is no external markings that identifies the model."
