MSSIAH: MIDI cartridge for the Commodore 64

The MSSIAH is a MIDI cartridge for the Commodore 64.
It contains a suite of music applications that starts instantly as you insert the cartridge and start up the computer.
With these applications you can play the C64's audio circuit (SID) via MIDI or stand-alone with the internal sequencers.

MSSIAH is short for MIDI SID Software Integrated Applications and Hardware and means that the cartridge contains both software and hardware to midify the C64. Since they are integrated you won't need hard-to-get MIDI peripherals to hook it up to your synthesizer or sequencer.

Just plug in a MIDI cable and off you go!
