The Midi module provides a software interface between the Music System
and an external midi keyboard/synthesizer. This module requires that a
MIDI keyboard is connected to your Commodore 64 microcomputer via a
hardware MIDI interface. AMS is configured to function correctly with most
MIDI keyboard/synthesizers in conjunction with either the S.I.E.L. MIDI
computer interface (UK, or the PASSPORT DESIGNS C64 MIDI INTER-
FACE (USA). Other MIDI hardware combinations (ie J.M.S.) may also work,
but Island Logic cannot guarantee this. You may also find it desirable to
provide some form of amplification for your keyboard.

Midi hardware combinations can send and receive MIDI format data files
from the Commodore 64. The AMS MIDI module can record and playback
MIDI standard files with a limit of six voices or channels. The module will
allow a single keyboard to be directly interfaced with AMS. For more
complex operations consult your MIDI hardware manual.
WARNING
During any sort of disk drive operation it is advisable to remove
the lead from the ‘MIDI IN’ socket of the interface. This is because some
keyboards could interrupt such operations and possibly crash the system.
The ‘MIDI IN’ lead should only be connected during MIDI RECORD and
PRACTICE operations.
