MIDIjoy interface

MIDIjoy is a software+interface combination that allows you to use your Atari or Commodore homecomputer as a musical instrument. the idea is based on the Atari 2600-PC-Interface created by Sebastian Tomczak and was expanded to suit the extended capabilities of the 8-Bit homecomputers. the interface emulates a USB-MIDI (serial MIDI is optional) device that can be accessed by any kind of instrument as well as sequencer software on a PC or Mac that can output MIDI data (e.g. Ableton Live or Aria Maestosa). the MIDIjoy software receives this data from the interface via the joystick ports and plays them on the POKEY (or SID or TIA) sound-chip. in contrast to most SIO-based MIDI interfaces, a MIDIjoy-driven Atari can be used as a live instrument in real time with up to four sound channels simultaneously. at the same time, all POKEY parameters (AUDCTL, AUDC1-4) can be changed on-the-fly as well as activation of ADSR envelopes. music input can be recorded and saved to disk for later usage - ev
