MIDI file in a Zip archive, 4 KB

A MIDI file for the Edirol PCR Series Keyboard to control DJ-1800.

Requires the Edirol PCR Editor application to upload the file to the keyboard; install it from the software CD-ROM that came with your PCR keyboard.

MidiPipes to convert e.g. Pitch Wheel Messages from a MIDI keyboard to DJ-1800's Pitch Bend.

Highly experimental... Please read the Read Me document by all means!
Requires the application MidiPipe and an external MIDI controller with a Pitch Wheel (e.g. like the Edirol PCR).
