At one time I controlled a voice harmonizer with my Kn7000. I set the Kn7000 to send the midi message on midi channel 5. Then I set the harmonizer to receive the midi message on channel 5. The same method is used for all other things you want to control.

Example:
My left hand triggers the chord on the keyboard going through a song. With a midi controller or another keyboard I would have to send and receive on the same channel. You set the channel and then save the changes you have made. You need the manuals for each unit you use. You are looking for a Midi Implementing Chart for both instruments; this will give you the send and receive information you will need.

Now that sounds pretty easy – but it gets a bit complicated when you are trying to control many different areas. I suggest you get a book on what Midi is about.

There are 16 midi channels; each channel has many, many areas that have a control numbers. Vibrato, cut-off, and the list goes on.

Hope this helps, John C.
