Before you begin recording data, make certain that the MIDI Thru function in your sequencer is set on. Before we begin recording, we need to discuss Auto Channelize. Many sequencers, including the MC-50MkII, require that you transmit your performance on the same MIDI channel that you wish the sequencer to play back. This means that you will need to change the BASIC channel to match the MIDI channel of the selected Part for each track. Many computer software sequencers have the ability to re-channelize the incoming data to any MIDI channel you select. This function is typically called Keyboard Thru or Auto Channelize. Throughout the remainder of this guide, we will assume that your sequencer does not re-channelize incoming MIDI messages. For this reason, we will do most of our sequencing work from the SYSTEM MIDI menu.


1. Press SYSTEM, then press PARAMETER NEXT twice to access the MIDI display screen.
2. Press ENTER to access the BASIC MIDI channel. If it is not already set to 2, use the VALUE buttons and make it so.
3. Play your guitar, and you should hear the Part that you assigned to MIDI channel 2 earlier in this guide. Start recording your first track into your sequencer and it should record and play back your data.
4. Use the VALUE buttons to select the MIDI channel that you want to record your next track on. Part 2 of the GR-1's sound source should be set to MIDI channel 3, Part 3 should be set to MIDI channel 4, and Part R is on MIDI channel 10. If they are not set this way, review pages 2-4 to make the appropriate adjustments.

If you are using a computer-based sequencer, typically you will have Keyboard Thru or Auto Channelize. If that is the case, then you simply need to change the MIDI channel of the track on which you are recording to channels 2,3,4 and 10. Consult your sequencer's owners manual for more information.

5. Record onto track 2 of your sequencer. While you are recording, you should be hearing track 1 of the sequencer playing back Part 1 of the GR-1. The track you are recording should be playing Part 2 of the GR-1.

6. Repeat the last two steps to record onto track 3 on MIDI channel 4.
7. If you want to record a drum Part, set the external transmit channel on the GR-1 to 10.
8. Record your percussion Parts into the sequencer.

It is recommended that you insert MIDI bank and program changes at the beginning of a sequence so the correct sounds are recalled when loading and playing back sequences. Consult the owner's manual of your sequencer to find out how to do this.
