Connecting the GR-0 to a Sequencer
On the Sequencer Side of Things
To connect your sequencer to the GR-20, the sequencer has to have a MIDI
IN jack and a MIDI OUT jack. If you’re using a:
hardware, standalone sequencer—you’ll typically find a MIDI IN jack and
a MIDI OUT jack on its rear panel.
keyboard workstation—you’ll typically find a MIDI IN jack and a MIDI
OUT jack on its rear panel.
sequencing program on a computer—MIDI connectivity has to be added
to the computer in either of two ways. You can use a:
MIDI interface —which is usually a rack-mounted or tabletop box
that connects to the computer via USB or FireWire, and provides
MIDI ports you can connect to your other MIDI devices.
sound card—that offers MIDI jacks, or a game port to which you
connect a special cable that provides MIDI jacks.
On the GR-0 Side of Things
Using a MIDI cable:
Connect the GR-20’s MIDI OUT jack to the sequencer’s
MIDI IN jack.
Connect the sequencer’s MIDI OUT jack to the GR-20’s
MIDI IN jack.
If you don’t intend to use the GR-20’s own sounds, you don’t
need to connect the sequencer’s MIDI OUT jack to the GR-20’s
MIDI IN jack.

Preparing the GR-0 for Sequencing
MIDI Channel
Select the basic MIDI channel on which you want the GR-20 to send and
receive data. (As we’ll see, this channel also acts as the first channel the
GR-20 uses in its Mono transmission mode.)
Unless you have a MIDI system that provides each MIDI device its own
set of 16 MIDI channels, select a channel no other device is using.
To set the GR-20’s basic MIDI channel:
Press SYSTEM EDIT repeatedly until the MIDI CH indicator lights.
Turn the Number/Value dial to select a basic MIDI channel, from 1-11.
Press EXIT—the GR-20 stores your settings.
Local Off
When you’re using a GR-20 patch while sequencing, notes can play twice:
once from your guitar, and once more from the output of your sequencer.
SEQUENCER
1 The guitar plays the GR-20 note.
2 The GR-20 sends a note event to the sequencer via MIDI.
3 The sequencer plays the GR-20 note again.
