Other Tone Parameters
Now that we have learned how to choose sounds for each Part from the GR-1’s front panel and from an external
sequencer, let’s look at the other parameters that can be set up from the EDIT RECORDER/PART menus.
1) Press EDIT RECORDER/PART. Then press PARAMETER PREVIOUS twice to access PART SET.
2) Press ENTER. Within this menu, parameters are available for all three instrument Parts plus the rhythm Part.
This screen allows us to work with PART 1:
38
REV
EDIT
MUTE CHO
PART 1->
3) Using the
PARAMETER
buttons, scroll between the 3 instrument Parts and the parameter menus for the
DRUM
Part. Call up
PART 1
and press the
ENTER
button again to access individual parameters for the Part. Use the
VALUE INC and DEC buttons to alter values. Here is a list of the available parameters with a brief definition:
P1VOL
: This sets the volume level of the Part. You can also send MIDI continuous controller number 7 from
your sequencer to alter this parameter setting in real time.
P1CH
: This assigns the Part MIDI channel. The Part can be set to
1
through
16
or
OFF
. Be sure to assign each
Part in your multitimbral system to its own MIDI channel. In the “Recording the Multitimbral Parts” tutorial later
in this guide, we will need the three instrument Parts assigned to MIDI channels
2
,
3
&
4
.
Note: When the GR-1 is in MONO mode it is possible to conflict with the MIDI channel settings of each Part.
For example, if we set the BASIC channel to 1 in MONO mode we will use up channels 1-6 conflicting with any
of the Parts set on MIDI channels 1-6.
P1REV
: This adjusts the reverb level of the Part. You can also send MIDI continuous controller number 91
from your sequencer to alter this parameter setting in real time.
P1CHO
: This adjusts the chorus level of the Part. You can also send MIDI continuous controller number 93
from your sequencer to alter this parameter setting in real time.
P1BND
: Bend Range is a very important parameter for accurate tracking with MIDI Guitars.
0
to
24
are valid
settings, with
12
being the most common.
P1PAN
: This parameter sets the stereo panning of the Part to between
<63(Left)
,
63>(right)
&
RANDOM
. You can
also send MIDI continuous controller number 10 from your sequencer to alter this setting in real time.
There are also parameters designed to set-up the Rhythm/Drum Part.
1) Press the
EXIT
button one time, then use the
PARAMETER
buttons to scroll through Drum Part Parameters.
These parameters are the same as the ones in the Part parameters.
2) Press the
PARAMETER
buttons to call up DR-CH. MIDI channel
10
is the industry standard for drums and it is
strongly recommended that you keep your drum Part set there.
III. Recording The Multitimbral Parts
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
