Using the SonicCell in Patch Mode
Matrix Control
Ordinarily, if you wanted to change tone parameters using an external MIDI device, you would need to send System Exclusive
messages-MIDI messages designed exclusively for the SonicCell. However, System Exclusive messages tend to be complicated, and
the amount of data that needs to be transmitted can get quite large.
For that reason, a number of the more typical of the SonicCell’s tone parameters have been designed so they accept the use of
Control Change (or other) MIDI messages for the purpose of making changes in their values. This provides you with a variety of
means of changing the way patches are played. For example, you can use the Pitch Bend lever to change the LFO cycle rate, or use
the keyboard’s touch to open and close a filter.
The function which allows you use MIDI messages to make these changes in realtime to the tone parameters is called the “Matrix
Control.” Up to four Matrix Controls can be used in a single patch.
To use the Matrix Control, specify which MIDI message (Src) will be used to control which parameter (Dest), and how greatly (Sns),
and the tone to which the effect is applied (Tone).
Settings for matrix control (Patch Mtrx Ctrl1–4 screens)
Parameter
Value Explanation
Src
(Control Source)
Sets the MIDI message used to change the tone parameter with the Matrix Control.
OFF:
Matrix control will not be used.
CC01–31, 33–95:
Controller numbers 1–31, 33–95
PITCH BEND:
Pitch Bend
AFTERTOUCH:
Aftertouch
SYS CTRL1–4:
MIDI messages used as common matrix controls.
VELOCITY:
Velocity (pressure you press a key with)
KEYFOLLOW:
Keyfollow (keyboard position with C4 as 0)
TEMPO:
The system tempo (p. 177) or the tempo of an external MIDI sequencer.
LFO1:
LFO 1
LFO2:
LFO 2
PITCH ENV:
Pitch envelope
TVF ENV:
TVF envelope
TVA ENV:
TVA envelope
For more information about Control Change messages, please refer to “MIDI Implementation” (p.
246).
Velocity and Keyfollow correspond to Note messages.
Although there are no MIDI messages for LFO 1 through TVA Envelope, they can be used as Matrix
Control. In this case, you can change the tone settings in realtime by playing patches.
• If you want to use common controllers for the entire SonicCell, select “SYS CTRL1”–”SYS
CTRL4.” MIDI messages used as System Control 1–4 are set with the Src1–4 (p. 179).
There are parameters that determine whether or not Pitch Bend, Controller Number 11 (Expression)
and Controller Number 64 (Hold 1) are received (p. 114). When these settings are “ON,” and the
MIDI messages are received, then when any change is made in the settings of the desired
parameter, the Pitch Bend, Expression, and Hold 1 settings also change simultaneously. If you want
to change the targeted parameters only, then set these to “OFF.”
• There are parameters that let you specify whether specific MIDI messages will be received for
each channel in a performance (p. 72). When a patch with Matrix Control settings is assigned
to a part, confirm that any MIDI messages used for the Matrix Control will be received. If the
SonicCell is set up such that reception of MIDI messages is disabled, then the Matrix Control will
not function.
