MIDI Data Format

This section explains the format of the data that the CL series is able
to understand, send, and receive.
1 CHANNEL MESSAGE
1.1 NOTE OFF
Reception
These messages are echoed to MIDI OUT if [OTHER COMMAND ECHO] is ON.
They are received if [Rx CH] matches, and used to control effects.

1.2 NOTE ON
Reception
These messages are echoed to MIDI OUT if [OTHER COMMAND ECHO] is ON.
They are received if [Rx CH] matches, and used to control effects.

1.3 CONTROL CHANGE
Two types of CONTROL CHANGE can be transmitted and received; [NRPN] (Non-
Registered Parameter Numbers) and freely-assigned [TABLE] (1CH x 110) messages.
Select either [TABLE] or [NRPN].
Reception
These messages are echoed to MIDI OUT if [CONTROL CHANGE ECHO] is ON.
If [TABLE] is selected, these messages are received when [CONTROL CHANGE Rx] is
ON and [Rx CH] matches, and will control parameters according to the settings of the
[CONTROL CHANGE EVENT LIST]. For the parameters that can be assigned, refer
to "Parameters that can be assigned to control changes" on
If [NRPN] is selected, these messages are received when [CONTROL CHANGE Rx] is
ON and the [Rx CH] matches; the four messages NRPN control number (62h, 63h) and
DATA ENTRY control number (06h, 26h) are used to control the specified parameter.
Transmission
If [TABLE] is selected, and if [CONTROL CHANGE Tx] is ON when you operate a
parameter that is assigned in the [CONTROL CHANGE EVENT LIST], these
messages will be transmitted on the [Tx CH] channel. For the parameters that can be
assigned, refer to "Parameters that can be assigned to control
If [NRPN] is selected, and if [CONTROL CHANGE Tx] is ON when you operate a
specified parameter, the four messages NRPN control number (62h, 63h) and DATA
ENTRY control number (06h, 26h) are transmitted on the [Tx CH] channel. For the
parameters that can be assigned, refer to "Parameters that can be assigned to control
changes" on page 232.
CONTROL CHANGE messages are not used for transmission to CL Editor because
there is no guarantee that the contents of the assignment tables will match.
(PARAMETER CHANGE messages are always used.)
CONTROL CHANGE numbers 0 and 32 are for selecting banks.

curValue = paramSteps * add + mod / 2;

whether or not the status byte is omitted.
1.4 PROGRAM CHANGE
Reception
If [PROGRAM CHANGE ECHO] is ON, bank select messages will also be echoed
from MIDI OUT.
If SINGLE CH is selected, these messages are received if [PROGRAM CHANGE Rx] is
ON and the [Rx CH] matches. However if [OMNI] is ON, these messages are received
regardless of the channel. When these messages are received, scene memory, effect
librarya nd premium rack library are recalled according to the settings of the
[PROGRAM CHANGE EVENT LIST].
Transmission
If [PROGRAM CHANGE Tx] is ON, these messages are transmitted according to the
[PROGRAM CHANGE Table] settings when scene memory, effect library and
premium rack library are recalled.
If SINGLE CH is selected, these messages are transmitted on the [Tx CH] channel.
If the recalled scene memory, effect library and premium rack library has been assigned
to more than one PROGRAM NUMBER, the lowest-numbered PROGRAM NUMBER
for each MIDI channel will be transmitted.
PROGRAM CHANGE messages are not used for transmission to CL Editor because
there is no guarantee that the contents of the assignment tables will match.
(PARAMETER CHANGE messages are always used.)
You can choose either MULTI MIDI CH or SINGLE CH.
If SINGLE is selected
You can choose the Rx CH, OMNI CH, and Tx CH.
You can choose whether a bank select message will be added.
A bank of up to 16 can be specified.
If MULTI is selected
The Rx and Tx channels will be the same.
The assignment table will use the settings for each MIDI channel. Bank select messages
will not be added.
You can make settings for up to sixteen MIDI channels.
