Channel Message; Midi-Datenformat - Yamaha M7CL Bedienungsanleitung

In diesem Abschnitt wird das Datenformat beschrieben, das das M7CL interpretieren, senden
und empfangen kann.

1 CHANNEL MESSAGE

1.1 NOTE OFF
Reception
These messages are echoed to MIDI OUT if [OTHER 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 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 assign table]. For the parameters that can be assigned, refer to
"Parameter, die Controllern zugewiesen werden können" on page 245.
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 assign table], these messages will be
transmitted on the [Tx CH] channel. For the parameters that can be assigned,
refer to "Parameter, die Controllern zugewiesen werden können" on page 245.
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 "Parameter, die
Controllern zugewiesen werden können" on page 245.
Control Change messages are not used for transmission to M7CL 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.
