Reception Format
1. Note On
5. Active Sensing
This message is received on the MIDI channel specified
in the currently selected BANK when CONTROLLER
1
or CONTROLLER 2 is: assigned to «KEY
NOTE
or
«KEY VEL. When a NOTE ON message is received, the
value of the assigned effect parameter is changed accord-
ing to received the velocity value.
And, for programs of PI1 or PI2, this is received as mes-
sage to control pitch shift value. The velocity value is
ignored. Reception is not possible when the base KEY
parameter is OFF.

2. Control Change
This message is received on the MIDI channel specified
in the currently selected BANK when CONTROLLER
1
or CONTROLLER 2 is assigned to control number.
When a CONTROL CHANGE message is received, the
value of the assigned effect parameter is changed accord-
ing to the received control value.

3. Program Change
This message is received on the MIDI channel specified
in the currently selected BANK. When
a PROGRAM
CHANGE
message
is received,
the effect program
assigned to the received program number in the program
change assignment table of current BANK is selected.

. Channel Pressure
This message is received on the MIDI channel specified |
in the currently selected BANK when CONTROLLER
1
or CONTROLLER 2 is assigned to CHANNEL PRESS.
When a CHANNEL
PRESSURE
message is received,
the value of the assigned effect parameter is changed
according to the received pressure value.

After ACTIVE SENSING has been received, if the inter-
val time is more than 300 milli seconds, the MIDI volume
is set to maximum.

For programs of TDL or TMD, when the ТҮР parameter
is MIDI, the delay time is set to interval time of TIMING
CLOCK.
