* Reception is always “omni on” in the record mode.

(Reception)

* When the Utility mode PGC MODE parameter is set to NORMAL.

When n ≠ 9 in the play mode or when the record track is not set to Dr in the record mode.

The voice is changed when p = 0 … 107.
The voice is turned off when p = 108 … 127.

When n = 9 in the play mode or when the record track is set to Dr in the record mode.

p = 0 … 99 ignored.
The voice is changed when p = 100 … 107.
The voice is turned off when p = 108 … 127.

* When the Utility mode PGC MODE parameter is set to GM.

When n ≠ 9 in the play mode or when the record track is not set to Dr in the record mode.

The voice is changed when p = 0 … 127.

The received data is assumed to be GM-format data, and appropriate voices are selected.
If no appropriate voice is available, the voice is turned off.

STATUS 11111110 (FEH)

Transmitted once approximately every 175 milliseconds.

Sensing is initiated the first time this code is received. If no status or data core is received
for more than about 350 milliseconds, the MIDI receive buffer is cleared and all current notes
and the sustain switch are forced off. Also, all control values are reset.
