Transmitted in any conditions of performances.
Sync Mode: MIDI
Not transmitted.
●Start
Status
FAH
* Not transmitted in case that Sync Mode value is “MIDI.”

●Stop
Status
FCH
* Not transmitted in case that Sync Mode value is “MIDI.”
●Active Sensing
Status
FEH
* Transmitted at approximately 200 msec intervals. It is possible to find out MIDI line
trouble by checking arrival Active Sensing message for the device connected with MIDI
OUT.

* MIDI Channel Number is same as drum part channel.
* Not recognized in case that drum part channel is “OFF.”
* Recognizing Program Change message, DR-670 switches Drum Kit of the same number
as Program Number. Consequently, bass tone changes as the Drum kit including.
* After recognizing a Program Change message, new voices will sound as a switch, but
sounding voices will not change then.
