Recognized Receive Data
■ System Realtime Messages
● Status
FEH
* By receiving an Active Sensing message, the PK-9 enters
the mode timing the interval between incoming MIDI
messages. If the interval exceeds 500ms, the PK-9 trans-
mits Note Off messages corresponding to the transmitted
notes being On, and returns from this mode.
■ System Exclusive messages
Data Set 1 (DT1) is the only System Exclusive messages
received by the PK-9.
● Data set 1 DT1 (12H)
Address of parameter groups
■ All other messages received
The messages received via MIDI IN are mixed (“merged”)
with the PK-9’s MIDI messages and transmitted via MIDI
OUT (“Soft Thru” function).
