I am using a Kawai MP11 to play the pianos of a Nord Stage 3 Compact. When lifting the key slightly there is no problem to retrigger the internal Kawai piano but the NS3 does not respond. Decided to monitor the midi output from the MP11.
I play the key, hold for 3-4 seconds, retrigger the key 3 times and wait 6-7 seconds to finally release it:
12:09:25.323 [Note On] ch=1 note=60 velocity=87
12:09:28.809 [Note On] ch=1 note=60 velocity=19
12:09:29.179 [Note On] ch=1 note=60 velocity=26
12:09:29.690 [Note On] ch=1 note=60 velocity=18
12:09:36.650 [Note Off] ch=1 note=60 velocity=87
12:09:36.651 [Note Off] ch=1 note=60 velocity=87
12:09:36.652 [Note Off] ch=1 note=60 velocity=87
12:09:36.653 [Note Off] ch=1 note=60 velocity=87
Strangely the Kawai waits to send any note off until the final relase. But should the Nord still trigger on the four consecutive note ons? No rules or specifications how to handle this?
This made me curious, tested with a Yamaha CP4 which works as expected with the NS3, retriggering from the lower sensor plays the Nord:
13:17:12.569 [Note On] ch=1 note=60 velocity=98
13:17:16.480 [Note On] ch=1 note=60 velocity=0
13:17:16.545 [Note On] ch=1 note=60 velocity=36
13:17:16.992 [Note On] ch=1 note=60 velocity=0
13:17:17.106 [Note On] ch=1 note=60 velocity=23
13:17:17.517 [Note On] ch=1 note=60 velocity=0
13:17:17.715 [Note On] ch=1 note=60 velocity=53
13:17:24.677 [Note On] ch=1 note=60 velocity=0
The CP4 sends note off (velocity=0) per triggering. This should indicate that the Kawai has troublesome implementation.
