Triple sensors - Kawai MP11 midi implementation

[Kurt W]

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.

I don't know if it will help, but check that you're running the newest software on the MP11. One of the updates did have something to do with the processing of MIDI ON and OFF.

I have contacted Clavia support and hope they can comment. Also will update my MP11 to latest 1.16 firmware and test again, thanks for your tip!

p.s. -- those CP4 figures, with a Note Off event immediately after each Note On, would indicate that it is not true that the CP4 is "retriggering from the lower sensor."

Actually I think you are correct, the CP4 is a dual sensor not triple sensor keyboard. Nowhere in the specs or documentation it is stated that it is triple sensor. My fault!

 

However the first sensor is obviously placed rather deep since retriggeting is quite easy, but the damper is activated after each key return. The Kawai gives a very different respons with the tone sustainng through the retriggering.
