Kawai Synthesizers

Hello,


  I recently got a Kawai K1M and am currently trying to write an 
editor program for it.  I use a Music Quest MPU401 interface and Turbo 
C language with Windows 98.


  


  I can send a One_Single_Internal_Voice message with the 86 
S_parameters from the PC to the K1M, but the K1M will not update any 
of the old parameter values to a new sound unless I press the 
Single/I-iE-e button on the actual K1 twice.  




  I've checked the checksum and I believe that it is correct.




  The MIDI message that I'm sending to the K1 is (hex):


   F0 40  00  20  00 03 00 00 .. 86 S_params  ... checksum .. F7




  for Int A-1 voice as I just want to get something very elementary


working first before expanding to more versatile editor program.




  I would be happy to share my source code for anyone who may still be 
interested in synth Kawai programming.  Turbo C is now free ware from 
Borland and easily downloadable.




  Might anyone have any suggestions for making a K1 editor work?




Thank you,


Alan Probandt
