Hi Steve,

I assume that the PSR keyboard's built in harmonizer on/off function is controled via a 'standard midi message', not a sysEx (system exclusive) command, right? If so, can you please provide the following MFC10 parameter settings needed to make this work:

1) Mode: 'Function' or 'Program Change'
1) Status:
2) Data/Ctrl:
3) Bank MSB/Max:
4) Bank LSB/Min:
5) Toggle on-off:

Thanks,

- Scott
