How to control PSR-E363 functions over MIDI-USB?

[Practical Senses]

Hi!
Is there any way to control/change PSR-E363 additional function (for example Harmony, Arpeggio type, turning Dual and Split on/off, etc.) over Midi-USB from PC? I can't find any Sy*** or CC messages in manual to do this.
Pressing "Function" button on keyboard all the time is rather boring
Thanks!

All you can do by MIDI is in the MIDI reference manual.

You can set the master volume, master tuning, reverb type and chorus type by sy***. You can start and stop the accompaniment if the clock is set to external. I'm afraid there is nothing more...
