Hello everybody.
In the Assignable menu you can define interesting functions for controlling the PSR-SX900 with the 6 assignable buttons and save them in the registration. I would like to control these 6 assignable buttons with an external footswitch controller software via the midi interface with (Sysex) commands. I couldn't find any corresponding tab control commands in the data list. Are there any undocumented (sysex) commands for controlling the tabs in general and specifically for the assignable tabs?
I found Sysex commands in the data list (Section Control) with which the style can be controlled directly. So for example, "FILL IN AA" can be started using a sysex command F0437E00107FF7. This makes it possible to control the style via the MIDI interface with the external footswitch controller software and the corresponding Sysex command. However, most of the functions that can be assigned with the assignable buttons as sysex commands are missing. For example switching the Vocal Harmony on and off and the assignable buttons. Are there undocumented sysex commands for this?
I am grateful for any help.
Thomas
