Hi Oleg,
I always found the easiest way of testing what a keyboard could & couldn't do via midi , was to midi it up to a software sequencer,record button pushes, intro' endings etc then check the event list in the sequencer to see what controllers, program changes etc the keyboard transmitted .

One way of telling whether or not there's enough info sent by your keyboard to control bank, program changes , volumes etc
best wishes
Rikki
