Using patch change to select a song?

[deanspy]

Hi folks,

PSRSX-700 here. What I would like to do is send patch changes to select a particular style or song. I'm having trouble figuring out how to word the question to find this information.

I also wonder if there are midi commands that can do a fill, using a midi foot pedal for example.

I'm sure I read something somewhere that said this was possible, but my brain is fried.

Any help most appreciated.
