Will S970 accept program changes?

[VilleGuy]

I am still in the newbie phase of working my Yamaha PSR S970, and I would greatly appreciate your advice on how I can get my arranger keyboard to do what I want.

I want to maintain a songlist on my iPad and with the touch of a finger have the songlist software find the desired style, registration or MIDI file on my S970 or thumb drive and instantly access correct settings (tempo, voices, etc.) for that song.

Is there any way I can get the S970 to do this, or will I need to get an S775 or S975? I've seen posts that say those arrangers can deal with "program changes" (I think that is the correct term for what I seek) but the S970 cannot.

I've had success sending program changes (just the patch in Gen MIDI)  as the MIDI standard defines them but that may not be what you seek.  I don't believe you can use a MIDI event to change registration (styles, parts,multipads etc) on the 970.
