Can I control a pgm change on an SPX90II from qu16 and hence from mixing station?

Hi There,

I would like to be able to change the program on an SPX90II, used as an external effect from an aux, at the very least from the desk itself, but ideally from an iPad using Mixing Station. Is this possible?

Any one have any thoughts?
Thanks

Or should I use some Bluetooth to Midi connection to control the SPX that way?
