Hello fellows,

I am planning to build a DIY midi foot switch to control my sy 300. I need just a patch up an down butons, so I can use the three ctrl butons on the unity for switch effects.

My questions: is possible to do it with the standard midi messages like programm change or control change? Or do I have to use Sysex messages? And what are the messages for this specific function?

I will do it on a teensy 3.2 board wich is compatible with arduino programming. I have some experience on it and already did a controler for my GR-55.

Any help is very welcome!

Cheers

Ordinary midi patch change will do it.
For up/down, you just need to remember the previous patch number, and
change it +1 or -1.

There is also the External CTL plug in the back of the SY-300, so you could use two momentary foot switches assigned to do patch up/down.
