How do you change patches...

...on the Odytron?

Ah yes - this is a little different to all the other software versions.  This is because there are so many parameters, some of them are chosen by selecting red/yellow mode (ie orange / white). 
So turn function knob to Porta/Patch
Push knob so it's red (yellow = portamento)
turn Value knob to select patch number
short press value knob = load patch
long press value knob = save patch
Note:  the value knob can't be used to test a note when the Porta/Patch function is set to patch (red).
