Yes, I know it can do +1/-1, but can one button jump to Preset 023 and another jump to present 123, etc.?
Do you mean the switches in the midi controller? If so, you absolutely can, that's how I use my midi controller:
Each one of the switches on my MC8 activates that preset in the Core. If I press and hold the switch, it sends me to another bank in the MC8 where I can switch individual blocks in the Core on and off as needed:
Hope that helps!
