Midi preset

You can use the Cons (spreads) to Concentrate all values to 1 big IObox, use herr inspector to change the input count for that node. And use Stallone (spreads) to reverse that process.

Since the Nano does not have cool automated faders (like a BCF2000), you can not ´send´ values back. So you switch between the saved and the real values. The way I showed is doing the switching by last changed, but if you want you can make more complex rules.
