Actually I probably would prefer them to stay at 0-127 because of midi
comatibility, but maybe this even wouldn't be necessary to unify...

There might very well be values that are useful to send but that are
not needed to be contained in a GUI object. For example in your
s-distortion the filename of the shaper array could come from outside.

I would prefer to keep things localized through $0-arguments as much as
possible. What are the areas, where global access is needed? I could
think of the following ones: 

* Persistance. Saving probably should be centralized as much as

* External control: After seeing some OSC patches, I'm very fond of
  the idea to use OSC for all communication outside the abstractions.
  Inside of them I think, normal send/receives would be enough, but
  OTOH once you start to do OSC, there might not be much need for it.

* More?

I could figure an approach where you have one highly reused
abstraction that would be used to wrap above points: 
 [r $0-somevalue-read]
 [persistance_and_control_wrapper $1] <= use $1 for all global actions
 [s $0-somevalue-write]
