[chuck-users] how to mickey-mouse a 'switch' statement into chuck?

[Forrest Curo]

"Something more elaborate than branching on the value of a specific
variable?"

To use a text keyboard to trigger real-time changes in key, mode ('major',
'minor', etc), record-&-repeat-&-vary (by scale degrees in whichever the
current  key & mode are), accelerate or slow playback, change target
instrument for playback-and/or-midi-keyboard, dump or keep current loop,
etc:
with some 36+ keys available for whatever organization of this works --
and I want to be able to modify the arrangement meanwhile so I don't trap
myself into a bad design...

so running the text input through a maze of logic by ascii values seems too
cumbersome.
I know, I could search-&-replace, but finding a key value in a list
and changing the associated function
just seems a whole lot less ugly!
-------------------------

Um, I'm now trying to install 'tap-plugins' as a prerequisite for
installing 'lick' -- and the instructions for that are telling me, ~'just
cd into folder and run 'make' -- but make can't find anything _to_ make! Do
I really need those plugins to install & use lick?
