Try something like this:
[notein 16] <- assuming you read from channel 16
| |
[pack 0 0] <-- pack note number and note velocity into a list
|
[route 60 61 62 ...] <-- route according to note number
|
[> 0]
|
[select 1 0] <-- check if noteon or noteoff was sent.
| |
[blue( [white(
If you use an abstraction for your Gem objects, I would put the
route-logic into that abstraction like:
[r NOTE] <-- "pack"ed note/velocity pairs
|
[route $1] <-- create abstraction with arguments like 60, 61 ...
|
[> 0]
|
[select 1 0]
| |
[0 1 0( [1 1 1(
|________/
[color]
|
[square]
Ciao
