Hi it worked out well although for lack of time (it was just a sketch for a bigger project) i didn t create an Gem abstraction but i duplicated the object 16 times. Thanks SImone

After a few months without PD it seems like i forgot the basics and got stuck with something rather simple: I am using the NOTEIN object to track 16 coming from a sequencer, what i want to achieve is to toogle 2 different colors on 16 GEM objects ie: Note On - Note 60 = object 60 turns blue Note Off - Note 60 = object 60 turns white

Note On - Note 61 = object 61 turns blue Note Off - Note 61 = object 61 turns white

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
