I would like to make a composition similar to that I made with quartz composer here:
quartz composer + ableton midi test
(ableton enable the sprites via midi out (notes on/off > sprite on/off)
I make this with vuo:
Vuo Midi test
but i have two questions:
- for enabling/disabling the square, i used a workaround scaling to 0 (isnoteon > convert to integer > scale).
what are other ways of doing the same thing?
- in my example all notes trigger a single square.
how to extract the notes in order to associate a single note to a single square?
I’m not sure if it’s somehow bad practice to feed an empty object to the renderer
Feeding an empty object to
Render Scene to Window/Image is OK.
(If it behaves oddly, it’s a bug and we’d like to know about it. :^] )
As @mnstri said, using
Select Input to toggle between the presence and absence of an object is a good practice.
If you’d only like to respond to certain MIDI notes, you could use the
Filter MIDI Note node — that node will only pass the MIDI note events that match the criteria you specify.
ok. all works perfectly now. this is the png of my composition (video very soon):
VUO + Ableton Live
thank you all!
