GLT (Grain Life-Time) MIDI Trigger

[phase ghost]

Hi All,

I'm demoing Crusher-X at the moment (in Ableton). I'm able to spawn a new generator with a MIDI keyboard press. However, I'd like to limit that a single note (C 60 for example). But, I'm not sure how I'd achieve that. The manual states the following:

Once the count-down timer has expired the attached generator is deactivated until one of the following events occur:
...
A MIDI-Note On event (or a fixed MIDI-Note On state)

Which is working. But, I'm not sure how to limit that generator activation to a single note. I opened up the MACRO Map panel, but I can't seem to save a mapping in demo mode. Is there a global setting that handles this perhaps? Or do generators spawn no matter the MIDI note that's pressed?
