A snippet to choke off or fade a note

[Orvillain]

This is a super non-musical and basic snippet that shows the very beginnings of how to learn to choke off notes. It uses a midi script processor, and does the following:

• Setup a variable container for a last event id value.
• On Note On - Ignore the incoming midi event
• On Note On - Create a new artificial event, and play a note on the synth. It forces the pitch to be midi note 60, and velocity to be 100.
• On Note On - store the new event id into the last event id variable.
• On Note Off - There are two options. The first is to just kill the note altogether using Synth.noteOffByEventId and feeding in our last event id variable. The second option is to add a volume fade by using Synth.addVolumeFade.

There is very little that is useful about this snippet, other than showing the very basics of how to intercept a note event and do something with it. It is essentially monophonic and if you played a chord, I doubt it would work properly. This is easily addressable by using an array as our last event storage container, and pushing the new event id over to it.

I just wanted to put this together for myself to look back on, but also for people who are completely new to Hise to have a reference in the future.
