OSCulator 3.0 is here!

[Jordon]

I used to be able to Duplicate (or split, I forget which) a button and invert one of the in/outs so that it would send a midi note when pressed and when released.
This was really good for being able to hold a button down to have an effect or parameter turn on, and the effect turn off again when the button is released.
But I can't seem to get that to happen in this version.
Is there a different way of achieving this now?

Great job.

Which later versions of MacOS are compatible with OSCulator 3.0?
Any plans for further development?
