I've seen that you fulfilled my request about allowing globals to expression and i'm VERY grateful.

While I was enjoying this feature and struggling with programming some modifier, i thought: why can't we allow expressions in parameters?

if you print "50 * 2", you'll get a scale(100). If you print "50 * halfbeat", and halfbeat global is 10 you'll get scale(500).

I'm suggesting this implementation: you right-click on some modifier, i.e. scale and there's an option called "Make expression". You click it and your parameter field turns from number input (with up-down keys) to string input (like text, or expression parameter itself). Previous value stays in place. So, if you had "scale: 50", where 50 is number, you get "scale: 50" where 50 is expression. If you have your parameter as expression, "Make expression" option in context menu will turn to "Make numbebr"

x in expression would refer to previously caught value (like expression parameter itself).

This partially covers globals in parameters: viewtopic.php?t=1072 (except my suggestion of mapping parameters to any source).

I'm not sure what the difference is between that and just replacing the Scale modifier with an Expression modifier that says 50*x?

Maybe scale wasn't a good example and modifiers like "smooth" or "delay" would be better ones.

But yeah, a good point: I could actually implement most of modifiers in expression language.

I can't save any state, to implement smooth/delay/hold/etc., and, putting big one-liners in that small text field is a little bit painful.
But other than that, I may not need this feature that badly as I thought.
