Freezing a KeyPitch with trackAndHold

Question

Why does a Capytalk expression like "(!Freeze - 1) trackAndHold: !KeyNumber nn" inside a Frequency Parameter Field not work as expected? What I'm doing wrong?

I want to control the frequency of a sound with a keyboard and to freeze from time to time the currenty played frequency by pushing a button, and using the keyboard during this time for controlling other parameters without affecting the frequency (and continue playing with variable frequency after releasing the button again).

Answer 1

I think this will work if you do the difference in the opposite direction:

(1 - !Freeze trackAndHold: !KeyNumber) nn

It also works with a logical NOT,

(!Freeze not trackAndHold: !KeyNumber) nn

(This freezes on the last pitch but does not affect !KeyDowns)

Comments

For me "(!Freeze not trackAndHold: !KeyNumber) nn" is the best and most interesting solution. And of course toggle elements like these must be "(1 - !HotValue)" ... I've used this thousands of times ... don't know where my head was ...
