?Which messages work?

I quite often use a constant sound to test some input, a good example might be the case where you have some sound passing into a peak detector, which is then pasted into the constant sound. ie ([InputSnd]L threshold: 0.5) true: (1) false: (0), thus being able to use the output of the constant sound to trigger some other sound. But it might be useful to use 2 conditions, eg ([InputSnd]L threshold: 0.5) and: [!Block]) ifTrue: [1] ifFalse: [0]

But I'm pretty sure that the ifTrue: ifFalse: message doesn't work inside the constantsounds field. Is there a list of which SmallTalk messages work inside a sounds field or is it just a case of trial and error.

You can get to a list of real time expressions by choosing Documentation from the File menu, and then click on the Expressions Quick Reference link.

You can use arithmetic in place of logical operations. In your case, you could use multiplication to perform the AND function.
