The Script gives you a file dialog and asks you to select one sample out of the folder. It computes nbrFiles using:

filesInSameFolder := fileName fileNamesOfSameTypeInSameFolder.

In the Sound itself, there's a SoundToGlobalController that generates a random index named !RandIndex that can be shared by all modules in the Sound.

((1 triggerTimeToNext: !DurOfNext s) nextRandom abs * ?nbrFiles) truncated + 1

Where does !DurOfNext come from? It is generated by the other SoundToGlobalController using the expression:

!RandIndex of: ?durations

Where does the variable ?durations come from? It is an Array computed and passed in from the Script using the Smalltalk expression:

(filesInSameFolder collect: [:sf | sf sampleFileDuration removeUnits]).

Multisample is the only part of this Sound actually generating an audio signal. It is triggered by:

1 triggerTimeToNext: !DurOfNext s

and selects which file to play using the generated !RandIndex

This is the first I've ever heard of this one - I could have used it a year ago...

Is there an up to date, comprehensive list of such gems? I tried searching Twiki and found nothing about it. (Other than this same thread.)

Best way to see the most up to date list is to type Ctrl+Shift+H in a parameter field.

Holding down the mouse button and scrolling through a pull down menu while trying to figure out what an expression does is the best way to do this???

(btw - I just did this and found lots of expressions I'd never heard of...)

what about this one..

neg: zero: pos: initially:

or intoSorted:

!!

a built in help with examples that can be compiled a la PD/SuperCollider is the best way to keep track of recent additions to the CapyTalk / SmallTalk code
