Hi Josh,

The "t" is an abbreviation for "trigger". You might want to check out the help file for [trigger].

Basically, computers are dumb animals, and need to be told exactly what to do and in what order, or else they get confused and don't do things the way you expect. [trigger] is a message sequencer which says "first do this, then do this, then do this" in a right-to-left order.

The "f" and the "b" stand for "float" (a floating point number, ie. a number with a decimal place) and "bang" (a message which many objects interpret as "do this action now").In PD-speak, these are known as "creation arguments" (extra information used when the object [trigger] is created).

So, whenever [trigger] gets an input, it outputs things in this right-to-left order.

If [trigger bang bang float] (or [t b b f] for short) gets the message "5" (a float), then it would output the following, in order:

5 bang bang

Bangs are often used when dealing with "hot" and "cold" inlets. Check the manual.

I've written a bit more about it in this tutorial:

(Slightly unfinished, but in the works...)

Otherwise, the HTML PD manual and the Control Examples patches in PD (keywords = order of operations, hot and cold inlets) explain it as well.

best, d.

hello all,

spending some time tonight downloading patches and messing with them in an attempt to learn something. I'm seeing a few instances of something that looks like this:

t b b f

or something to that effect. can someone shed some light on what this does?
