Hello,

I found this patcher and use it. what means [zl group 3] and why [prepend xyc] ? The first I think has to do with length of string of data...

If anyone can help me ?

[iter] spits out each number of the list sequentially.

[zl group 3] makes groups of 3 consecutive elements.

"xyc x_value y_value curve_value" message to [function] sets points and a curve factor.
