I would like to transform a phasor ramp into a triangle (with variable peak position) inside gen; I've browsed the gen examples folder and can't find anything. Any pointers?

there's a gen function/operator/thing called . . . . (drum roll) . . . . triangle. I just assumed that all we had in gen was phasor, and had to grok our own shapes.

That's funny, I wanted the same thing, then discovered the triangle object, but too late. Maybe it's newer. Anyway if you want to make other kinds of variable=peak things, here it is in basic objects without triangle:

You have a solution now, but in answer to your original question: the formula to convert a signal in the positive unit range (i.e., phasor~) to a triangle looks like

As it stands, the output of that formula only goes from 0 to 0.5, so you'd have to scale it if you want a unit range.

Since MSP doesn't have an [if~] object, it can be a bit fiddly to piece this together with [

the most optimal solution I have so far is in Godel, here is a screenshot. What it does is use a selector statement inside gen codebox to eliminate unnecessary processing, and I found this more efficient than using an if statement in gen codebox.

Also you will see some maths on the right operands of ternary operations, which also eliminates some processing overhead.

. . . and it appears I used the term "grok" incorrectly, my bad

triangle~ equation; never mind, solved
