I'm trying to understand some of the math functions in PureData.

What I want to do is be able to toggle between three octaves of the same frequency range.
Approximately
130 - 164
260 - 328
520 - 656
I want to use a panning knob to move around in these frequencies. With a bang I want to be able to change between these ranges. How do I do this with the math functions?

THANK YOU THANK YOU THANK YOU

Hi,

Here are two options, one using [multiplex], the other using only a complex [expr]. If you need help understanding the patch, just let me know:

And here is the patch: Untitled-1.pd

I hope this helps, take care,
