I'm quite new to Max, but I've been trying for weeks to get a physical xy controller to map in ableton then send via OSC to Reaper to control the ATK toolkit transform.

I've been given varying answers, with Atan2, also the correct maths but nothing I do with these equations relate the xy to the azi distance in the ATK toolkit plugin.

I've taken y and x, processed by atan2 to get Azi. Then I've taken x, scaled that from 0. 1. to -1.1, performed the math Expr sqrt ($f1*$f1 + $f2*$f2), then scaled the output from 0.5 1 to 0. 1. This means that the centre is 0 of the xy and the edges are 1. But azi and distance don't work together and the pluing just wildy spins around, also I need some way to get 180 degress to - 180 degrees smoothly.

I thought this would be simple but It's taking every day of my life!..

I've had one performance already but I'd love to add more physical control over my sounds.

Thanks, tried that, doesn't work. Works for target plugins that have y / x in ambisonic terms

I used ATAN2 / pi * 180 and then scaled that to 1. 0.

but now I have to turn my xy pad once to the left to get it to relate to the correct orientation, what's happened here?

Ok I got it with some help from Bruce Wiggins.

reverse input of y and x to the ATAN2 then invert x value to get the correct orientation.
