Reversing Sensor Data
I want to use incoming pot data to decrease gain on one channel and increase gain on the other. How would I do this? I tried an inverse scale, but that didn’t seem to work. Any thoughts?

I’m not sure how this would work. I’m trying to take serial data received from a potentiometer.
could you show some of your data then? Otherwise we’ll just be guessing, really.
The data that is feeding in is a number in a range from 0 – 1023 which is converted from voltage. I run the data into Arduino2Max through an Analog input then out to my gain sliders. Hope that helps.
if you just want a simple linear relationship use "expr 1023 – $i1"
[!- 1023] is faster than both scale and expr.
Metamax:
Just used the (!-) object and it worked great. I ended up scaling the data numbers down to the max number I set for my various gains so the action went smoother from my perspective. Seemed to work great, thank you.
Note you’ll have a dip in volume in the middle; that’s the reason why I recommended m4l.bal1~ – it does a proper mix between the two.
I still think it’s the best approach, hehe.
