controlling Python script with usb midi controller tia sal22

[Rick T]

Greetings All

I have a usb midi controller (uc-33e) and I have a working python
script see below. I would like to be able to control the variables of
the python script using my usb controller does anyone have an example
of this? I would like to use the "midi learn" function to
automatically map a midi control to an object (like in Ardour which is
a music program for linux) by ctrl-middle clicking the object and just
turning the control on the usb midi controller to map it. But I'm also
willing to hard code the midi CC into the python script if needed.

I'm using linux 64bit ubuntu

here's a link to the code below:
