Re: Gnuradio Interface to a Tuning Knob?

[Derek Kozel]

Hi Kevin,

Yes, I have one of these knobs, a Griffin PowerMate. There was support 
for it in the WX GUI on Linux, so it's supported in 3.7 releases.
https://github.com/gnuradio/gnuradio/blob/maint-3.7/gr-wxgui/python/wxgui/powermate.py

There was a longstanding kernel bug that ignored the 0 index step. A 
fairly minor issue but I don't know if was fixed in newer kernels.

I'd love to see someone use MIDI controllers in a GNU Radio based 
application.

Cheers,
Derek
