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

Hi All:
I recall that at one time there was a gnuradio block that interfaced to some
sort of physical tuning knob. I am wondering if anyone remembers this and has
some details?
My recollection was that the device was from the gaming world, but that it was
never that popular so support for it dropped several years ago.
Thanks in advance,
Kevin
