Hi Nicola,

You're welcome! To me the RPi is just another device running Linux. And
if it runs Linux it can run JACK and some of my favorite software. I'm
sometimes baffled by the immense detour people are taking just to get 8
note polyphony out of the RPi for instance. Or using some real-time
effects. Or building a drum sequencer. All the stuff is already there!
But no, apparently they prefer to reinvent the wheel.

That's weird as it shouldn't make a difference? I did find that raising
JACK's rtprio even more (I'm now using 84) decreases the number of glitches.

At the moment, no. I don't have any experience with WiFi dongles and the
RPi. I should give it a try.

It sure does. I for one can't do without the Treble Booster though :)

Great idea! I've got a bricked tablet lying around too and supposedly it
can run Ubuntu too. Keep us posted on anything that comes out of this!
