I want to play a guitar through Modep LV2 simulators, live. Is it
practical to do this through a USB 3 device (like this

I am currently using a Pisound on a Raspberry Pi 4, and it is working
great. But it does use up all the gpio pins and I do not need its MIDI
facilities. I would like to be able to use other SBCs, also.
I have used one in the past, over a decade ago, and there was noticeable
latency. Have things improved?
During the pandemic I tested a lot of USB sound cards on Linux -
actually the Focusrite Scarlett Solo was one of the best in terms of
latency (and also in terms of interrupt timing jitter - this is crucial
when it comes to very low latency and high CPU load):

With the HiFiBerry GPIO caps I get an even better performance, both in
terms of latency and jitter.
Best,
Giso
