I want to play a guitar through Modep LV2 simulators, live. Is it practical to do this through a USB 3 device (like this https://focusrite.com/en/audio-interface/scarlett/scarlett-solo)?
Should be no problem. It's less practical though I think because you have to deal with an extra cable that could come loose. And I think the chance of running into interference issues could become bigger.
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?
Yes. Not only on the USB side of things but a Pi 4 is also way more performant then a Pi 1. And already a decade ago latency was acceptable with a Pi 1 and a USB interface, I was pioneering around 2013 with a Pi 1 and an Edirol UA-25 with 8ms system latency. Pi 1 was running Guitarix and I had a Boss FC-50 hooked up to switch between effects (echo, chorus, distortion). Worked pretty well actually.
Best, Jeremy
