Do you mean you could run a regular jack app on bela?

About the low latency audio on regular linux, I know it's possible.
I've been able to run my onboard soundcard at 16/2 48000 with no xruns
on my old laptop (core2duo 2GHz). It starts to drop frames as soon as
you do anything non-trivial, though.

When I need live monitoring, I set up the card at 128 frames. That is
low enough I can play guitar or keys normally.

About the RT kernel, yes, it makes a world of a difference on my old
computers at the lowest latencies.

I also have a stock kernel configured for low power consumption on my
netbook, and at 1024 frames I could build a quite big patch on
automatonism yesterday, and play for hours without xruns.

BTW check out automatonism, it's a great modular synth for puredata:
