Yeah I tried that out a few months ago when we started the thread. Jack adds some unnecessary overhead in my opinion and I'm surprised that a device that should be more than capable to handle this is just not setup correctly. I'm running a minimal commandline install and pd + realtime & straight alsa should work great ... it has for me in the past.
His jack setup basically uses *all* the cpu of the pi, so that cuts out the other parts of my setup altogether .. visual, device input, etc. Again, I was able to get good latency with a much lower resource machine (until it just wore out), so it *should* be possible.
