I am using the -rt option but encounter DIO errors on editing larger tables like the original poster, on Archlinux with realtime kernel and Jack in mild low latency conditions, 16ms. No Xruns, just the DIO. But when I use Alsa as backend it gets better!
A modern system should be able to handle multimedia like video and 3D plus GUI without interrupts in the audio stream. The separation from Backend and GUI Frontend in PD is leaving a bit to desire and my question if its possible to solve this, in maybe 10 years or so? Or will the new thread object help?
Anyway, PD was the star in my lecture about Linux Audio yesterday, resulting in the most interest and questions.
Cheers,
Malte
