I implemented a lock-free logger in my fork that i use for instance to report the DSP scheduling step by step.

I have catch the problem while testing edge cases.

This seems to fix teh problem. I don't know how you or anyone (myself included) can understand how that code works...

IMHO it does not properly shift the buffer in case of overlap (i.g. [block~ 512 4]) if stopping/restarting the DSP.

x->x_fill = prologphase ? x->x_endbuf - (x->x_hop - prologphase * re_parentvecsize) : x->x_endbuf;

The change above might solve the problem.

I'm not 100 % sure. I'm currently testing the fix on Spaghettis < https://github.com/Spaghettis/Spaghettis/compare/dev >.
