Re: ardour export + jamin

Hi Jack,

Thanks for the quick reply and instructions. I'll try to do that later 
tonight.

My .jackrc contains: /usr/bin/jackd -R -dalsa -dhw:0 -r44100 -p64 -n4. 
So indeed 64. I minimized that to get a minimum latency without xruns 
(but without thinking about it).

I did some stderr logs of the cnt that the ring buffer write did and the 
nbytes, and most of the time it was 1 byte short, so cnt=255 and nbytes=256.

Thanks,
Kees
