Hm, I am surprised you get much to work here, you have jack configured to have a 512 period buffer size and bristol is going with 1024. Try "startBristol -b3 -count 512", that should get you much better results. I have discussed how to determine this correctly from the script, and at the moment I parse ~/.jackdrc, the process table and finally resort to the jack provided default of 1024. I admit that should not cause seg fault.
 
The last proposal I was given to resolve this issue was to start jack from the script and request the buffer sizes in advance (I need these for some internal initialisation sequences - long story, the MIDI library must be started before the audio is started since it is a midi command that starts the emulation. To start MIDI I need to initialise code sections that use the audio parameters such as sample rate and buffer size, to build the frequency tables amongst other things). Hence the bristol engine needs to know this apriori. The option to have a program start the jackd to request its audio parameters, then have it die, then start it again for bristol from the libraries seems daft - I am happy to take some of this on advice.

This appears to be the same issue - at least from the diags.

I will look at this as it should be centered and it should have been a memory parameter since different layers may be panned differently.
