Setting up buffer size with Presonus AudioBox

[johnm]

I am having the same problem using a Presonus R24 mixer as the audio interface.  I set the buffer block size to 256 but as soon as I start a session, Jamkazam changes it to 16.  It works but there are a lot of annoying artifacts in the sound.  I keep trying to change it but it only changes back.

Yep, that is basically what I see.  I can not find anywhere in the actual JK application to set the buffer size, and somewhere it seems to have 16 set, and that overrides what you set in the Presonus interface, afd as you say the sound is not good.  Really anoying!
