I also am trying to find this awesome dialogue box I had for setting the buffer/sample rate. I can't remember where I got it Ableton ? Focusrite ? ASIO4all ?

Asio4all used to be a good one, but most modern sound cards have their own asio drivers. Probably your scarlett has a control panel for buffer size in some sub menu. MME is fine, but on my system it causes a delay of about one second before playback responds. As Noel suggested: try bypassing your virus scanner for the whole BIAB folder, that sometimes solve stutters and delays. But on my system BIAB 2018 definitely renders slower with the same (a complex arrangement) file as 2017. I mailed Kent - PGsupport about that, and i guess he's looking into it. He tested the same file, and has found no problems, but i still do. Biab 2018 takes 15 seconds to render all the audio, while 2017 does the same in 5 seconds, a puzzle .... A melody track usually comes with sounds generated by a softsynth like Coyote, try another one maybe? -F
