Cakewalk buffer size

[Jono J Grant]

Hi, I recently installed a version of Pro Tools to open some projects etc. to move over to Cakewalk.

Curious, why does Cakewalk require much higher buffer settings than Pro Tools?

I use UAD Apollos and normally with a bunch effects inserted into Cakewalk, I need to select a high buffer like 2048 to get smooth playback.

Pro Tools won't even let me push play unless I change it to 256 or lower, and this is w/o any plugins.

Is it that Cakewalk relies on some Windows audio system whereas PT uses it's own?

 

Thanks

Jono
