Native Instruments in PT 12.1 cpu overload?

[tonykitowicz]

Hi,
I have a mid 2012 iMac with core i5 processor, 8GB of ram.

I have 12.1 vanilla and create a blank project with 1 instrument track, 1 stereo audio, and stereo master track. I inserted Machine 2 into the instrument track and have a simple 4 bar beat. Playing guitar through the other audio stereo track.

After less than 2 minutes PT 12.1 makes a loud distorted sound and freezes with a dialog that there wasn't enough CPU for processing the audio. At that point PT 12.1 is completely frozen and needs to be forced quit.

I also have Logic Pro on the same system and can go for at least an hour and half with the same scenario without any problems.

The audio interface is the same in both scenarios, RME UFX and there is nothing else on this computer. I didn't have Protools on this iMac before today and was going to wait until the end of the year, but when I saw the 12.1 update I decided to try it. To be honest right now, I really wish I hadn't upgraded.

I'm guessing that most people don't use Native Instrument products in Protools.
