I have another weird one, owners of trigger finger pro.....

[incubus]

I was surprised after much testing that I came across this. Again, win10/x64.

Load a spacial plug (let's just say NI replika or whatever, maybe the built in reverb) on an audio track, no other FX. Input to the soundcard input, so that you have whatever signal.

Now, with the TFP OFF, try switching either rex or wav in the preview from whatever to whatever (doesn't matter which loop, etc) and whammo. CPU overload from hell.

The workaround (duh) is to make sure TFP is ON. Then that's not an issue. Might be my settings for controller, but just in case someone else has the problem wanted to point it out.

One other thing, the loop preview isn't super "tight" all the time in the preview. Sometimes the last bit seems like it's cut off (though the loop is indeed in time)
