Instrument track plugin performance issue?
 

Hi there,
first post, first problems, hope somebody can help or give a hint.
I'm wondering if my hardware is to slow or if there is a bug in Pro Tools...

That's the way I can reproduce the issue:
- I create an instrument track, assign a plugin (e.g. Kontakt 4 - which is loaded in a few seconds) and record midi
- When I create a second instrument track and try to assign a plugin (e.g. another Kontakt 4 or Xpand2) it takes about 4 minutes till it's loaded (with an apple spinning wheel)

Funny thing:
- If I just create instrument tracks and assign plugins without recording, I don't have any performance issues...

Can anyone tell me what's going on here?

Thanks in advance
Joerg

I would venture to say u got some other programs running in the background...other then pt thats eating away at your processor...i dont beleive kontaki4 is memory hog but make sure u dont got anything other then pt running.

No, only Pro Tools is running. So you think it's not a general performance issue? More like a configuration / compatibility problem or something like that?

Both those plugs are hogs, especially K4 so the question is why would u open 2 of those when u should jus create Midi tracks.. Either way its still a matter of what instruments within K4 u open as to what |how the performance would be affected...

The problem occurs also if I use another instrument plugin.
E.g.: I create an instrument track with Kontakt 4s Abbey Road 60ies Drums and record midi.
When I create a second instrument track and choose Xpand2 as plugin to record a midi bass track it takes 4 minutes (with a spinning wheel) until I can use Pro Tools again.

Crazy? Hardware too poor? Configuration wrong?

Make sure all plugin versions are compatible here

Make sure your RTAS processor count = max - 1
