Problem: CPU level go hungry when Groove Agent One is ON

[Tomateck]

This is the issue:

- Create empty project
- Add Groove Agent One in a slot VST instruments
- From MediaBay drag and drop some drum samples on GA pads (I've 1kick, 2snares and hiHats)
- Record 8 bars of a midi drum track and duplicate it 8 times
- add other instrumens and record other parts (bass, piano...)

-> Result = After 15min. of working, the CPU usage is on med values, after 30min is hungryyy!!

- go on th ASIO preference panel and set another value:

-> the CPU usage return ok, but after some minutes return on hightes values.

- turning off Groove Agent One this problem desappear!

I'm on P4 3Ghz - 2Gb RAM
RME Fireface 800
Motif XS (USB connection)

Please help me! Is it a BUG?
