How many plugins - Cubase sx VS PTMP 7.1 cpu power

[sonuslab]

Hi guys, I'm a PTMP 7 newbie, now changing from cubase sx to protools. My daw is an intel based P-IV 3GHZ/1GB with 3 delta 1010.
I've got a standard studio session made by PT HD on a mac (that I can read very well in my pc station!) with 20 mono tracks at 44/24 and some plugins, like the new native digidesign EQs or compressors, one dveb, one IR1 and one tap delay but the CPU power needed to run the project isn't enought.
Same session in cubase can load plenty of plugins, three impulses reverbs, many vst instruments and no load problems, here in protools only few plugins and the cpu is gone.
Has anyone noticed my same problem?
There is anyone with a similar daw that could insert more plugins than 5?
Thanks a lot,
Marco

If you are using DVerb, you are probably experiencing "denormalization". Insert a dither or other low level noise making plugin before the DVerb.

Any other answer is going to require that you post the complete specs of your system. PT and Cubase are two totally different animals when it comes to hardware requirements.

Thanks a lot for your reply, I read all posts in this forum and unfortunatly I already tried the denormalization process and it is the same, with or without dverb in insert. When i'll go to playback the session, pops up the "...more cpu power needed" alerter, even if the PT cpu indicator is at 30% more or less.

My DAW is a simply intel P-IV 3GHZ with 1G ram and a intel 865perl mainboard, without ethernet, nor strange periferials, only 3 delta 1010 with the latest drivers, two HD, one for audio and one for software, winXP SP1, tuned as described, nor surplus services running... I don't know...

The session is:

1.kick condenser + 7band EQ3
2.kick dynamic + 7band EQ3
3.snare1 top
4.snare bottom
5.snare2 + 7band EQ3
6.HH
7.Tom1
8.FloorTom1
9.FloorTom2
10.OH ride
11.OH HH

12.DBass Line + EQ3
13.DBass Mic + EQ3

14-15 Piano

16.sax1 + EQ3
17.sax2
18.Tbone + EQ3

19.vocal

20-21-22 little fx tracks

aux 1 Master Drums + Rvox
aux 2 Master Dbass + EQ3
aux 3 Master horns + RVox

end of cpu power.

these are not loaded:
aux 4 IR1
aux 5 IR1
aux 6 DVERB

10 plugins and the cpu is out of power.
Is this right with this kind of session? just to know if this session is too hard to run, or if my daw has some problems.

Thanks a lot, Marco from Italy

1. XP SP1 is not supported but it has worked for some.
2. mutltiple sound cards are not supported but it has worked for some.
3. Try increasing your buffer size
Setup menu -> Playback Engine -> H/W Buffer size

ok go to sp2

2. mutltiple sound cards are not supported but it has worked for some.

working!

i'll try.
Thank you!
