Cpu Overload .....already???, Protools / Powerbook G4 Options

[vinrock]

Hey guys, I'm hoping this is a simple oversight on my part and one of you can help.

I'm getting constant 'CPU Overload' errors when trying to record an audio track. This is what I have for track listings, plug ins etc... I'm on a brand new Powerbook G4 1.67 1.5 gig ram

Tr 1 - midi drum track
Tr 2 - Aux track - BFD drum plug in ( I suspect this is very CPU heavy)
Tr 3 - Audio track I'm recording guitar on (clean)
Tr 4 Aux track - Amplitube
Tr 5 Aux track - click (for count in)


Settings are:

CPU Usage limit - 85%
DAE PLayback Buffer = level 2 (default)
HW Buffer Size - 512 it tracks a little longer on 1024 but the latency is a killer there

My completely newbie guess is to pull out BFD and just use a midi drum sound while tracking, then crank H/W buffer for mixdown but could it be something else. Is that the max this Powerbook can handle?

Thanks so much in advance and hope you all have a happy and safe New Year !

right vin, the BFD drum plug in is very CPU intensive,
i had the same problem with my G4 MDD Dual 1.25/2GB ram - MBox2/PT LE 7.0 - Tiger 10.4.2,
when using the Bosendorfer and a few other plugs; simply put my G4 could'nt do the job;
i bought a new G5 Dual Core 2.3/2GB ram and now i can work with a lot less problems (PT LE 7.0 is still buggy, but i suspect not all the plugs and synths have been upgraded for it to work).
i'm also upgrading the 2gb ram to 4gb, it seems that, these times, the more ram you have, the better you work. byez.
