KVR Audio

So I just had this jam session last night where Ableton Live 5 would have severe audio dropouts when i tried to have four instruments/ mics recording simultaniously. First the hardware breakdown:
Digi 002
Athlon 64 3500+
Abit MGuru motherboard
2 Gigs Corsair Ram

I Had the sample rate at 48.0. And both Ableton and Reason are set to take advantage of 80% of the CPU. I was getting big latency just with a mic'd drum, two guitars and Reason 3.0 with two Combinators. So I had to compensate by adjusting the new delay setting at the bottom of each channel in Live 5. Then when I tried plugging in the last mic the audio completely dropped out for all channels. I had to disable the new mic channel in order to get any audio. After that the recording went without a hitch, sans the last mic with sucked because I missed out on some cool recorded vocals. During the whole session the Windows CPU meter hovered around 86%.
My question is: am I asking two much from my current home studio setup or am I NOT doing something in Ableton Live that would allow for better allocation of computer resourses? Thanks to everyone in advance for your thoughts.

I would have thought that what you have there would easily cope with the task.

Only this weekend I recorded on four tracks [albeit on two stereo ones] on my P4 3GHz without problem. CPU wasn't doing anything over 30% or so. Reason was stacked up with a load of NN-Xt and a few combinators too.

What I would do though is turn off PDC. It doesn't seem to work on my PC with rewire. OK latency will go up slightly on any VSTi but rewire will run better.

Also turn off auto-warp. Warping uses a lot of resources and I only warp a particular sample if I need too alter it in some way.

what bit depth are you using?

Is this a dual processor box? If so, try shutting off one of them.

Thanks for the replys. I don't know what PDC is. You'll have to enlighten me.

Also I'm not familiar with auto warp. Is that an option in the preferences?. I'm using 24 bit depth. And I'm only using a single processor box. Any other thoughts?

PDC is plug-in delay compensation. Its in the Options menu. Deselect it if it is ticked/checked. You can put it back on later if you need to do a lot with VSTi and other non native plug-ins.

Warp mode:

Option - preferences - default.

Turn auto warp long samples to off.

Also, Hi-quality off.

Make sure warp mode is not set to complex.

This may not help, but its worth a try.

Live 5 recording limitations?
