System grinds to a halt...

minipax · Post by **minipax** » Tue Jun 11, 2002 2:40 am

when i switch my pulsar to 96khz mode my PC just grinds to a halt, i have cubase open at the same time at a different sample rate (i cannot change the sample rate in cubase casue i get a 'external audio clock?' message)

my PC is an Athlon 650, 384 MB Ram,

is this a slow computer problem or some kind of samlperate sync problem?

cheers!

96khz requires more than twice as much DSP power as 44.1khz. Therefore, if you are anywhere near half your DSP load when you switch, all of the sudden your project will be larger than the amount of DSPs, giving problems.

Also, I would highly recommend that you set the sample rate *BEFORE* opening your sequencer, and definitely not with it open at the same time. You may have to manually change the samplerate in Cubase to match, not sure...

Yoy should also UPGRADE that 650 processor to at least an Athlon 1. something for better performance. They are more economical so get the fastest one you can afford.

old response:
do you REALLY need 96k? are you making cds?(44.1k)

96khz is cool but just make sure that you load the project first.... before cubase... cubase might have issues with that... Depending upon what your aplication is for the 96khz you might not need it... I use it so that I can represent (at the highest possible quality) my harware modular synthesizer. Quality is a big issue for me... and when I dither this down to 44.1khz it has a clearer representation of what my synth put out. You should figure out if you really need it. when you get this up and running try recording at 96, then 48, and then 44.1 and see what you find to be the best...

Ok... datz enuf,

thanks for the answer guys, that helped!

as for needing 24/96 recording, well i don't need it for quality but for the latency of 1ms!

i have just starting getting into recording audio into cubase and the latency is a pain in the arse, i can't get my audio in sync with my MIDI parts without first spending a half hour moving the audio around till it sounds right, very counter-productive!
i know i'm probably doing it all arsed-ways so can any one give me some tips for coping with latency?

and as for updrading my CPU, would i be able to install an
AMD Athlon XP Socket A 1800Mhz CPU without havng to change my Motherboard?
dunno the motherboard make at the moment but it's got a 650 athlon in it.

thanks!

use pulsar mode when recording audio and latency will not be an issue.

what do you mean? use pulsar mode when recording audio??
what's 'pulsar mode'?

I don't use XTC if that's what you mean...

Then why do you need 1ms latency ?
I mean, there's (virtually) no delay when monitoring audio through asio2 drivers...

yeah, my old pulsar1 cards only do 13ms and i have NEVER had a problem doing overdubs or punch ins.latency is not a real issue.it's only an issue if one is living on specs.

not monitoring, recording. if i record say a 4-4 kick from the esi8 into cubase it'll be fractionally off. look, it doesn't matter, i realise i just have to live with it and edit all the audio i record.

cubase it'll be fractionally off

Something's wrong then. At least with Logic, it automatically compensates for this, I would expect the same is true with Cubase?

AHH-HAA...
Creamware devices are like a hardware midi synthesizer in that respect, not like a VSTi:
There's latency even on playback...
Nothing you can do about it, unless someone replaces the standard midi system with something else

Yes MIDI isnt sample-accurate like a VSTi. But if you get an AMT (for Logic) or a Midex (for Cubase), MIDI does get more accurate. I use an AMT8 w/ Logic and it's pretty tight...

ahh, midi timing is another(midi) issue...
