Live cpu?

[Jesse Gorter]

Hello,

as a user of ableton live 4, I have some weird experiences. I recently ditched my sblive! digital for a terratec phase 22. I have 512 RAM memory, 2.8 ghz pentium 4, 4 gig free space but my comp seems way slower now than with the sblive!

The thing is:
I load 1 audiosample of 16-bit in an audiochannel

and 1 bassline in a midichannel running through the korg ms20 and a classic chorus.

When i play both channels now he has a lot of trouble eating about 30-60 % of cpu! only two channels! That didn't occur before....I just cleaned my registry, defragmentated my hd, but it's still the same.

Other statistics:
Input latency is about 60, output about 20. buffersize is 1024 samples...

Does anyone understand this? Because I'd like to know:
1. is this normal with my hardware?
2. isn't the terratec supposed to increase my ability to load more vsti's?
3. What can be the cause?
4. is there anything that I can do about it?

Thank you,
Jesse.

Try decreasing buffer size. What drivers are you using (ASIO, directsound, etc.)? I am running 16bit, 44.1 KHz ASIO on a US428 with 256 buffer. I have a current song I'm working on with 3 audio tracks, and 4 midi channels running LLP2, Rez(x2), and Texture and I get a spike of about 34% cpu usage. I have a 2000+ Athlon and 1 gig ram. The 34% is mostly from running the softsynths. Overall latency is 27 ms (20 output, 7 input). If I run at 24 bit, 48KHz I get 6 ms input latency and 26 overall. This is on a PC optimized for games, office, doodling, music, and graphic design. OK, so it's not really optimized for anything specifically.

Uhm, I will have to check it out.

So basicly the idea is: keep your samplerate and audio settings the lowest in live, but keep your export audio settings the highest so you still keep full quality?


Does seem to make sense.
