Hi, I don't use Vst instruments, so I don't need low latency, but if you use them, 7ms is decent enough...and not too demanding. If it's all tight with it you can try lower.

Well that depends on the sequencer you use, delay and buffer sizing. Setting may need to be changed when tracking vrs. mixing. For me personally when tracking I like to set as low a buffer as possible, but not so low the your system will explode and be brought to its knee's, so lets say a decent tracking buffer of 128, which should roughly equate to around 4ms of latency, then a mixing buffer of 512 which translates to around 6.x-7.x ms latency.

It really depends but those two settings are pretty general, of course there are many things that can change this, one being track size and audio count etc.

Changing these settings wont hurt a thing, you can always change it back, but I can say one thing for sure, if you have a half decent sized track count, I wouldnt bother with trying anything under 128 buffers, this will undoubtedly cripple your PC :wink:

YMMV..

I use 13 ms ,with the quantising its ok for me.Obviously you can go 7 ms but can you record ,for example ,16 audio without any clicks or stuff? With 13 ms i can do this ,so i dont have to swich from 7ms(play) to 13ms(rec).

i don't also use any vst instrument. just reason and sonar and i'm ended up at 13ms. 7 or 10ms cause me nothing but crackles...can you tell me how do you do that 7ms!!!

i can easily get to 4ms, usually run at 4 or 7ms (all at 44.1) and occasionally when i've got lots of tracks of audio go to 13ms for final mixing.

That's running on a Mac G4 500Mhz SP.

This is my performance report:

3ms (1.5ms in sequencer): high CPU utilization, prone to clicks and pops, poor reliability

4ms (2.9ms): slightly better reliability, but still high CPU utilization

7ms (5.8ms): still rock solid timing for soft synths, but much better CPU scores and reliability -- use this for tight performances

13ms (11.6ms): good general pupose setting -- 90% reliability (occasional click or pop when under heavy stress) and decent for performing

25ms (23.2ms): 100% reliability, no sound flaws whatsoever, excellent for mixing, but unacceptable for performing

I usually use 13ms unless I want solid timing when I'm performing, and then I switch to 7ms. Occasionally if I have a lot of Pulsar and DXi synths running at the same, I have to go up to 25ms. But I think 13ms is good for most stuff.

Where i can see this 1.5ms? do you use Sonar?

Yeah, I use Sonar. You can see it in the audio options. I actually think Sonar reports the latency going from Windows to Pulsar, and in CW's ULLI box they tack on another 2ms going "through" the card. Just my guess....
