WinXP + Pulsar 2 + Sonar problem

Funktastico · Post by **Funktastico** » Tue Nov 06, 2001 1:28 am

Greetz,

I'm using Pulsar II 3.01, Sonar 1.02, Win XP, Duron 800, Abit KT7,...

Everything works perfectly, low latency on the WDM drivers and all (20ms), BUT, Sonar seems to fuck up latency correction.

The higher I set audio latency, the more negative delay all the audio tracks must have ofcourse, relatively to midi tracks, but Sonar seems to add too much negative delay to audio so that I must add negative delay to midi tracks to fix it, and that is a pain.

So... anyone else having this problem? Any ideas?

Oh yeah one more detail, 48khz/16bits.

Could the DMA buffer sizes in Sonar be set wrong by the wave profiler or something?

Well, haven't you found a solution yet?
I'll be using the same config so it'd be nice to know how to fix the problem, you know...

Thanks in advance.

Yes, found it after swearing my guts out a few times.

Sonar triples the negative delay needed to get your audio and midi in sync. Don't know if this is a problem with Pulsar WDM drivers or Sonar or whatnot...anyway there's a simple work-around:

Set a delay in your pulsar project to all wave sources, with a delay time 2x your sonar Latency setting.

Eg. your Sonar latency=50ms, delay wave sources by 100ms to get your midi and audio back in sync.

If you don't want to spend DSP for the delay you can also force Sonar to use MME instead but at least for me, the timing with WDM is a lot more accurate and I can get lots more power out of my lame Duron.

Excuse me mate,what i must do for delay the waves sources?
Let me know...see ya!

Add a delay effect to your project, wire the outs from Wave source to the INs on the delay, and the outs on the delay to the mixer.

Set the delay time to 2x your sonar latency, dry=0 and wet=maximum, feedback 0.

Humm...
Seems a bit... erm... cumbersome, I'd say. Thanks anyway. Though I hope there's some another solution. I'll use yours as temporary while searching for the perfect one. Heheh...

Yeah... same here.
Let me know if you find something

Hey Funk, I recal Sonar uses the wave devices for IO... how many can you load? I'm trying to get Samplitude to work in XP but can see only 8 wave devices.. and the windows driver only lets me load 8. I was just wonder how the other wave device users were dealing with this.

Yeah, same thing with Sonar.

v3.0 didn't support more than 2 wave drivers as I recall, still it would let you load more (8) of them but there was no sound coming to and from them I think. Do those 8 drivers all work in 3.01? If so, that's improvement.
