Garritan Personal Orchestra with Sonar 4

[terryko]

Any people use GPO here?

The quality of GPO is quite good for me,
but annoying, because of the latency.

Here is my situation,
I use GPO for output in one of the midi track Sonar 4 Producer Edition.
Then I play my keyboard,
sound comes out from speaker with selected voice from GPO,
but in about 0.5 sec delay.
However, playback is ok without any delay.

I am annoying because I cannot listen to the GPO sound while recording for MIDI track.

Please help~~~~~~~~:mad:

Yeah, GPO is pretty demanding...but man it's nice. You can try lowering your VSTi buffer size, increasing your amount of RAM, or freezing other tracks while recording.

Thanks,
however,
I discover that it's not only the problem on GPO,
when I use TTS embedded in Cakewalk,
same problems.

Is that the problem on using software samples?
I use 2.5GB for RAM,
how can I lower VSTi buffer size?
freezing other tracks, means muting other tracks?

thanks for advance:)

freeze is a function on cubase sx3... its processing in place, so that u can free up CPU.... not sure if cakewalk has it...

You have plenty of RAM. I only have 1gb and that works fine for me. Well, for the most part anyway. I'd definitely like more...but back to your thing...

I'm not sure how you do it in Sonar, but you can usually set the buffer from within the settings/preferences of your software. You may also have to change it in either your audio interface's or you sound card's control panel, whichever the case may be.

While you're in there, check what your input latency is (if you can find it). It should be about 3ms - 10ms. Anything more than that isn't very good and could be part of your problem.

Sample based plug-ins give awesome quality, but eat up tons of resources. That's why I suggested freezing the other tracks. That's not like muting at all. What it does is temporarily bounce everything in the track you're freezing to disk, including automation & effects, until you unfreeze it. Then your audio software will do the playback using the bounced information instead of doing all the work in real time. If you have a lot of tracks, that alone can free up huge amounts of resources. Most high end audio software has that functionality. Check the manual that came with Cakewalk Sonar for details, or do an online search. I'm almost certain that Sonar can do it.

Also, check to see if your ASIO driver is set up properly. You want to use whichever one gives you the lowest latency.

I also use GPO and Sonar, so try this:

1. Open Sonar

2. Go to Options->Audio

3. You should see 'Mixing Latency' and a movable buffer size bar at the bottom. Move it left to fix your problem.

The lower the buffer sizer, the better you'll be able to play in and realtime and without latency issues. Your computer should be able to hold it. Be sure to crank the buffer size back up when your mixing. You should often be moving it, depending on what you're doing.
