why do i have latency only when recording on my vst? thanks!

So...

I think you notice the latency only when recording. When you play back or mix down, you don't notice the latency because you aren't trying to play in sync.

When you play along with pre-recorded tracks and have a vst that adds latency (like perfect space), the latency matters to you.

Is this what you mean? If not, please say a little more so that we can get a better grasp of where you're going.

when project its playing the synts sounds with big latency. when project its stoped it doesnt have latency

So, are you saying you are input monitoring your synth but when you hit record the latency gets worse. When you stop the transport the latency goes away? Hmmm. I'll have to think about this one. I know if you bypass FX using the global FX bypass button this can make latency disappear and reduce the processor heat so your PC can run cooler.

So here's a shot in the dark. Let's say you have one track running through perfect space with a pre-recorded track on it. When stopped, nothing is being sent to the Perfect space VST. You have a separate track routed directly out, bypassing perfect space). When you only play through that channel, there is no latency. When you hit record or play, the other track is suddenly routing through the VST causing the latency.

Just a guess

What VST is it you are trying to run?

You can try hitting the [PDC] button on the Control Bar as well as the [F/X] gswitz mentioned

Heres something from the manual

There are several ways to play a soft synth:
• You can record MIDI data and use the soft synth as a playback device.
• You can play the soft synth in real time from a MIDI controller or keyboard. To avoid excessive
latency, your sound card must be using a WDM or ASIO driver. Also, you must set mixing latency
to the lowest achievable level (probably less than 10 msec.), which you do by adjusting the Buffer
Size slider in Edit > Preferences > Audio - Driver Settings.



Also , what are your Playback I/O and Record I/O buffers set at?



ADDED

Bypassing effects globally
SONAR allows you to globally bypass all audio effects in a project. You can also choose to only
bypass effects of a specific category (track, bus or clip).
With global effects bypass, you can:
• Quickly compare (A/B) a dry versus a wet mix.
• Temporarily bypass all inline plug-in delay compensation (PDC) effects in order to avoid delay
compensation induced latency while tracking virtual instruments or input monitored tracks.
• Temporarily reduce CPU consumption.
SONAR also has the ability to bypass effects at a per-effect level (effects bypass) as well as at an
effects bin level (bin bypass). Any existing effects and bin bypass states are preserved when you
globally bypass and unbypass effects.

thanks, PDC did work

 Wonderful
