Long time lurker, first time poster.
First, thank you for mulab, it really is a beautiful piece of work.
I've only recently begun to move away from working with plugins alone and into utilizing both VSTi and "real" instruments - bass and guitar - in mutools.
I lay down a basic MIDI drum track using BAttery or whatever. I then lay down electric bass and/or guitar audio tracks. My problem is that on playback or monitoring for tracking the VST track lags behind the audio tracks. This makes no sense to me but then the whole latency thing has always confused me.
Note that it matters not what VSTi I use for drums, they all give the same results as far as lagging behind the audio tracks. I have a fairly fast 2.66 gHz PC and a now ancient Gina 16 bit sound card.
To sum up - Help!
VSTi tracks lagging behind Audio Tracks

Nope, that's got me floored.
Let's say you had 1 second latency on input and output. (Just to make things clear!)
If you laid the drums down using MIDI "live", you'd having to wait 1 second between triggering a drum and hearing it. If you just painted the notes in, you still have to wait 1 second between the note triggering the VSTi and the sound output.
Now, on the audio side...
Whether you're recording to click or the drums, there will be 1 second before the sound gets from MU.LAB to your speakers. Then another second on the way back in as you play. So that should actually be two second behind the drums...
But you're saying the MIDI drums are behind the audio.
It certainly doesn't sound like a latency issue.
What if you get a single shot audio sample (e.g. of a snare hit) and do this:
Track 1 - load the sample as an audio sequence
Track 2 - load the sample into a Sampla and trigger it from a MIDI sequence
Do the two play together?
A screen shot or sample MuSession might help...
And does tracking to the built in click make any difference?
To sum up - how very odd!

I did the above, no flamming, sounds tight but I didn't go too far with the experiment.pljones wrote:

Is there any chance that, on my system at least, the MIDI clock could be flabby? If my MIDI clock is dragging or modulating in time then the MIDI drums could drift behind the audio. Right?
I will say Mulab doesn't sound or feel as tight as my Cubase SX which in turn doesn't sound or feel as tight as my old Amiga, but that's a whole other story. Maybe I need to do some system tweaking.

Using the same Sampla, stretch the MIDI part out to use as click for 16 bars and record some audio against that.
Where on the timeline does MU.LAB place the audio?

It could be that your soundcard is not properly reporting its latencies to the software.
In that case any audio you record will be placed out of sync with the midi data.
Please read this page in the docs about audio recording:
http://www.mutools.com/mulab/docs/recording.html
Below in the "Recording Audio" section you'll find more detailed info on how to finetune the recording latency if your soundcard would not report it properly.
Hope this helps.
