Hi,
I have produced a few tracks in Sonar and want to be able to play them live.
So I rendered all my tracks to audio (44.1, 16bits), chopped them into audio clips and set them up in the Matrix.
All good so far, except each time I load a project, each cell will have a latency when played the first time, as if they needed to be played once before being set in memory.
If I play them all once, and THEN play live, it will work fine. But if I reload the project (when I switch track to play live for instance) I would need to do that again. Which is obviously unacceptable...
I have setup my driver at 48 samples and have a latency of 8.8ms, and the MIDI buffer is at 500. I tried several settings with no luck...
Any idea?
Cheers,
Laurent


EDIT: My CPU is at very low usage, so definitely not a problem of computer performances

Your machine has about the same as mine - same chip and all, I just have more memory (32 GB), so that is not the issue for you.

Could it have anything to do with Sonar's Mixing Latency buffers?

Here is the link to that from the doc:

http://www.cakewalk.com/D...dioPerformance.16.html

Just a shot - I will see if I can dig up anything else.

A thought, I used to create exercise class mix CD's for the now ex, and her requirements were to have no gaps at either end, so I would edit a bunch of imported tracks individually to get rid of the gaps (slow intros - long stupid stuff at the end), and I would also arrange them in terms of tempos per her class needs.

So, I would finish one track, then position the Now Time marker and import the next one onto a new track, then edit that one and slide it over if the beginning needed to get snipped.  And so on, 

Would something like that work with what you are trying to do?  When I do these, there is an option to eliminate gaps when I cut the CD's, and it works out for her.

Check out the following doc link:

There is a default setting that is not inherently set for what you are trying to do, I think.

The parameter is Trigger Resolution, and the default setting is to force a WAIT until the next measure before playing any given cell.

I think the option you would want it Immediate, which is available - see the doc.

Hope that helps, 

Bob Bone

Thanks for your reply.

I don't think it's linked to the Mixing latency as I don't experience dropouts.
I have tried a few settings without luck.

I understand the Trigger resolution but I don't want my cell to launch directly, I want it on the beat as it is configured by default (similar behaviour than Ableton Live)

And please be aware that after playing all columns once, the whole thing works perfectly! As if Sonar had to "load the sounds in memory"..
Sounds like a bad memory management to me, but maybe I am missing something.
I am supposed to play on Saturday and I'm in deeeeeep trouble if I can't solve that...

Thanks anyway

I would imagine you are correct. The samples have to load into memory. Maybe SONAR is the wrong tool for the job.

from running matrix in x1 in live settings with both midi clips and audio clips, i've learned the following...
1) hit play in a project with some audio clips as an intro - maybe 2 bars or so
2) set dropoutmsec in config file to 750
3) set extrapluginbufs in config file to 32
4) make sure in driver settings that your playback timing master is set to the audio out of your primary sound card.
5) trigger cell columns with a midi cc or note from a controller like the korg nano pad because doing it from a keyboard device can inadvertlently trigger synths if you have midi channels and echo midi options not set correctly for live performance.

Hi,

Thanks for your advice.
I didn't know this config file and learnt a lot from your post.

Now I can't say I'm happy with the performances I witnessed. I tried your exact settings, + a few tweaks of mine and couldn't get am "instant" feel.
Basically I had to stop the music for 30 seconds (!) before playing the next track because I have to click play on every cell before I can play my track live.... as I said before:  unacceptable.

I will log a case with Cakewalk to see what they have to say about this.

Anyone else experiencing the same problem?
Cheers,

you can trigger columns in addition to individual cells - that what youre looking for?

No no not at all.
Let's be clear I understand how the Matrix works... it just doesn't work well, at least with the default settings.

Quote from my post:
"please be aware that after playing all columns once, the whole thing works perfectly! As if Sonar had to "load the sounds in memory"..

I HAVE to play every columns once if I want the clips to launch properly when I click. The 1st time I click on a column after opening a project, it will have a 0.5s dropout before playing the column.

Applying the settings proposed before helped a bit, but it still sounds clunky, and I looked stupid during my Live on Saturday... ><

ah my bad didnt reread whole thread. yeah x2 matrix is a bit more blech than x1MAYBE the x2a patch will help... 
and dont worry about looking stupid. even platinum artists have had those moments - amy winehouse comes to mind.
kinda at a loss for what to tell ya. experiencing my own matrix issues in x2.
