Playing back a song, Sonar stops just where the 18 tracks of background vocals start. only 2 of the BGV tracks aren't muted, and I plan to delete most of them. But I plan to replace them with a different arrangement that works better. And I think some people work with vastly higher track counts without problems.
 
Those tracks all start in the exact same place; there isn't (or shouldn't be) any reason to go back to the beginning of the song to record BGVs that don't begin until towards the end of the song.
 
What do you suppose is causing this problem and what is the solution?
 
This is at 24 bits, 96kHz
system details are in my sig

Its either 1 of these 1 things:
1.) Your sound card buffers/sound card settings are to low for that specific project. Just raise your ASIO buffers and maybe try raising your payback buffers also

I'm with CJ, 18 tracks coming in at once could tip things over the edge from enough sample buffers to not enough sample buffers.

Try archiving instead of muting the unneeded tracks.

Muted tracks are still processed.
Archived tracks are not processed... so archiving those unused tracks should help the OP.
 
That said, 18 tracks really isn't that many.
Are you using the USB option for the Lynx?
What's the current ASIO buffer size?

AES16e, not USB
The current buffer size is 2.7 msec or 256 samples.
The slider is all the way to the left, "fast".
The slider is greyed out and won't move. I opened the ASIO panel and changed the sample rate to 1024 but the slider is still all the way in the "fast" position. It shows 2 playback buffers and won't let me change that number.
The song still stops.
I know muted tracks are processed there are probably going to be at least that many tracks unmuted for the mix and I am sending them to a BGV stereo mix bus.

So... you guys are stumped?
 
Sorry if I come here with tricky problems, but the easy stuff I can solve on my own.

If raising the latency is not helping, try raising the playback I/O buffer size (in preferences sync and caching | file system).
If its dropping out with 18 simultaneous tracks its likely that your disk is not performing optimally - try defragging it and run a disk test since it could be going bad. Another thing you can experiment with is enabling read caching in the same page.
Also copy the project and its data to another drive and try playing it from there.

As I mentioned before, I can't do either. AFAIK I can only access the number of buffers in playback queue and buffer size from preferences/ audio/ driver settings, and the slider is stuck on fast and greyed out, the # of buffers set to 2 and not changeable.
 
Anyone know  why that is?

Thanks, Noel, I'll try that.

How do you do that?

I routinely store projects on two separate external hard drives hooked up via usb3. The same problem happens with both of them.
 
Oddly, although the current tracks are all audio tracks, I can change the MIDI number of buffers and buffer size by going to preferences/ MIDI / Playback and Recording. Too bad this song is only getting maybe 2 MIDI tracks and the rest are audio instead of the other way around.

The mixing latency slider is disabled when running in ASIO recording mode. Software supplied by the interface vendor must be used to set latency when running in ASIO recording mode.
