Hello All,
 
First, here's the current rig:
* AMD Ryzen 1700X, 16 GB RAM, SSD, Scarlett 2i4
* Windows 10 (Version 1703)
* Cakewalk Sonar Platinum (Version 23.7.0 Build 37)
* Using ASIO drivers (96000 Hz SR @ 24 bit depth)
 
Hoping that someone has either heard of this, experienced this or knows what might be causing this... The issue I'm having is independent of a specific project, track or FX/plugin. What's happening is that any time a track is hard panned (literally 100%) I get bleed over into what should be the silent channel. I reproduce this regardless of whether I use the track pan control, channel tools, or even mute a channel on the hardware output in the mix console. What makes it REALLY weird is that if I back the pan control to 96% I ALMOST get a perfect hard pan. Now, my gut instinct was that this was a hardware issue so I swapped to an older first gen 18i8 that I had; no change. I've gone through multiple iterations of isolating and identifying, and the nail in that coffin in my mind was that if I export a single track panned to 100% either direction, the exported WAV exhibits the same issue. If I export a track panned to 96% either direction, I again get an almost (but not quite) perfect hard pan. Recognizing that the audio interface was still a common factor I plugged a set of headphones into the motherboard sound card output and replayed the exported files; same exact issue. To further isolate I copied the audio files to my phone and played back from there... Same result.
 
I'm at a loss at this point. My gut is that this is likely a Sonar issue (particularly since ASIO exhibits this issue) but clearly Windows is always a layer that must be consider since it cannot be removed from the equation. While I do however feel like Windows is unlikely to be the culprit, who knows...
 
Anyone seen this? Have any ideas on what to try?
 
Note: I have verified that I wasn't doing something dumb like having offset mode engaged.
 
Thanks all! Have a great day/night where you may be!

Last year I had a very similar problem. Troubleshooting revealed that the pan controls in the mixer applet for my audio interface were not set correctly. Check your meters in Sonar - when you do a hard pan, do the meters show anything on the opposite channel? If not, then it could be your audio interface pan controls.

Thanks for the input!
 
Oddly enough, at 96% panning I do show activity on the meters for both channels. At 100% only the properly panned channel shows activity (but I obviously have audio in the channel that should be silent).
 
This particular audio interface unfortunately does not have it's own control interface except for a very limited buffer control in the ASIO control panel. Honestly, something screwy with the audio interface settings is exactly what I thought was the likely culprit but I can't figure out why exported audio exhibits the same problem even when played back from a different device altogether...
 
I'll continue to poke around and mess with drivers. I'm going to do a manual uninstall of all Focusrite drivers to see if that helps. In the meantime, additional ideas/comments are very welcome!
 
Thanks again!

You can eliminate both hardware and drivers, neither of which play a role in exports. Whatever's happening is happening entirely within SONAR. My next test would be to remove (not just bypass) every plugin and export that version of the project.

Do you have any stereo FX sends ? By default Stereo FX sends for FX, Exc are straight up and don't follow track panning.
Make sure to pan the send as well unless you want the stereo bleed.
 
A good way to test is to bypass the FX send.

There was a thread along the same lines a while ago...maybe a couple years. I forget what the solution was, but it was solved.

Thank guys. I first noticed this in an older project and to remove variables I started a completely fresh project with literally nothing but two mono audio tracks in it; the problem persisted. The project was not based on a project template and therefore was completely blank with absolutely no FX/plugins/softsynths added. There are no effects loops, inserts or sends in place either.
 
At this point I'm going to open a support case with Cakewalk as I am fully convinced this is one hundred percent a Sonar issue (and a new one at that). If anyone is feeling generous I'd be curious to know if you can duplicate it.
 
Thanks all!

Thanks man! I'll keep digging. The forum search refuses to work for me so that makes things a tid bit difficult to find... I'll see if it's a browser issue.

Use Google for searching, e.g. "SITE:forum.cakewalk.com {keywords}".
 
I'd be glad to look at your two-mono-track test project. Post it on DropBox or something.
