If I copy and paste a track within or between projects and the original track has mono interleave, the copy has stereo interleave. This matters if the original track is panned away from center (e.g. 100%L). The track is now 3dB quieter because I use the default pan law.
 
It seems Copy/Paste Special doesn't preserve the interleave. Is this right, or a bug? Clone track does preserve the interleave, but I can't use this between projects.
 
Cheers, Peter.
 

Does the pan law come into effect here?
 

Absolutely. I mentioned this happens under the default pan law. It doesn't happen under the "balance control" law. Haven't tested the others.
 
I think that Copy/Paste has a bug - it fails to copy the interleave state, even though it copies the phase, volume, pan and seemingly everything else.
 
Cheers, Peter.

But when you copy a track between projects, you are copying the contents whether it's audio or midi.
It doesn't copy sends, prochannel modules used, volume, pan, etc. why would it copy the interleave setting?
(unless I'm misunderstanding you)

I'm talking about Copy Special and Paste Special. These commands transfer volume, pan and phase. I would expect them to transfer interleave as well. Otherwise the copy can have a different volume to the original. However, as you say, sends are not copied, nor are inputs/outputs (even if the bus exists in the new project). I haven't tested PC. Finally, I just noticed gain isn't copied either. Seems like there are some inconsistencies here.
 
Cheers, Peter.

If pan law says -3dB center - that is what happends to mono tracks.
 
There usually is a 0dB alternative also, don't remember about Sonar what they are called.
But that also means you will feel you loose energy when panning from center.
 
And there usually is some logarithmic alternative too - might be the balanced one.

AFAIK, Copy & Paste Special does not pick up Pan, Phase, Volume or Interleave.
 
The pasted information always inherits the parameters of the Destination Track.
 
If you're seeing something different it would be useful to describe exactly what you're doing, step by step

OK, try this:
1. Start with a new blank project.
2. Add a track, ensuring the input is a mono source.
3. Enable record and record a few seconds of silence.
4. Set volume, gain and pan to something random (not zero).
5. In the track inspector, set the interleave to mono and the phase to inverted.
6. Select the track and copy using ctrl-alt-C (shortcut for Copy Special)
7. Paste the track using ctrl-alt-V, choosing a new track in the paste dialog
8. A copy of the original track appears as track2.
 
Now, which settings (out of vol,gain,pan,interleave,phase) copy correctly, and which don't?
 
Cheers, Peter.

7. Paste the track using ctrl-alt-V, choosing a new track in the paste dialog
 
This is the part that will cause the destination track to inherit the source track's properties
 
If you insert a track before the paste whatever parameters the inserted track have will be preserved after pasting.

Any reason to not to simply clone the track?

I'm also thinking whether you needed to copy the track or copy the clip?
