When loading pre-SONAR 4 projects in SONAR 4, please be advised that the Track Interleave toggle behaves differently in SONAR 4, which may result in your pre-SONAR 4 projects sounding a little differently.
In SONAR 3.11, the track interleave button implicitly specifies the input interleave if the effects bin. It has no effect on the actual data streamed out of the track bus when no effects are present.
In SONAR 4, track interleave button actually specifies how the data is streamed to downstream buses. For example, you can now switch a stereo track's interleave to mono and it will send mono data from its output (or sends) to all downstream buses. SONAR 3.1.1 doesn't do this- it ignores the track interleave button unless effects are present.
This change will potentially make a SONAR 3.11 Project sound different if it was saved with the interleave button set to mono but no effects were present in the effects bin. If this is an issue, and you need the project to sound the same again, simply set the track interleave button back to the desired state.
