Greetings all,
Don's link leads to this:
(Take note of the "NOTE")
"To edit audio from Cakewalk Sonar X2 / X3 in RX 4:
Right-click the clip you wish to edit in RX and select “Process Effect > Audio Effects” from the right-click menu.
Select RX 4 Connect in SONAR’s plug-in browser.
When the RX Connect plug-in window appears, select either “Reference” or “Repair” and click “OK” to send the clip to RX 4.
NOTE: Do not click the Audition button, as this will send only a portion of the clip to RX 4.
Once you are done editing in RX 4, click the “Send Back” option on the file tab.
Repeat step’s 1-3. This time when you click OK in the RX Connect plug-in window, the repaired audio will replace the original audio in SONAR’s timeline."
The Utilities menu option is a lot less step intensive, but as I mentioned - it's been problematic as of late.
...though... I find it odd that issues have arose just as a new version of RX arrives...
Regardless, seemless transfer out to an editor and back again is something I do quite a bit, and worth it's weight in gold,
so I may bite the bullet and get the Advanced upgrade...
