I'm glad experimenting with the new RT's and new features with the new 2013 version.
The new sounds are great!
But I came up with a problem as I opened some of my songs which have tracks with another synth (for the thru part):
The songs loads - but not the synth for the thru part. The error message shows up saying:

"Invalid track number. Unable to load synth preset to track 8."

Seems for me that this is only a problem with another synth of the thru part, not for other parts. But I'm not quite sure on that. For sure is that this the case for my favorite two synths: Kontakt 5 and Pianoteq 4 (try this one for exellent piano sounds!!! Tip: You should really download the free trial version!!!)

After the songs have loaded the other tracks, it is possible to assign my favorite synth patch again to the thru part. But all its specific settings I had stored along with the song are lost! I would have to arrange them anew for lots of songs.
Please help me with a fix in another new build! Thanks!
