With Classic SmartMusic it was possible to import smxp-files that included audio files. This way we were able to produce very nice sounding and professional accompaniments. To accomplish this we added an audio track to a finale notation file. The audio files were created via Band-in-a-Box or GarageBand Loops and occasionally real recordings.
We really need this feature in New SmartMusic again. We need to be able to import SM-Files that include audio tracks. It is very important to our students.
