To fix the problem wit the import problem there are two solutions.
#1 simply update your Logic Pro x (garage band also) to the latest version. This update was made to fix the problem (bugs) the new Mac OS Catalina update cuased.
#2 (for my cracked Logic users)
- update your garage band to the latest version.
- Open a new audio project in garage band, or any software able to convert mp3 to wave.
- import desired audio file into garage band (or other software ex. audacity sonar ect.)
- export the entire project as wave file.
- Open Logic Pro x import the file you just converted to a wave or.
- Drag and drop into logic an this should fix the “chipmunk effect”
(In garage band select share song, share to disc, select “wave” as the type of file to export an export to a place easy to find the file!)
Import desired audio
(in audacity select file, export... when asked to save make sure to save as wave file. Export to a place easy to find the file)
