Stems requirements

Preparing Stems can take some time, and depends on the file type, track length & the specifications of your device. 

For the best performance results when using Stems, it is recommended that:

• Your music library is analyzed, with no corrupt files.
• The 'Analyze Stems On Song Load' feature is enabled. 
  (Settings Icon > DJ Preferences > On Song Load > Analyze Stems.)
