Provide 9-10 stems. Make sure to separate out the kick and bass as a first port of call (ideally make sure kicks and bass are mono!).
Group together things like:
Percussion (rims, hits)
Snares + Claps
Tops (hats, rides, shakers)
The stems should be exported as you would export a pre-master (i.e. individually, not through the master bus with any processing) but you should include processing/fx on the individual channels.
Please leave *around* -6dB of headroom on the master output when you export the stems and select ‘all individual tracks’ in Ableton.
44.1kHz sample rate (minimum) / 16 or 24bit (24bit preferred).
