wine users - Oct 2001 - Midi sequencers

i'm trying to run cakewalk, it's a midi sequencer but i have an error.
what is a WinMM section?


error messages:
------------
err:mmsys:MMDRV_InitHardcoded You didn't setup properly the config file for 
the Wine multimedia modules.
Will use the hard-coded setup, but this will disappear soon.
Please add a WinMM section to your Wine config file.
