Notes: * ADL: The DMX volume model was set as default to unify volumes on all bank. Otherwise, if you will use 'Generic' or 'Win9x', the sound will became too loud than wanted. Each bank has own default volume model which is used when 'Auto' is set. * ADL: 6 chips is optimal to work with default banks * OPN: 8 chips are set to provide 48 polyphony channels. (each OPN2 chip has 6 channels only) * Text files: junk spaces from end of lines are was auto-removed.
