The latest MegaDrumManager version is now 20150614.

In this MDM version handling of configs has changed.
Each MDM config is now mapped to a file so when you switch between configs with prefvCfg/nextCfg or selecting a config form the dropdown list, MDM actually tries to load a config from a file mapped to this config.
A file is mapped to a selected config when you do 'Load All' or 'Save All'.
When you switch to a config which doesn't have a file mapped to it yet, MDM will show '??' in red next to the dropdownlist.
When you switch to a config which already has a file mapped to it but the file doesn't exist (deleted/moved), MDM will again show '??' in red next to the dropdownlist.
When you switch to a config which already has a file mapped to it, MDM will show 'Ok' in green next to the dropdownlist.
A file name of a file mapped to a config now means the name of a config.

MegaDrum internal configs are now called Slots.
MDM will show number of available slots in MegaDrum in 'SlotsCount'.
MDM will show current slot in MegaDrum in 'Current'.
MDM will show name of a slot in 'Slot Name'.
