Hello Arturia Forum Admin (whoever you are),
Could you implement a new area for community users called (something like) File Exchange for stuff like MCC User Bank exports, Analog Lab MIDI mappings for 3rd party controllers, special MIDI mappings for Software Instruments, etc.? I think that some kind of naming convention would be needed also once this is created.
As far as sharing sound presets (e.g. for specific song covers), it’s be a great idea to implement something that mimics Yamaha’s SoundMondo (without getting too carried away). Just a well-structured/named area would be nice. The area could be called Preset Sharing.
EDIT:
A mechanism to store the files would be needed to avoid Community users from having to setup their own sharing. It might make sense that the Forum web app would only be allowing file types supported by Arturia software.
