The BCR2000 SysEx capabilities are hardly covered by the official documentations and tools. I guess nowadays such controllers are mostly intended for use with software, to control DAWs and plugins. But they are equally ideal to control those 80’s to 90’s digital synths, which lack hardware controls but provide parameter setting via SysEx messages.
The BCR2000 is perfectly capable of that, but you have to know how to set it up. You can always use the learn function to assign a SysEx message to a control. If the SysEx message is simple, the BCR will perfectly recognize it. For proper setup however there is a perfect tool out there called BC Manager. It needs a while to get used to the interface, but you can edit and control every aspect of the device with it, send and receive data and manage multiple devices. A must-have for every BCR owner!
If you want more information on the SysEx capabilities of the BCR, check out the resources and links on the Mountain Utilities BCR/BCF page, too.
