Step-By-Step Guide for using the Remote Control Editor

I’ve just bought an Akai MPD26 and am wondering if it’s possible to use it with the Remote Control Editor? I’m new to Midi-mapping so it’s a steep learning curve at the moment - I’ve got the MPD26 set up as a generic remote in the devices menu, and it’s working in the mixer, also I’ve set it up to control the transport (using MMC). From reading your post I’m assuming it’s not possible to use it with the Remote Control Editor, but I wondered if there is another way of mapping it to Cubase and 3rd party VSTs? Many thanks!
