i could be wrong but you might need the akai afx for all that, or at least a secondary controller mapped to those functions, for an example i have my twister mapped to activate different sized loops on pressing an encoder down and if i need to resize it i have an encoder mapped for that as well, and as far as fast forwarding, im not sure how you would do that, the afx has a touch strip to pin point a location in a song though , or if you have a touch screen you could do it that way
:edit, if you select the midi learn function there is a per deck fast forward button that can be mapped
Indeed I am - your base work is amazing!
I’m going to contribute a clear manual that extends on your own, a list of midi messages, and a list of modifiers (that I reversed-engineered)
