This Max for Live device lets you select songs (‘Scenes’) in Ableton Live Session View via selecting kits on your Roland SPD-SX or SPD SX Pro (yes it works with both SPD SX versions!).
Please check out the video below to understand on how to set this up. (The video has chapters so you can skip to the points in the vid which are relevant to you!)
You will need to activate a few things in your SPD SX / SPD SX PRO to make this work! (All explained in the video!)
