ive got a remote 25sl, you might find it useful for performance what you can do with the template editor.
if you divide up your instruments with midi channels, you can program 16 different templates on 16 different channels and assign 16 buttons to change to those templates. best way to do it is just make one template, program those template buttons, copy the template 16 times, and then set the channels.
if youre willing to spend some money what i would really recommend is buying a maschine. theres still plenty of mk1's available for 350 last i checked. the browser is great, programming is great... you might be under the assumption its only for making beats but combined with your keyboard you might find that its the perfect solution for browsing, editting and selecting patches with the computer completely out of sight
