I have the following in my setup:
- Push 2
- Komplete S61 Keyboard
- Mackie MCU
For controlling devices with ease Push is the best and most used gizmo I have followed equally by my beloved MCU which kind of does everything control wise but I wouldn't recommend it unless you know why you need it.
The iPad and Touchable are neat but I actually rarely use it. The features are great but honestly the interface to me seems cluttered and just too much going on and though it works for me flawlessly (havent tested in 9.5 tho...) when I am playing and just want to reach for a tweak of my attack or a filter sweep it's a tough thing to achieve reliably while playing with one hand and trying to flick through pages and get your finger in the correct position. Downside of touch. I use it mainly as a way to control a few things from where my Keyboard is away from the monitors.
The K61S (once you do the setup for your Live set and instruments) is great and there are simply some things I prefer the keyboard for.
Almost all "auto mapping" controllers will limit you to the 8 controls so if you want real tactile control over all your ADSR and filters at once then you will be looking at a solution you will have to manually map. I use to use a Korg nanoKontrol for direct device mapping but rarely bother now because the lack of any display or feedback makes it tough.
I would absolutely Love something like this:
But not that specifically. Something like Push but with lots of controls and feedback
