Solid

Not seen much discussion of this bit of kit on the internet, especially in regard to its use with Live, so I'm gunna jot some thoughts down here. It's really solidly built, which is refreshing considering generally MIDI controllers (at least ones I've had experience with) feel cheap and frail compared to most other music hardware. The encoders and faders feel amazing, and the way the encoders transmit information is really clever; if you turn more slowly, it will change parameters in smaller, more detailed increments, and if you turn more quickly, it will change parameters in larger increments over the same throw. This feels really natural, like it's matching your movements. The buttons are also nice to press and not noisy or clacky.

Its integration with Live is amazing, the control script is really well thought out and using it with the controller is intuitive. I bought this to replace a NanoKONTROL2 with its Mackie Control script and it's a massive upgrade. I wanted a single controller to control everything I needed to in Live (mostly rack macros and the navigation of an arrangement-based set with markers) and this seems quite adequate so far.

It can't do absolutely everything, you're limited to controlling the volume of only 16 tracks over two 'set-ups', and I had to manually map marker navigation to some of the buttons I wasn't using, but I don't think any controller can do it all, even a Push. However if I would have liked anything added to the script, it would be a way to control the volume of more than these first 16 tracks. I would also have liked the actual chassis to have been made of metal to add a bit of weight, although this is personal preference. A button to fold / unfold groups would be cool too.

In conclusion, in this form factor, the build quality and functionality far surpasses anything else I've tried. It's a bit expensive but I'm happy, and Mathias at Faderfox seems like a nice bloke and is responsive to e-mails which is reassuring.

cheaper alternative

A cheaper way to access a bank of knobs and sliders, but lacks dedicated MIDI out, endless encoders and an in-depth control surface script for softwares like Live. It also has a lesser build quality, but is perfectly adeqaute for a manual mapping set-up.
