I can't really say to much about it yet, as I have just started using the Maschine Mikro and the Maschine software, but so far it's working great, especially for a used piece of hardware.
I really should have bought the Maschine.. I think Maschine Studio would be amazing! The software is pretty decent, the sounds are great. I only dislike the hardware..but that's my own fault for buying it :)
The Native Instruments Maschine Mikro was the first sampler MIDI controller I owned. The first thing I noticed is it's got beautiful light up pads and buttons which you can color-assign to keep all of your samples, groups, patterns, and scenes color coded and organized for easy recognition during recording or performance. Another aspect I like is the highly velocity sensitive pads, which give you much more control over your sound when say playing notes or finger drumming live. I have a lot of issues with the Maschine program, mainly in the way they set it up, as well as there are some features that shouldn't have been removed during transition from the 1.0 to 2.0 softwares. Luckily using the Maschine Mikro controller with the 2.0 software is even easier and more fluid than it was with the 1.0, and even though I have issues with the software itself, Native Instruments did a good job of making their controller and programs work together seamlessly. Another thing I like about the mikro is that you can do anything that you could do on-screen in the software, with the controller and it's display pad, well besides adjusting levels in the mixer. One of my issues with maschine is that in the Group view you can only see 8 groups at a time, even though you have 16 pads. If they allowed to 16 group view at once then the user wouldn't have to scroll back and forth nearly as often to automate things like solo or mute commands or fx over groups.One last issue I have is that the dial is a click dial instead of smooth turning dial, so automating effects like a filter or ice doesn't fade smoothly. Overall the controller is a well made, easy to use, and innovative production tool, that greatly speeds the workflow in my production.
