Review: Excellent Product for my needs - Session Drummer 3 in Sonar X2 - Arrived very quickly, excellent price, very high quality and beautifully functional. Downloaded editor and set up patch 60 to drive 8 MIDI drum patterns in Sonar's Session Drummer 3. A little bit confusing over note numbers. Working brilliantly using front 8 switches. Will use 5 rear switches for individual drums. Unit can do much more than this! Robust, compact, clear bright lights on switches. Extremely pleased. Obviously a product like this is for particular needs, so advise researching and making sure you know how you would use it. There are alteratives, but I have separate expression pedals, so this complemented them well.
Review: A device straight from Star Trek - I always imagined a mixer where the channel faders were actually the LED VU meters themselves but until the KMix this was just an idea straight out of science fiction. This is one of those rare devices that works exactly how you hoped it would. Although Windows support was a bit delayed after its initial release, it is rock solid under Windows 10 as an 8 input, 10 output audio interface and you can set buffering to permit fairly low latencies, around 5-6ms on a not-particularly powerful laptop, playing instruments through Reaper. I've had this unit about 3 years now I think and it has never ever malfunctioned in any way. It was a thoughtful touch that the headphone output is configurable as a separate stereo pair of outs, which makes this perfect in a home studio. It's also the first audio interface I've had - of several over the years - where noise due to ground loops is completely absent, the preamps are very quiet. As a bonus, it also acts as a control surface, which means that within Reaper I can control mute, solo, channel gain, pan, transport and scrubbing as well as switch between plugins directly from the KMix. The control surface plugin for Reaper is completely free (search kmix reaper to find it). You can just switch between control surface mode and mixer mode from the unit front panel, which is very handy. The only very minor negatives I could raise would be that the button legends are quite small though of course backlit and that the preamps could benefit from a switchable attenuator for very hot signals, but that's nitpicking since obviously you can just plug an inline pad into a channel in that situation. It would also be great if KMI ever produce a version where all 8 input channels can handle mic and line inputs, at present you have two mic/line channels and the rest at line level, but this is pretty much the case for most audio interfaces anyway, and you can always hook up an external preamp if you needed more mic-level channels. The mixer is very capable, with inline parametric EQ, noise gate and compressor on every channel, and they work extremely well. Also it supports multiple switchable 'scenes' so you can save an entire setup and recall it at the touch of a button - the sort of thing only available otherwise on high-end digital mixers. There is nothing quite like this unit on the market and considering that an audio interface with this number of ins and outs is already getting close to the price of the KMix, given you also get a decent mixer and control surface included, in something the size of a paperback book, with no moving parts, hence, rugged and reliable - well, what's not to like. One of those rare products that I have not been disappointed with in any way.

## Questions & Answers

**Q: Is this compatible with an IPad?**
A: i did not get a chance to try it but that is my understanding.

**Q: How does this compare to babyface, irig pro, apogee duet 2 and zoom h6? i want a portable interface to record with my ipad pro on the go.**
A: I use mine on a Win 10 Surface pro 4, so I don't know about the irig pro.  The apogee would probably have better A/D converters, but it's only two channels, and you have to buy plugins for some of the better console emulation.  I would put the sound quality well ahead of the zoom unit.  It records 8 track audio pretty easliy, the 2 onboard preamps sound very good, and the k mix also functions as a standalone audio mixer.  It's built like a tank, and with no moving parts to break off, its a great live recorder.  Again, i use it on a windows system, but it was developed for apple devices.  It can mix in multiple surround configurations, it slices, it dices, it makes julienne fries.  For the money, i recommend it highly for mobile multitrack recording.

**Q: What is the sampling rate? It says 32 bits, what rate? 196 and I’d be impressed**
A: I believe it depends on your computer. You can consult the user manual for more technical information

### ⭐ Unreliable USB, unreliable sliders, what a shame ...
*by A***X on 24 December 2020*

I'd always wanted one of these, but what a disappointment. I'm gonna keep this short, but basically I sent it back and got a refund. The faders are rubbish; you have to press really hard to get them to move and are totally imprecise; also one of the faders wouldn't got to zero unless you gave it a really hard thumb push; totally unreliable. The USB connection would work sometimes; not others; so just couldn't rely on that either. The pads are multi-touch; but not simultaneously; so you cannot use this as a proper Ableton launchpad. I could go on. Personally, I think KMI should have had a new edition out a long time ago which fixed a lot of these problems. Also note that KMI sell reconditioned units for under half price. I see these are 'out of stock' now. So, gutted about the product, but happy with the way KMI and Amazon dealt with the refund!
