Keith MCMillen K-737 K-Mix Audio Interface/Mixer

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!

Not fit for purpose. In order to connect to a midi synth, you need to pay an extra 55 or so quid for the 'midi expander'.

Absolut innovatives und geniales Musikinstrument. Benutze es vor allem als Drum-Pads, und zum Fingerdrummen ist es schon einiges angenehmer und präzier als z.B. das Akai MPD-24, und ist sehr sensibel mit den Sensoren beim Anschlag. Aber man die Pads auch nutzen um 3 verschiedene Steuersignale an Synthesizer zu senden: Druck und Fingerpositionen links/rechts und oben/unten, damit kriegt man geniale Klänge hin. Einziger Wermutstropfen ist die Verwendung von MIDI: 128 Stufen sind einfach zu wenig, man verschmerzt's, aber ich will einfach mehr Auflösung haben, mindestens 14 bit (16384 Stufen). Es gibt schon den Rohmodus mit 1024 Stufen aber der ist aufwändig zu bedienen. Desweiteren ist USB-MIDI bezüglich der Latenz murks, was man ganz gut merkt, wenn man Realtime-Linux (RT_PREEMPT) verwendet, da ist der Jitter schon spürbar. Mit dem MIDI-Expander und einer guten Soundkarte klaptt das zumindest einiges besser. Ich bin trotz dieser Einschärnkungen dennoch super happy mit dem Gerät, so für einen kleinen Spassjam unterwegs Leute beindrucken ist das Ding genial.

Me ha gustado la rapidez y seriedad de la transacción. Pero no tengo claro que el producto funcione perfectamente, no he conseguido configurar ni las funciones básicas. Tengo experiencia en el mundo de la informática musical y después de varios intentos he decidido devolverlo.No es intuitivo, demasiada programación y los pads me parecieron demasiado pequeños , no se distingue bien cuando pulsas, hay un proceso de adaptación demasiado largo para mi.

I never write reviews but this one deserves it. I bought this for OBS to change scenes and control chrome/acrobat/logic at the same time while playing guitar. I tried first with midi commander, but it froze all the time, and only offered 8 buttons per bank. This has FORTY possible foot switch options per bank, and they are silent! I’ve never seen anything like it before. The recordings I did with the other pedal are almost ruined because of the noise it made switching scenes. The ease, speed and dexterity this allows in navigating was well beyond my expectations, I can feel exactly where am without looking, and without making mistakes. The possibilities this has opened up for me with streaming/recording are huge. As for the reviews about it being so hard to program, I took an hour to read the manual and had it done within the next. Downsides, expensive and was long to arrive, but when it did it was like Christmas. Recommended.
