The glue
Rock solid build, intuitive layout, and excellent connectivity. It makes controlling multiple devices simple and keeps ideas moving without getting in the way. Easily one of the most useful pieces of gear in my setup.

Very enjoyable!
Very fun controller. Opens up many avenues to music creations.

My cat loves the Vegas lights (and I kinda do too)
I ordered this along with some rather heavy clamps for wood working, and they were shipped in the same box. This box arrived having bright USPS tape stating explicitly that it had been damaged in shipment. That said, my first impression is that this is a well build tanky bit of kit since the only actual damage was a slight puncture in the box; absolutely zero damage to the item itself. If any blame is to be assigned here, it would be toward Amazon for working people to the point that they can't even tape a box shut properly. The MIDI controller itself seems to work well so far. For testing, did some routing into VCV Rack then out via rtpMIDI to MainStage, then back into VCV again over audio connections (using separate PC and MacBook). It all worked with very little latency, I'm looking forward to what else this thing is capable of, especially when it comes to actual Eurorack rather than just the virtual test. ... show more

Very glitchy product
I'm not sure if I'm pushing this thing too hard with my setup or what, but I'm extraordinarily disappointed by how glitchy the KSP is. For context, I'm not a noob when it comes to MIDI setups, and I'm a compulsive "saver"...as in saving the projects, scenes, patterns, etc. after most changes. My firmware is up to date too. Freezing when I paste patterns too quickly, randomly forgetting scenes or patterns that I've saved, etc. When it works, it's fantastic. It's totally possible mine is defective, but I'm getting the feeling this is just how it is. My intuition is this: if you're using it to create DAW-less house jams and enjoy it as a creative "toy", you're probably alright. If--like me--you're using it to chain together actual songs (e.g. verse, chorus, verse, bridge, etc.), I would not recommend. I'm going to give it another go tomorrow, but unless something radically changes, I will be selling this for sure. ... show more

Best thing since sliced bread.
Truly the best piece of equipment produced in a long time. Way more connectivity than you will ever need and an easy interface once you read a little of the manual. Only down side is the key size. However, bigger key size would mean a bigger form factor which would mean a more expensive product. Price is just right for what it does. ... show more

Not what I expected
I've had this midi sequencer keyboard for two years. It is NOT easy to use. I barely use it because it requires too many steps and button-pushing to get it to do anything. Maybe this was designed for studio-engineering rather than live performances. It is not intuitive at all. I was disappointed by it. I've watched how-to videos, tried different setups, and it blocks my inspiration. I like other Arturia products, but should have opted for simpler options. ... show more
