ArturiaKeyStep Pro 37-Key Controller & Sequencer USB/MIDI/CV Keyboard Controller, with Aftertouch, 4 Polyphonic, 16-Track Drum Sequencer

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.

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

Really, really well built. Very beautiful, keys are very smooth.Perfect size for me. Works really, really well.

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.

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.

Arturia never disappoints, and this is no exception. Tremendous power for the price.

So I'm new to midi controllers but this thing is blowing my mind. Have a Yamaha AN200, Behringer TD-3 ,and Roland's tr-8s. I can't believe how much it can do how easy it is to do it.

Four sequencers and just great to have fun with. Keys are too small for real keyboard feel, but fine for sequencing. Lots of features, a gas for this kind of gadget.
