The Arturia KeyStep Pro is a successful combination of Arturia's cult controllers KeyStep and BeatStep Pro. A velocity-sensitive keyboard with 37 keys, which also has aftertouch, is the primary means of recording melodies, basslines and drum triggers. Here you can also use the TR grid to place your beats on the spot. Four tracks can be played in parallel and output their notes and commands to a total of two MIDI ports, eight drum triggers and four CV/Gate/Velocity outputs. The control voltage outputs of the Arturia KeyStep Pro can be linked together; this makes it possible to play a lush modular system in four voices. Of course, polyphony is also output via MIDI. The analog clock/reset inputs/outputs can be used to synchronize a drum machine from the pre-MIDI era, a Teenage Pocket Operator or the sequencer of a modular system, for example. The metronome built into Arturia KeyStep Pro is output as an audio signal and can be conveniently monitored via the mixer or headphones. An arpeggiator and a random function round off the controller, which has been optimized with a focus on live and direct access.
Using this as a (just about!) mini keyboard into my Mac with Logic and iPad, as well as a modular setup. It’s a lot of fun to use and I’m now getting it into muscle memory and it’s becoming a serious device that I can’t do without. Great solid quality and value for money.
I'm using it for a year now and I like it very much.
The connectivity is just amazing, every output can be individually setup via the software. V/Hz for my MS-20, has of course eurorack setting and also Buchla 12v.
Has also v-trig and s-trig.
I use it to sequence my pulsar-23, ms-20, minilogue, Vermona DRM mk3.
It has only 2 midi out but I use a Kenton MIDI Thru 5 and it's perfect.
Midi out 2 can now be setup as a MIDI Thru.
The workflow is a first a bit weird to decipher, but after watching a couple of tutorials, it's pretty easy to use.
I would recommend to use the software to setup MIDI channel, CV output style and trig. It's doable using the tiny screen but rather annoying.
The build quality is pretty good, it's not build like a tank though.
Pretty funny arpeggio and sequencer randomization.
Pros:
_connectivity.
_ease of use. Every option get quickly into your muscle memory. No obstacle to inspiration.
_Nice arpeggio and one can transpose every track all together, or only the selected ones.
_build quality (I like how the mini keys feel).
_let you create your own scales.
Cons:
_No micro steps for ratchets.
_it's pretty ugly.
_could not get negative voltage from the mod touch-wheel.
