If you mean aftertouch, yes it has channel aftertouch. If you mean are they capacitive rather than physical keys, no -- these are slim synth-style keys that you depress to play, not capacitive like a smartphone screen. **Q: What is the height of this keyboard, including knobs? I'm considering getting one of these to use on a keyboard tray with only 1-7/8" clearance. Thx.** A: 2" **Q: How many peak watts does this run at?** A: The device is labeled "12V DC / 1.0A" which is 12 watts. I have no idea what the normal or average consumption is. **Q: Will this work with my Polybrute?** A: It will work with anything that accepts MIDI or CV. I don’t have a polybrute but I would be surprised if it did not have MIDI. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The glue *by A***R on January 20, 2026* 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! *by G***E on July 16, 2025* Very fun controller. Opens up many avenues to music creations. ### ⭐⭐⭐⭐⭐ My cat loves the Vegas lights (and I kinda do too) *by B***E on April 8, 2021* 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. ## Frequently Bought Together - Arturia - Keystep Pro - All-in-One Performance MIDI Controller, Sequencer and Arpeggiator - 4 Polyphonic Sequencer Tracks, 24-Part Drum Sequencer, MIDI & CV Connectivity, 37-Note Slim Keybed - ANALOG CASES Arturia KeyStep Pro/MiniFreak Case - Custom-Fitted Compact PULSE Hard Case for Travel - Mellbree MIDI Cable, 2-Pack 3-Feet Male to Male 5-Pin MIDI Cable Compatible with MIDI Keyboard, Keyboard Synth, Rack Synth, Sampler, External Sound Card, Sound Source and Other Music Gear --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/218594222-keystep-pro-37-key-controller-and-sequencer-usb-midi-cv](https://www.desertcart.pl/products/218594222-keystep-pro-37-key-controller-and-sequencer-usb-midi-cv) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
