“Your ever-growing collection of boutique modular gear, vintage synths, and software instruments can finally perform in unison, thanks to the jaw-dropping connectivity KeyStep Pro has to offer. KeyStep Pro makes gigging easy and fun, with instant and intuitive access to inspiring performance features. Multi-mode arpeggiator, randomness, easy chord mode, and real-time recording for creating on the fly. The crisp OLED displays and LED-illuminated controls will help you see it all in the dark, too.” - Arturia


Arturia's Keystep Pro inherits the best elements of the popular Keystep with a slew of advanced editing options and connectivity upgrades. The 37 slimkey keybed (expanded from the Keystep's 32) is upgraded with LED above each key for visual feedback. The step sequencer is is spread across 4 tracks with 64 steps and 16 note polyphone (upgraded from the Keystep's 8) and advanced editing of individual steps, patterns, scenes and chains. There are 4 outputs for connecting to your vintage gear via CV/Gate/Mod and 8 individual drum gate outputs. In addition, the Keystep Pro also boasts an onboard 7 mode arpeggiator, chord mode play (play a chord and reproduce it across the keybed), sustain hold and pedal input, pitch + mod wheels, and more. The Keystep Pro is one of the most versatile controllers for use in combined hardware + software studio applications we've seen.
