Arturia MIDI Controller 430321 Editorial Review
Arturia - Keystep 37 MK2 - Portable MIDI Controller, Sequencer And Arpeggiator - 37 Slimkeys, OLED Display, Polyphonic Step Sequencer, 16-Mode Arpeggiator, CV-Compatible - White features a solid build quality and intuitive controls which enhance the user experience. The OLED display is particularly noteworthy, providing clear information during use, which helps streamline setup and performance. Many users appreciate the ease of assigning MIDI CC controls directly on the device, making it a great choice for those integrating with outboard gear. While this model offers significant upgrades, such as added sequencing options and creative features, it's worth noting that it no longer includes the transpose function from external MIDI, which might not suit everyone's workflow.
