Arturia AstroLab 37: Compact Powerhouse for the Modern Stage

Arturia introduces the AstroLab 37 as a compact, expressive stage and studio keyboard, targeting musicians who want the sonic depth of Arturia’s software instruments in a portable, hardware-centric package. The video positions the 37-key model as both affordable and performance-focused, highlighting its suitability for travel, rehearsals, small stages, and tight studio spaces. The core pitch is clear: you get the full sound library of the larger AstroLab models, but in a form factor that’s easy to carry and quick to set up.

AstroLab 37 is presented as a versatile addition to any rig—capable of serving as a dedicated bass, lead, or texture keyboard, or standing alone for more comprehensive duties. Arturia’s approach here is to democratize access to their V Collection engines, making them available in a streamlined, gig-ready device. The emphasis is on immediacy and portability, with the instrument designed to slot seamlessly into both stage and studio workflows.

AstroLab 37’s sound engine is built around a curated library of more than 1,800 presets, spanning a wide range of synthesis techniques. The video underscores that many sounds are inspired by iconic analog and digital classics, while others explore modern approaches like wavetable, FM, and hybrid synthesis. This breadth is demonstrated through a selection of presets, showcasing everything from lush pads and expressive leads to punchy basses and evolving textures.

The instrument is positioned as equally adept at delivering traditional sounds—such as pianos, electric pianos, and organs—as it is at more experimental timbres. Preset switching is described as immediate and performance-friendly, with each sound tailored for musical playability rather than static computer-based editing. The workflow focus is on quick access and musical expressiveness, ensuring that the sound palette is both deep and accessible in live or studio contexts.

AstroLab 37 brings a trio of performance features to the table: arpeggiator, chord mode, and scale mode. The arpeggiator transforms simple chords into rhythmic patterns, with real-time access to direction, octave range, and timing—making it a flexible tool for spontaneous idea generation. Chord mode allows users to trigger full harmonies from a single key, with the ability to record custom chord shapes on the fly, streamlining complex voicings for live play.

Scale mode is designed to lock the keyboard to a chosen scale, ensuring that improvisation stays harmonically grounded and in tune. Together, these features are presented as essential for creating evolving patterns, melodic hooks, and harmonic textures in real time. The workflow here is about reducing barriers to creativity, letting performers move quickly from inspiration to execution without menu-diving or programming detours.

AstroLab 37’s connectivity suite is robust, covering both traditional and modern needs. The back panel features MIDI in and out, a sustain pedal input, a mono audio input for processing or vocoding external signals, balanced TRS main outputs, and a headphone output. This ensures compatibility with a wide range of studio and stage setups.

On the digital side, USB-A supports controller power or playlist storage, while USB-C connects the AstroLab 37 to computers or mobile devices. Wireless integration is available via Wi-Fi and Bluetooth, allowing seamless connection with AnalogLab and the AstroLab mobile app. The overall design is about flexibility—whether you’re integrating into a DAW-based studio, a DAWless hardware rig, or a hybrid live setup, the AstroLab 37 aims to slot in without fuss.
