Arturia AstroLab 37: 44 Synths in One Compact Keyboard

The Arturia AstroLab 37 packs a staggering 44 legendary synthesizers and over 1,800 performance-ready sounds into a remarkably compact and affordable keyboard. Designed for musicians on the move, this portable 37-key instrument delivers the core experience of Arturia’s acclaimed AnalogLab software in a dedicated hardware unit, eliminating the need for a computer during a live set. While it prioritizes immediate access to a vast sonic library over deep sound design, it represents a significant value for players seeking a versatile and reliable instrument.

Unlike a traditional synthesizer built for sound creation, the AstroLab series functions as a stage keyboard, focusing on delivering a curated collection of presets. This approach is ideal for gigging musicians who require a wide array of high-quality sounds at their fingertips without the complexity of programming. The larger 88-key and 61-key models launched first at premium prices, but the AstroLab 37 brings the same powerful sound engine to a much more accessible price point.

The magic of the AstroLab lies in its direct connection to Arturia’s renowned V Collection. This software suite contains meticulous emulations of iconic and often prohibitively expensive instruments like the Yamaha CS-80. The AstroLab hardware effectively serves as a “greatest hits” browser for these sounds, offering the essential character of these classics in a streamlined, performance-focused format.

You are provided with an extensive library right out of the box. The AstroLab 37 comes preloaded with sounds spanning acoustic pianos, analog legends like the Minimoog, and distinctive digital machines from the 1980s such as the Ensoniq SQ-80. The quality is generally exceptional, with standout emulations like the Rhodes electric piano and the inclusion of patches from the powerful Pigments synthesizer. However, the organs and acoustic pianos, while serviceable, may not satisfy purists who might find a better fit with a brand like Nord.

Expanding your sound palette is straightforward, though not without its quirks. You can load additional presets using the AnalogLab desktop software via a USB connection. While wireless transfer through the AstroLab Connect mobile app is an option, its performance is notoriously unreliable. Connecting directly to the keyboard’s own Wi-Fi hotspot offers a more stable experience, though disconnections can still occur.

Managing such a deep sound library is made easier with intelligent organization tools. You can quickly filter presets by category, instrument, or your personal favorites. For live performance, the Songs and Playlists features are incredibly handy, allowing you to group patches and entire setlists for one-button access, making transitions between sounds seamless during a show.

While you cannot build a sound from the ground up, you do have a degree of real-time control. Each preset offers four macro knobs on the left, whose functions change per patch, and four dedicated effect knobs on the right for adjusting reverb, delay, and chorus. This level of control is typical for stage pianos, though the AstroLab feels particularly sparse given the sophistication of the sound engines running underneath. For serious sound design, you would need to upgrade to the full V Collection software to create and then upload your own custom presets.

Sonically, the AstroLab 37 is identical to its bigger siblings; all compromises are in the physical hardware. The faceplate is plastic but feels robust, and it retains the attractive wooden side panels. However, it swaps the large, color-screen navigation wheel of the larger models for a smaller, separate encoder and screen. It also lacks a locking power connector, which could be a concern for energetic performers.

The most significant trade-off is the keyboard itself. The 61-key model features a semi-weighted keybed, and the 88-key version boasts a luxurious, piano-like hammer-action keyboard. The AstroLab 37, by contrast, uses a synth-action keyboard with slim keys and aftertouch. It’s responsive and likely the same mechanism found in Arturia’s KeyStep controllers, but it doesn’t provide the premium, weighted feel of the more expensive models.

Some features, like keyboard splits, feel less practical on a 37-key instrument, and most professional players will likely prefer a larger keyboard for expressive playing. However, for the musician who needs to maximize their sonic options while minimizing the gear they carry, and who wants the reliability of a standalone instrument, the Arturia AstroLab 37 presents a compelling and powerful solution.
