Korg At2 Top

Teaching 30 kids to tune violins is a nightmare. Placing one Korg AT2 Top on the teacher’s desk with the large display allows the whole class to see the needle. The "Sound Out" feature (built-in speaker) plays a reference tone (E-A-D-G-B-E) so students can tune by ear.

At first glance, the Korg AT-2 Top looks like a minimalist, flat control panel with a small display. But for accordionists, it’s a powerful bridge between traditional bellows technique and modern digital synthesis. Designed to mount directly onto the treble (right-hand) side of an accordion, the AT-2 Top is essentially a dedicated sound module controller that pairs with Korg’s acclaimed “Piano” sound engine.

What It Is & How It Works

The AT-2 Top is not a standalone synthesizer. It’s a wireless MIDI controller designed specifically to work with Korg’s AT-2 (Arranger) sound module (or compatible Korg devices like the Pa series arranger keyboards). When connected, the AT-2 Top gives the accordionist real-time control over:

The magic lies in its pressure sensor: the AT-2 Top responds to bellows pressure, translating the natural dynamics of the accordion into expressive volume swells and articulation on the electronic sounds.

Key Features (Physical & Technical)

Why It’s Special (The “Top” Factor)

Availability & Collectibility

The Korg AT-2 system (module + AT-2 Top) was produced from the late 2000s to the mid-2010s. It is no longer in production, making the AT-2 Top a rare and collectible piece. Units in good condition with the original wireless module often sell for high prices on used markets (€400–€700 for the pair, sometimes more for a mint “Top” alone).

Potential Drawbacks

Verdict

The Korg AT-2 Top is a brilliant, niche product that solved a real problem for performing accordionists: adding rich, dynamic electronic timbres without sacrificing acoustic feel or adding stage clutter. It’s a testament to Korg’s willingness to serve non-keyboard musicians. Today, it’s a coveted vintage accessory – not for the casual player, but for the accordionist who demands the best of both acoustic and electronic worlds.

If you find one with its original module, and it fits your instrument, grab it. There’s nothing else quite like it.

Korg AT2 Top (often referred to in parts catalogs as the Korg 504040003001 ) is a specific replacement top-shell component for the Korg microKEY-37 microKEY2-37 MIDI keyboard series. Key Specifications & Use Compatibility

: Designed specifically for the 37-key models of the microKEY series. It is not interchangeable with the 25, 49, or 61-key versions due to the specific width and chassis molding.

: Constructed from a durable, high-impact matte black plastic consistent with Korg’s standard workstation and synthesizer Replacement Purpose

: Typically used for repairing units with structural damage to the upper casing, such as cracks near the keybed or damage around the side-mounted pitch and modulation wheels. Maintenance & Installation Part Sourcing

: Authentic replacement shells are usually sourced through authorized Korg service centers or specialized instrument parts retailers. Installation

: Replacing the top requires a complete teardown of the keyboard. This involves removing all bottom screws, disconnecting the internal ribbon cables between the mainboard and the keybed, and carefully unseating the pitch/mod wheels from their brackets.

: Because the microKEY is a USB-powered device with sensitive internal circuitry, it is recommended to use an anti-static wrist strap during the transfer of components to the new shell to prevent electrostatic discharge (ESD) repair guide for the microKEY?
