Korg RK-100S 2RD 37-key Red Keytar Synthesizer

The Korg RK-100S 2 Keytar in translucent red is built for musicians who refuse to be anchored behind a keyboard stand. With 37 velocity-sensitive keys and Korg's MMT (Multiple Modeling Technology) sound engine driving 200 presets, it delivers a broad sonic range — from aggressive lead synths to lush pads — all in a portable, strap-on form factor. The dual ribbon controllers are a standout feature, giving performers intuitive, real-time control over pitch, modulation, and filter parameters without interrupting their stage movement. The wooden body adds warmth to its aesthetic and a reassuring solidity in hand.

Beyond its role as a standalone instrument, the RK-100S 2 connects via USB and traditional MIDI, making it a capable controller for DAW-based production and external hardware synths. The included gig bag makes gigging convenient, and the striking red finish ensures it commands attention under stage lights. While the 8-note polyphony and 37-key range mean this is best suited for lead lines, solos, and melodic hooks rather than complex harmonic layering, that is precisely the role a keytar is designed to fill — and the RK-100S 2 fills it with style and substance.
