KORG RK-100S 2 BK - 37-Key MMT Keytar/Synthesizer with 16-Band Vocoder (Translucent Black Finish)

The KORG RK-100S 2 BK reimagines the iconic KORG keytar with a handcrafted, lacquered wood body with a translucent black finish that showcases the grain. Its stage-ready aesthetic features include the MMT (Multiple Modeling Technology) engine with 200 programs , up to 8-voice polyphony (4 in vocoder mode), an arpeggiator , and an effects chain with timbre-specific EQ and 17 master algorithms . Its slim, 37-note keyboard is velocity-sensitive, and two ribbons —a short one on the neck for pitch bend /modulation and a long one next to the keyboard for pitch or filter control and scale play—multiply the expressiveness of solos and sweeps.

For performance and production, the RK-100S 2 adds a 16-band vocoder with a mini jack input ( MIC1/MIC2 or LINE gain switching) and a 6.3 mm stereo/headphone output . A MIDI OUT and USB Type B are provided for data/MIDI and in-depth editing using the RK-100S 2 Sound Editor . It runs on 6 AA batteries (approximately 8 hours of battery life) or an optional 9V adapter , and includes a strap and soft case, so you can hit the stage and perform.
