Wooden body with a beautifully lustrous finish in your choice of three colorsThe attraction of the RK lies in its beautiful body. The carefully made wooden body consciously reflects the design of a guitar, projecting a timeless coolness that creates varying impressions depending on your angle of view, and featuring a new and elegantly curvaceous design.Two hundred built-in programs powered by analog modelingThe RK-100S provides a built-in sound engine that was not found on the original RK, meaning that you can perform simply by connecting an audio cable.Its MMT sound engine provides not only the standard analog synthesizer waveforms such as sawtooth and square, but also additional oscillator algorithms such as formant waveforms, noise, and PCM, which power two hundred programs for a broad range of sounds that will cover any musical genre. These sounds can also be played using the arpeggiator.37-note slim keyboard that’s lightweight and easy to playThe keyboard of the RK-100S uses the 37-note slim keyboard also featured on the MS-20 mini. This allows the overall unit to be more compact and lightweight. MS-20 mini-style keys provide the perfect balance between size and playability.Two ribbon controllers, short and longSince the RK-100S is designed for active playing styles, it features two ribbon controllers: a short ribbon on the neck that can be manipulated with the left hand, and a long ribbon located in front of the keyboard that gives you a wide range of performance possibilities. The long ribbon controller can be used instead of the keyboard to play a freely specified range of pitches and scales, and can also be used to control the pitch or filter in dramatic ways.Operates on six AA alkaline batteriesSince the RK-100S will operate on easily obtainable alkaline AA batteries or rechargeable nickel-metal hydride AA batteries, you can enjoy performing anywhere simply by plugging in a set of headphones or by connecting it to your amp with a standard cable. By using an AC adapter, you can play at home for as long as you like without being concerned with battery life, and use the PC editor to create your own sounds.Mic/audio (dual-purpose) input jack, also usable with the vocoder functionThe RK-100S provides a monaural mini-input jack that can also work with mic input. You can use a headset mic to enjoy vocoder performance, or connect your audio player and perform along with your favorite music.Perform with an external sound module, and use the PC editor for detailed editingSince the RK-100S is equipped with a MIDI output jack, it can be used to control an external sound module. There’s also a USB port for connecting it to your computer, allowing you to control a PC sound module or use the PC editor to edit detailed MIDI settings and parameters of the internal sound engine.*You can change the PC editor’s background color to match your RK’s body color: Red, Black or White.Windows System Requirements:
