Korg Monotron Duo Analog Ribbon Synthesizer
- Dual Oscillator: The Monotron Duo features two oscillators that can be tuned in unison or intervals to generate a rich, thick analog tone. The X-MOD circuit adds a sharp edge to the overall sound, ranging from a rich vibrato to metallic sounds reminiscent of an FM synth.
- Ribbon Controller: The ribbon controller keyboard features four scales – Chromatic, Major, Minor, or Off – to generate precise pitches or musically coherent phrases by sliding your finger around the keyboard.
- Korg Filtering: The Monotron Duo uses the same VCF circuit as Korg’s classic MS-10 and MS-20 semi-modular synthesizers. The VCF Cutoff knob sets the frequency or tone of the filter, while the VCF Peak knob adds emphasis, providing a powerful filter that dramatically alters and enriches the sound.
- Fully Patchable Filter: The input jack (AUX input) allows you to place any audio source into the signal path, directly before the analog filter. This provides a great way to connect a Kaossilator, a guitar, or a digital audio player to the Monotron and enjoy tone-bending filter effects.
- Compact and Portable: The Monotron Duo is a battery-powered, palm-sized analog synth with a miniature speaker built-in, allowing you to enjoy its analog synthesis sound anywhere, anytime. It also features a headphone output for private use and is lightweight, weighing only 95g without batteries.
