Powered by two alkaline aaa batteries, the compact monotron can be held in one hand. although small enough to easily carry with you, the amazing monotron is packed with korg's legendary analog technology, generating thick and powerful sounds. concentrating on the most important sound parameters, the controls have been streamlined as much as possible. the panel contains only five knobs and one switch. with this level of simplicity, now anyone can easily enjoy the world of analog synthesizers. borrowing the enjoyment of performing with a simple touch from korg's wildly popular kaoss products, the monotron's ribbon controller keyboard takes this ease of use even farther. simple finger gestures can produce expressive effects such as vibrato and glide. the monotron's circuit is radically simple: one voltage-controlled oscillator, one voltage-controlled filter, and one low frequency oscillator. since each knob directly applies a specific change to the sound, the process of sound creation is intuitive, and instantly understandable. the monotron encourages exploration and experimentation, and provides the joy of sonic creativity that's at the heart of analog synthesis. the monotron uses the same highly acclaimed vcf circuit as korg's classic ms-10 and ms-20 semi modular synthesizers. originally released over 30 years ago, these instruments are still coveted today for their aggressive, dynamic filters. the vcf cutoff knob sets the frequency or tone of the filter; the vcf peak knob adds emphasis. a powerful filter is an essential aspect of any analog synthesizer, applying dramatic tonal changes to the sound, and projecting an intense personality that will stand out in any live performance.
