Korg puts the thrill of the analog synthesizer into everyone’s hands. Announcing the new monotron DELAY.

Go Anywhere Analog: That was the theme behind the remarkable battery-powered and palm-sized analog synthesizer that Korg dubbed the monotron. Now the powerful and fun-to-play monotron is joined by two new siblings. The Dual Oscillator monotron DUO offers X-MOD capabilities for generating even more extreme sounds. The monotron DELAY features a Space Delay that can produce intense, analog-like echo effects. Each is played from a ribbon controller keyboard with newly added features. The monotron’s simple operation and ease of use (5 knobs and 1 switch) is alive and well, inviting hours of enjoyment and musical exploration.

Casual users and gadget mavens will quickly enjoy performing melodies, DJs can create dazzling effects on stage, while established players can add analog muscle to their performance – the possibilities are virtually unlimited. Grab yourself a monotron, monotron DUO, or monotron DELAY, and get in touch with the exciting world of analog synths.

Classic Analog Synth / Space Delay Combination

A good delay was an essential part of the classic analog synthesizer sound. More often than not, that delay came from a tape-style echo machine until affordable digital delays were created. The monotron DELAY is an analog synthesizer optimized for sound effects. In addition to its analog oscillator, filter, and LFO, it also provides a Space Delay that's indispensible for swooping, cosmic sounds. The monotron DELAY even reproduces the pitch changes that occur when you vary the delay time, just as though you were using an analog tape echo. This fat and warm delay will add an authentic edge to your analog sounds!

Dual-Waveform LFO

The Low Frequency Oscillator (LFO) waveform used to modulate the pitch now offers a choice of waveshapes – a new square wave plus the traditional triangle wave. Both the Rate (Speed) and the Intensity (Depth) can be adjusted independently. In addition, a trimpot on the back panel can continuously adjust the shape/direction of the triangle wave or the pulse-width of the square wave to deliver even more versatility. Used in conjunction with the delay, the LFO can create dazzling effects and provide unique possibilities for embellishing your songs.

Wide-Range Ribbon Keyboard

The monotron DELAY's ribbon controller keyboard features a wide, four-octave range. This design allows the pitch to be controlled even more aggressively and dynamically, making the monotron DELAY a great weapon for a DJ to get the floor moving with irresistible sound. The reversed white keys and body adornments glows under black light illumination, making the monotron DELAY ideal for delivering a striking visual impact in nearly any club environment.

Classic Korg Filtering

The distinctive tone of an analog filter (VCF) can dramatically alter and enrich the sound. The monotron DELAY 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.

Fully-patchable Filter

The input jack (AUX input) built into the monotron DELAY’s compact body allow you to place any audio source into the monotron DELAY’s signal path, directly before the analog filter and delay circuit. This provides a great way to connect a KAOSSILATOR, a guitar, or a digital audio player to the monotron and enjoy tone-bending filter and delay effect.

Go Anywhere Analog

A miniature speaker is built into the monotron DELAY. Along with the battery operation and compact size, this feature allows you to enjoy the share the monotron DELAY’s analog synthesis sound with your friends, anywhere, at any time. There's also a headphone output that you can use when practicing in private, creating sounds at home, recording, or for connecting to an amplifier or PA system.
