  • Product Description

    Dual Oscillator Analog Pocket Synth - Korg's dual-oscillator Monotron DUO fits in your pocket, yet delivers enormous analog sound! Equipped with a built-in speaker and battery operation, Monotron DUO is ready - anytime, anyplace. Best of all, it's a blast to play, with a level of simplicity allowing anyone to enjoy the world of analog synthesizers. Product Block Copy Offering two oscillators, the monotron DUO adds an extra dimension of sound. Tune the oscillators in unison for a rich, thick, analog tone; in intervals for classic soloing sounds and generating new effects. The X-MOD (cross modulation) circuit taken from Korg's classic Mono/Poly can introduce a mild or razor-sharp edge to the overall sound. The monotron DUO's ribbon controller keyboard features a Scale function to select one of four scales: Chromatic, Major, Minor, or Off. Choose the Chromatic scale to play precise pitches as on a piano, or choose Major or Minor to generate musically coherent phrases on the keyboard.

    Customers like the quality of the musical instruments. They say it's an amazing little synth, with many cool sounds and effects. It's a great choice for electronic music lovers, and produces beautifully rich harmonic overtones.

    Customers find the noise of the musical instruments to be really fun, addicting, and a blast to mess around with. They also say it's an excellent toy and surprisingly fun instrument.

    Customers like the performance of the musical instruments. They mention that it works great for their purpose, gets great results, and works well with mixers. Some say that it comes with batteries and works right out of the box. Customers also say that the device is rock-solid and totally delivers. They also mention that the add of effect works well and is an extremely powerful tool.

    "I bought this with the Monotron Delay and they work very well together...." Read more

    "...so knock yourself out- you really can't go wrong- the looper is powerful.. it can overpower the unit, so just remember ,"the last button IS..." Read more

    Customers find the musical instruments easy to use and play. They say it's simple to figure out, and a highly portable live kit.

    Customers like the filter of the musical instruments. They mention that it's awesome, powerful, and versatile. They also appreciate the low-pass, cutoff, and resonant filters. The aux input has a classic MS20 filter, and it can be used as a filter box for external sounds. Some say that the filter on this little box is evil.

    "...is great (featuring both cutoff and peak controls), and the dual use of the LFO (for the pitch and filter cutoff) allows for a wide variety of sounds..." Read more

    "...Second, for the size and features, it's just a great value--the filter is awesome, and the type of sound you can get out of this little thing is..." Read more

    "...The low end is pretty cool to play with...." Read more

    55 customers mention37 positive18 negative

    Customers are mixed about the portability of the musical instruments. Some mention it's extremely portable, light weight, and compact. They say it'll fit in their pocket and is great to use as a small, affordable delay effect to add to an instrument. However, others say that it'd be better suited for a child's pocket. The size of the keys makes it difficult to perform songs, and the length of the scale prevents it from being accurate.

    "...And it's great to use as a small, affordable delay effect to add to an instrument -- especially something like a Volca or something similar where..." Read more

    "...I found it, and my first impression was "THIS IS small!". It fits in the palm of my hand. Yeah, I have big hands, sort of...." Read more

    "...Downside(s): -Like I said, it is kind of small, and I am worried that its plastic body may eventually break, but I suppose that just..." Read more

    "...with you and show that person what it can do, since it can easily fit in your pocket." Read more

    Neat little gadget
    4 Stars
    Neat little gadget
    Pretty cool little gadget, however my 6 year old daughter wasn't impressed at all. So I wouldn't advise buying for younger kids, I wouldn't buy for anyone that didn't show a clear interest in sound design. That being said, I bought this for myself just cause something about it fascinated me. Perhaps the size or portability drew me in. But after many month with this device I can say don't expect this to be a compositional tool for building songs. It's more of a novelty item I suppose. While it can produce some neat & trippy sounds, then only actual practical use for this gadget in terms of production is hooking it up in an effects chain on some other sound generator.Even though this costs much less than the korg volcas, I still can't help but feel like it's still a bit over-priced since basically everything it can do is limited in one way or another. I can't imagine this thing costing more than $3 or $4 to manufacture per unit. For a ~$50 price point it really should come with a few extra features, or actually be playable in an arrangement. If nothing else it should have some type of usb connection for some computer or tablet integration. But since that isn't the case, & this is what we get take it or leave it, I feel strongly that this should retail for about $20, or no more than $30. When I made this purchase I already considered a 75% chance that I would feel this way after buying, so with that in mind & my expectations at a reasonable & logical level towards this gadget I don't feel to bitter about feeling this purchase. I still hope for a day when this thing will be a perfect unexpected answer for part of a jam that I'm working on one day, but until that day it's rather cemented as a neat novelty.Hope this helps someone else out there.
