The Korg Monotron Duo is a battery powered, palm sized analog synth. This fun and easy to use synthesizer has a ribbon controller and simple 5 knob, 1 switch operation. Plus, its two oscillators deliver an aggressive, extreme sound that will stand out in any live performance.
Dual Oscillator
The Korg Monotron Duo has two oscillators delivering a more extreme sound. Tune them in unison for a rich, thick analog tone or in intervals for classic solo sounds and generating new effects. The X-MOD (cross modulation) circuit can introduce a mild or razor-sharp edge to the overall sound; everything from a rich vibrato to extreme metallic sounds reminiscent of an FM synth.
Ribbon Controller
The Duo had a ribbon controller keyboard that features a Scale function which selects 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 by simply sliding your finger around on the keyboard.
Korg Filtering
The distinctive tone of an analog filter (VCF) can dramatically alter and enrich the sound. The monotron DUO uses the same highly acclaimed 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; 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 Duo's compact body allow 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
A miniature speaker is built into the monotron Duo. Along with the battery operation and compact size, this feature allows you to enjoy the monotron'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.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
