Monotron Duo : great toy with a big sound!

for the price it is amazing, lots of fun, running external audio thru the filter is a nice bonus. the only negative is the noise, there is a constant loud hiss which is due to the nature of the circuit design. it wont be a problem for everyone but it was for me. its most noticeable when the filter is nearly closed, which makes using the filter as a studio production effect not an option, for me anyway.

if you have the patience you could record samples of each note and use a noise analyzer/reducer on each sample to clean it up. then use a sampler for poly action!

the cross modulation can give some really big and aggresive techno pads when both oscillators are slightly detuned.

this tiny Korg would be a perfect introduction to analog synths, I have owned some classics in the past and sold them all but buying Monotron Duo brought back my love for synths!
