A few years ago I joined a local band as keyboard player, and it was there I was introduced to the microKorg. Despite the rather amateurish looking premise of categorizing sounds with a 'genre selection knob' and the baby-sized keys, I found myself constantly inspired while jamming with it, and the sounds it could make when connected to a PA rig were massive in contrast to the microKorg's tiny size.
A couple of months ago I decided I must own one, and ended up with the newer microKorg XL because it was on offer for very little more. In comparison to the classic model, the XL has 8 voices - double the polyphony, a 16-band vocoder (the original was an 8 band - and surprisingly intelligible for it), and a seemingly identical but expanded synth engine. After ordering, however, I found out that despite the similarities in features, the XL's engine is based off of Korg's Radias 'Multi Modelling Technology' (whatever that is), while the original is not.
