KORG MICROKORG S MK-1S is a version of the classic microKORG with a built-in 2+1 speaker system, built for a musician who wants to play a full analog synth-and-vocoder set somewhere with no PA power and no amp outlet. Same sound engine as the original, ready to play the moment it's switched on.
Speakers that play louder than their size suggests
A new cabinet design with a bass reflex port and carefully tuned box volume lets the stereo speaker pair and extra woofer put out surprisingly strong low end and clear stereo placement despite the small unit size.The same vocoder, new freedom to play it anywhere
The 8-channel vocoder with Formant Shift works exactly like the classic model, but with no external amp required you can test a vocal idea anywhere — from a band rehearsal to an acoustic outdoor set.KEY FEATURES
