Got the Prologue 12 - Korg just has that sound about them that is unique and totally worth the extra $$ for the additional voices, and the few extras that come with like the LF compressor, extra keys, oscilloscope, access to menu items, and onboard effects. You have to keep in mind that this synth is analog with presets, with updated synth technology. Playing with the presets and storage areas can be used as a starting point in the creative process - creating pretty incredible new sounds to store. The extra Digital oscillator engine is an added plus that is yet to be utilized. There are features that should have been added - like a sequencer, and after touch - which are the biggest complaints at this price. If the Mini versions have it - doesn't make sense not including on the flagship. It is was it is - other options out there.
