As reported by engadget,
Of course, this isn’t a 100-percent faithful recreation of the ‘70s modular synth. Korg expanded the feature set to make it work better in a modern music-making environment. For one, all of the control voltages have been normalized to five volts instead of 10, making it easier to integrate with other modular gear and Eurorack equipment. It also has USB host capabilities so, while it doesn’t come with a separate keyboard module, you can connect any USB MIDI controller you want and get straight to playing. Korg also ditched the original XLR audio outs and went with TS style jacks.
Unfortunately there’s no word on when the 2600 M will ship or how much it will cost. But hopefully the price is on a similar diet plan as the rest of the synth, because the $3,900 the recent reissue commanded was definitely too much for all but the most dedicated synth nerds.
