Korg Keystage 49
The Keystage 49 is a pro-tier controller notable as the first MIDI 2.0 keyboard with polyphonic aftertouch and per-knob OLED displays, with USB-B and MIDI DIN. It's for producers who want next-gen MIDI expression and detailed hands-on control over parameters. It lacks CV/Gate outs, so skip it for sequencing modular hardware, and its price puts it out of reach for budget rigs.
