KORG KRONOS 3 73 - Professional 73-key RH3 workstation with 9 engines, set list, and 16+16 sequencer

The KORG KRONOS 3 73 puts the KRONOS series back in the spotlight with 60% faster boot-up , a new all-black finish, and a major sonic upgrade featuring 256 additional programs (128 brand new + 128 curated from KSL libraries). Its Japanese-made RH3 keyboard—with graded response and aftertouch —delivers piano-like feel in a performance-oriented 73-key format. The architecture retains the 9 synthesis engines (SGX-2, EP-1, HD-1, AL-1, CX-3, STR-1, MOD-7, MS-20EX, and PolysixEX), 8" TouchView display, and Set List mode with SST for seamless transitions—all powered by a 120GB internal SSD and a curated selection of thousands of presets.

With approximately 3 GB of PCM RAM , over 21 GB of internal waveforms, and access to 300+ KRONOS libraries , the sonic palette is virtually inexhaustible. In terms of connectivity, the KRONOS 3 integrates a 24-bit/48 kHz (2x2) USB audio interface , MAIN and four individual outputs , optical SPDIF , balanced audio inputs with MIC/LINE switching, and USB-A ports for controllers/storage. The control panel offers nine faders , eight potentiometers , a joystick , a vector joystick , a ribbon , and assignable footswitches for direct stage control.
