Korg TRITON-RACK is a 2-space rackmount sound module version of the famous TRITON music workstation, delivering the same Hyper Integrated (HI) synthesis and sampling engine without the built-in keyboard. [1, 2, 3, 4]Key Features and Architecture

• Sound Engine & Polyphony: Features a 60-voice polyphonic tone generator packed with rich multi-samples, dual polyphonic arpeggiators, and Realtime Pattern Play Recording (RPPR). [1, 2]
• Massive Expansion: Unlike the keyboard versions, the TRITON-RACK accommodates up to eight EXB-PCM expansion boards, expanding total wave memory to 160 MB and allowing access to over 2,000 programs. [1]
• User Interface: Replaced the keyboard's large touchscreen with a smaller 240x64-dot graphic LCD, cursor navigation, and soft keys. As noted by users on Reddit, editing parameters on the rack model is a bit more challenging due to the button-based navigation instead of a touchscreen editor. [1, 2]
• Connectivity & Storage: Includes built-in S/PDIF digital output, a floppy disk drive (often upgraded by users to a USB floppy emulator), and support for optional digital interface cards like ADAT (EXB-DI) or mLAN
