The Korg KRONOS 73 is a professional-grade music workstation that is a core part of Korg’s flagship synthesizer line. It shares all the powerful features of its 61-key and 88-key siblings, with a key difference being the keyboard action, which makes it a preferred choice for many gigging keyboardists and studio musicians.
Key Features and Highlights:
- Premium Keyboard Action: The KRONOS 73-key model features Korg’s RH3 (Real Weighted Hammer Action 3) keyboard. This is a crucial distinction from the 61-key version’s semi-weighted keys. The RH3 action is a graded hammer action, meaning the keys are heavier in the low registers and get progressively lighter as you move up the keyboard, just like on a grand piano. This provides a truly authentic piano feel, making it an excellent choice for pianists who need the flexibility of a workstation. The keys are also velocity-sensitive and support aftertouch, allowing for incredibly expressive performances.
- Nine Distinct Sound Engines: Like all KRONOS models, the 73-key version is a powerhouse with nine different synthesis engines. These engines, which can be used simultaneously in a single performance, include:
- SGX-2 Premium Piano: A highly detailed acoustic piano engine with non-looping samples and physical modeling of string resonance and mechanical noise.
- EP-1 Electric Piano: A physical modeling engine that recreates classic electric pianos with incredible realism.
- CX-3 Tonewheel Organ: An organ engine with realistic drawbars and rotary speaker effects.
- HD-1 High Definition Synthesizer: A powerful sample-based synth.
- AL-1 Analog Synthesizer: A virtual analog engine.
- MS-20EX & PolysixEX: Component modeling of Korg’s classic monosynth and polysynth.
- MOD-7 Waveshaping VPM Synthesizer: An advanced FM synth.
- STR-1 Plucked String Synthesizer: A physical modeling synth for realistic string sounds.
- TouchView™ Display: The KRONOS 73 features the same large, 8-inch color TouchView™ display. This screen is the central hub for navigating the deep functionality of the workstation, making it easy to edit sounds, arrange music, and manage your workflow.
- Comprehensive Sequencer and Recorder: It’s a true music production center with a 16-track MIDI sequencer and a 16-track audio recorder. This allows you to record both MIDI data and audio from external sources like microphones and instruments.
- Open Sampling System: You can sample audio directly from any source and integrate it into your music. The generous internal SSD (Solid-State Drive) provides extremely fast loading times for the vast sound libraries and any user-created samples.
- KARMA & Drum Track: It includes Korg’s KARMA algorithmic music technology, which generates complex musical phrases in real time. The “Drum Track” feature provides professional drum grooves for practice or to lay the foundation for a new song.
- Extensive Effects Suite: The KRONOS offers a powerful effects section with 12 insert effects, two master effects, and two total effects, providing a wide range of sonic manipulation capabilities.
