Korg EXs325 Yangqin: Tradition Meets Digital Articulation

The heart of the EXs325 library lies in its articulation palette, which Korg showcases with methodical clarity. Users can access a variety of attack and stick variations—main, reverse, bottom, and finger techniques—each imparting a distinct character to the sound. The video demonstrates how different hammers and striking points yield sharper or softer timbres, and even finger plucking is represented for a gentler, more intimate tone.

Tremolo, a signature Yangqin articulation, receives special attention. Korg’s programming allows for both manual and tempo-synced tremolo, with joystick assignments (notably the +Y axis) offering real-time control over articulation dynamics. Harmonics are also included, providing shimmering overtones that expand the instrument’s expressive range. The ghost note feature is particularly notable: by simulating the rapid, bouncing hammer technique, the EXs325 enables nuanced rhythmic textures that go beyond simple note repetition.

This breadth of articulations isn’t just about sonic variety—it’s about enabling authentic performance workflows. The video makes it clear that these techniques are mapped for intuitive access, allowing players to move seamlessly between expressive gestures without menu-diving or cumbersome key-switching.

Korg leverages advanced PCM editing and sound programming to bridge the gap between static samples and organic performance. The use of vector crossfading is highlighted as a key technique, allowing for stepless dynamic transitions that mimic the real Yangqin’s continuous expression. This means that musicians can perform crescendos, diminuendos, and subtle timbral shifts with a realism that’s often elusive in sample-based instruments.

Performance control isn’t limited to velocity alone. The EXs325 programs respond to a range of controllers—joystick, ribbon, and switches—enabling nuanced manipulation of articulations and dynamics. This flexibility is crucial for integrating the Yangqin into both studio and live workflows, giving performers the tools to shape phrases in real time rather than relying on post-production tweaks.

To further enhance authenticity, Korg implements round robin sampling—a technique that cycles through multiple sample variations for repeated notes, reducing the mechanical feel of digital repetition. The video points out that both regular and round robin versions are provided, giving users the choice between absolute purity and a more natural, performance-like response. This dual approach acknowledges the subtle trade-offs inherent in digital emulation.

Tempo-adaptive tremolo, powered by wave sequencing, is another standout feature. By syncing tremolo speed to MIDI tempo or time code, the EXs325 ensures that rhythmic articulations stay locked to the musical context—vital for modern productions and live setups. Together, these features push the EXs325 beyond static sampling, offering a level of realism and flexibility that invites creative exploration while respecting the instrument’s traditional roots.
