Ample China Qudi (ACQD) is an advanced virtual instrument built on the latest woodwind sampling technology, featuring 4.4 GB of meticulously recorded samples. It captures the elegant sound of the D key Qudi, handcrafted by Jianhong Wang, and performed by Xiaokui Ding, a distinguished woodwind artist. The library includes various articulations such as head and body articulations, special effects, and a curated set of improvised licks, offering rich expressive possibilities. The samples are recorded with five microphones, allowing users to mix and shape the sound with adjustable mic volumes and EQ settings, and two mic modes designed for both modern and traditional tonal colors.

The instrument delivers excellent dynamic range and timbral variation through multiple velocity layers and detailed articulation controls, including grace notes, legatos, vibratos, and trills. A sophisticated legato system intelligently adapts to note duration and velocity to produce natural transitions and expressive performance nuances. Unique features such as endless articulation legatos and a creative mirroring function enable users to reverse and modify articulations in real time, enhancing musical expression. Additionally, the SAHDS modulation system provides independent vibrato and modulation envelopes per note, allowing for realistic and dynamic phrasing. The controllable wind effect adds an authentic breathiness to the sound, which can be adjusted to suit performance needs.

ACQD also includes a powerful set of built-in effects to polish and refine the sound, featuring an 8-band EQ with real-time spectrum visualization, a versatile compressor with multiple detection modes, a 6-tap echo with individual parameter controls, and an IR reverb offering various acoustic environments such as room, studio, and hall settings. These tools enable users to craft a professional and immersive soundscape directly within the instrument. With its deep sampling, intelligent performance features, and comprehensive effects, Ample China Qudi stands out as a premium choice for composers and musicians seeking authentic traditional Chinese woodwind sounds.
