Overview
The Impression of Jiazhou is a 7-minute-46-second real-time interactive work for alto saxophone and live electronics. It grew out of a visit to Leshan, the former Jiazhou, and the contrast between dense forest, city traffic, night streets, the Minjiang River, and the solemnity of the Buddha statue.
Interaction
The PS5 controller's left and right joysticks generate spectral data for a Migrator transformation. An envelope follower tracks the saxophone's dynamics and uses that data to reshape the spectral saturation, so the performer's breath and force become part of the electronic color.
System
The Max/MSP system combines plate reverb, ring modulation, FFT spectral harmonizer, FFT spectral delay, spectral transformation, and a self-built spectral saturator.
概览
《嘉州印象》是一部时长 7 分 46 秒、为中音萨克斯管与现场电子而作的实时交互作品。作品源于作曲家对乐山（古称嘉州）的访问：密林、城市道路、夜灯下的寂静、岷江的流动、佛像的庄严与嘉州人的热情共同构成了它的感知起点。
交互方式
PS5 手柄的左右摇杆实时生成 Migrator 变换所需的频谱数据；包络跟随器追踪萨克斯管的音量动态，并以此重塑频谱饱和。演奏者的呼吸与力度因此成为电子音色的一部分。
系统
Max/MSP 系统结合了板式混响、环形调制、FFT 频谱和声器、FFT 频谱延迟、频谱变换与自建频谱饱和模块。
