GuiaRT is an interactive musical setup based on a nylon-string guitar equipped with hexaphonic piezoelectric pickups. It consists of a modular set of real-time tools for the symbolic transcription, variation, and triggering of selected segments during a performance, as well as some audio processing capabilities. Its development relied on an iterative approach, with distinct phases dedicated to feature extraction, transcriptions, and creative use. This article covers the motivations for this augmented instrument and several details of its implementation, including the hardware and strategies for identifying the most typical types of sound produced on a nylon-string guitar, as well as tools for symbolic musical transformations. This acoustic–digital interface was primarily designed for interactive exploration, and it has also been effectively used in performance analyses and as a pedagogical tool.

GuiaRT 是一种交互式音乐设置，基于配备六音压电拾音器的尼龙弦吉他。它由一组模块化的实时工具组成，用于在表演期间对选定片段进行符号转录、变化和触发，以及一些音频处理功能。它的开发依赖于迭代方法，具有专门用于特征提取、转录和创造性使用的不同阶段。本文介绍了这种增强乐器的动机及其实现的几个细节，包括用于识别尼龙弦吉他产生的最典型声音类型的硬件和策略，以及用于符号音乐转换的工具。这种声学数字接口主要是为交互式探索而设计的，
