Innovation and tradition are two fundamental factors in the design of new digital musical instruments. Although apparently mutually exclusive, novelty does not imply a total disconnection from what we have inherited from hundreds of years of traditional design, and the balance of these two factors often determines the overall quality of an instrument. Inspired by this rationale, in this article we introduce the Hyper Drumhead, a novel augmented virtual instrument whose design is deeply rooted in traditional musical paradigms, yet aimed at the exploration of unprecedented sounds and control. In the first part of the article we analyze the concepts of designing an augmented virtual instrument, explaining their connection with the practice of augmenting traditional instruments. Then we describe the design of the Hyper Drumhead in detail, focusing on its innovative physical modeling implementation. The finite-difference time-domain solver that we use runs on the parallel cores of a commercially available graphics card and permits the simulation of real-time 2-D wave propagation in massively sized domains. Thanks to the modularity of this implementation, musicians can create several 2-D virtual percussive instruments that support realistic playing techniques but whose affordances can be enhanced beyond most of the limits of traditional augmentation.

增强型虚拟打击乐器上的扩展演奏技巧

创新和传统是设计新数字乐器的两个基本因素。虽然表面上相互排斥，但新颖并不意味着与我们从数百年的传统设计中继承的东西完全脱节，这两个因素的平衡往往决定了乐器的整体质量。受此基本原理的启发，在本文中，我们介绍了 Hyper Drumhead，这是一种新颖的增强虚拟乐器，其设计深深植根于传统音乐范式，但旨在探索前所未有的声音和控制。在文章的第一部分，我们分析了设计增强虚拟仪器的概念，解释了它们与增强传统仪器实践的联系。然后我们详细描述了 Hyper Drumhead 的设计，专注于其创新的物理建模实现。我们使用的有限差分时域求解器在商用显卡的并行核心上运行，并允许在大规模域中模拟实时二维波传播。由于此实现的模块化，音乐家可以创建多种 2-D 虚拟打击乐器，这些乐器支持逼真的演奏技巧，但其可供性可以增强，超出传统增强的大多数限制。
