This renewal application is based on the ongoing DFG Project Real-time FPGA Implementation of Musical Instruments using Physical Modeling an now focusses on applying the fully working real-time implementation of differential equations for sound production of musical instruemtns on an FPGA hardware to instrument builders and workshops. Based on the successful patent of the system and the seek for industry utilization, one of the worlds largest instrument builders, Steinway & Sons, was enthusiastic to include the method in their process of instrument improvement. Here a complete piano is to be simulated in real-time so that all geometrical and material parameters needed by the instrument builder can also be varied in real-time. Therefore, in close cooperation with the development division of Steinway & Sons, a software is developed which makes it easily possible for a user to change these parameters, and which is then used in the daily process of piano improvement and modification. Therefore, Steinway builts two test pianos and modifies them constantly according to results of measurements made by a microphone-array recordings of the piano radiation, as well as high-speed camera video recordings of the piano strings.

该更新申请基于正在进行的DFG项目“使用物理建模的乐器实时FPGA实现”，现在专注于在FPGA硬件上应用完全工作的实时实现微分方程，用于乐器制造商和研讨会。基于该系统的成功专利和寻求工业应用，世界上最大的仪器制造商之一，施坦威父子公司，热衷于将该方法纳入他们的仪器改进过程。在这里，一台完整的钢琴将被实时模拟，因此乐器制造商所需的所有几何和材料参数也可以实时变化。因此，在与施坦威开发部门的密切合作下，开发了一个软件，使用户可以轻松地更改这些参数，然后在钢琴改进和修改的日常过程中使用。因此，施坦威制造了两架测试钢琴，并根据钢琴辐射的麦克风阵列记录以及钢琴琴弦的高速摄像机视频记录的测量结果不断对其进行修改。
