电磁持续罗兹钢琴是一个原始的罗兹钢琴修改，以提供控制个别音符的振幅信封通过aftertouch压力。虽然有许多机会在扬声器放大之前对幅度包络进行整形，但它们都由音调产生机构的不断衰减的物理振动控制。在NIME 2011上，提出了对这种振动机制进行电磁控制的单音符概念验证。在过去一年中，该系统的几乎每一个方面都得到了改进。我们使用不同的振动传感器，不受电磁干扰，从而消除了麻烦的反馈。在控制方面，我们既降低了成本，又在整个按键运动范围内获得了连续的位置感测，此外还有触后压力。最后，整个系统现在适合原始钢琴的空间限制，允许它安装在相邻的音符上。
The Electromagnetically Sustained Rhodes Piano is an original Rhodes Piano modified to provide control over the amplitude envelope of individual notes through aftertouch pressure. Although there are many opportunities to shape the amplitude envelope before loudspeaker amplification, they are all governed by the ever-decaying physical vibrations of the tone generating mechanism. A single-note proof of concept for electromagnetic control over this vibrating mechanism was presented at NIME 2011. In the past year, virtually every aspect of the system has been improved. We use a different vibration sensor that is immune to electromagnetic interference, thus eliminating troublesome feedback. For control, we both reduce cost and gain continuous position sensing throughout the entire range of key motion in addition to aftertouch pressure. Finally, the entire system now fits within the space constraints presented by the original piano, allowing it to be installed on adjacent notes.
