Electronic Sensitivity 电敏感
This method has a lot to do with circuit instability, touch and feedback. by touching selected nodes from circuit, new connections are made, circuits behaviors are also affected. Its main difference from fine sensing technology is : With sensors gestures are turned into values then mapped to sound parameters. But with electronic sensitivity it's circuit that's manipulated. A single change can result in a complex combination of sound parameters. It's naturally a more experimental method and results are unknown until tried, maybe boring or extraordinary and full of expressive potentials.
synth pioneer Peter B created the sandrode concept - androgynous nodes that are neither input nor output, but perform both functions at different times. They are actually selected raw nodes from circuits, each time they are touched / patched, it effectively create a new circuit, and most of the time it would affect many aspects of sound. At the same time as sandrodes are unprotected, raw nodes, it's highly possible to destroy components by combining units. I look forward that more self-contained units using this method would be available to the public.
这种演奏途径和电路的不稳定性，触控还有回授有很大关系。通过触摸电路中的一些节点，新的电路会形成，电路的反应也会受到影响。电敏感和传统的精细传感乐器（例如 Continuum, Seaboard 等等）的区别在于：精细传感乐器会把演奏者的操作转换为数值，继而使用这些数值去控制声音合成的参数；而电敏感的手段是通过直接影响电路来完成的，所获得的声音改变可能是复杂多变的，在尝试之前并不可知。所以后者也是更为实验的一种方法。结果也许不尽人意，但是也可能是非常好听而富有表现力的。
合成器大师 Peter B 曾经创造了 "sandrode" 这个概念。它指的是又能作为输出，也能作为输入的电路端点。从根本上来说，它们其实就是一些未经保护和匹配的电路节点。通过对它们的操作，我们一定程度上是在组装新的电路，这通常也能导致在声音上很多属性的同时变化。与此同时，未保护的电路节点在几台机器相互连接的同时很可能损坏元件，所以一般来讲这种玩法都会被限制在同一台乐器上。我期待有更多使用这种玩法的乐器出现。
this combination of 5-rolz circuits and a sidrax emerged from my former experimentation with sidrolz and tetrolz instruments. that if a sandrode is patched to a piezo input via a resistor and a capacitor, it can stay silent until a sandrode is touched.
the 5-rolz circuits are actually “wrong” in traditional sense and very easily interfered and falling into various semi-stable states. there are so many hidden sweet spots and accidents to discover but at the same time most patches and playing gestures are fairly reproducible making it a learnable instrument. hi
all sandrodes are available on the panel so they can be used to modulate pitch and timber. also they are normalled to control the stereo VCA for each voice. This setup enables complex parallel voices relationships far more than simple mixing.
