MIDI to Control Voltage
​
MIDI to control voltage describes a method to interface digital control of analog music synthesis.
​
An analog modular synthesizer is an electronic system that synthesizes sound using a network of control points that can respond to a range of various analog voltages. Simple or very complex electronic modules can be linked together with patch cables in combinations only limited by physical space to create completely unique sounds.
​
MIDI stands for musical instrument digital interface and is a hardware and communications standard used to interface both musical instruments and musical software. MIDI data is not an audio format, but it is a description of musical events. For instance, every key on a keyboard has a value assigned to it by the MIDI standard and playing a series of keys will produce data about which keys were played, at what velocity, order, duration, and so on. This data can be stored and edited for later playback, or it can be fed directly into any device that can understand the MIDI standard.

Adding MIDI control to an analog synthesizer adds another level to the ability to explore and experiment in musical synthesis, increasing the exponent of the musical equation.
