#6 observing how various CV source types affect oscillator pitch

Electronic music instruments rely on control voltages in some form or another. Both analog and digital systems require a means of changing pitch, timbre, loudness, and other sonic characteristics. This is achieved using control voltage, or in the case of software like Propellerhead Reason, a digital representation of control voltage.

A powerful feature of Propellerhead Reason is the implementation of signal routing in the virtual rack environment. This system includes both audio cabling and control voltage cabling. A single modulation source, such as an LFO, can control several other synths that react the instant you alter the LFO settings. This ability to have a signal from one software synthesizer control a different software synth, is an amazing feature that often goes overlooked.

For Reason users, interested in learning about control voltage routing, this on-going series will provide an introduction to the terminology and protocols in using this feature in Propellerhead Reason. The tutorials are presented as individual Reason Song Files and require various Rack Extensions that help illustrate active processes. Each lesson is embedded in the session file, so you actively experience control voltage at work, or you can quickly copy and paste patches to your own projects.
