Controlling Analog Synths from Software

Most analog synthesizers and some effects processors, eg. the Moogerfooger pedals, can be controlled by voltage. Such devices have "control voltage" ("CV" for short) inputs. MOTU has released a software product called Volta which can send CV signals, allowing for more convenient integration with a DAW (Digital Audio Workstation) such as Pro Tools, Logic, Sonar, Cubase, etc. It requires an audio interface with DC-coupled outputs such as MOTU's own audio interface products. I'm not sure if Volta can also receive control voltage.

If you have Cycling 74's Max, you could try implementing something similar in Max. This discussion thread has more information.
