Continuum Control of the Moog Voyager

Edmund Eagan

In these audio examples the Continuum is being used through the CVC to control the Moog Voyager without the use of Midi. A collection of STS Serge CV modules were used to process the voltages coming from the CVC before they were sent to the Voyager. This approach allows unique blend mixtures of the Gate, X, Y, and Z voltages from the CVC into the voltage inputs of the Voyager.

1. The Continuum performance data is sent to the Continuum Voltage Converter (CVC) via it's i2c data connection.

2. The CVC processes the data and generates Gate messages as well as voltage conversions of the X, Y, and Z positions of each finger. In this case only the first four voltage outputs (16 are available) were used.

3. A Sound Transform Systems Serge module collection of voltage processors blends the source voltage inputs from the CVC. Scale, offset, invert, mix and gated ADSR signals shape the voltages for output.

4. The blended outputs from the Serge modules are routed to voltage inputs of the Voyager. The blends typically were:

Volume: A mixture of the continuous Z from the Continuum with an ADSR Serge envelope.

Filter: Perhaps the most useful to blend, as the Moog filter is so rich and imparts a distinctive sonic character to the sound. X input simulates traditional keyboard tracking, Y is typically used for a broader filter pitch change, and Z can create a "louder is brighter" tonal change, although sometimes it was useful to invert that value. An ADSR shape was used for some of the sounds.

Wave: X Y Z inputs were used with an offset voltage, typically used to place the triangle wave shape at a particular Y point.

Mod 1: A blend of X Y Z used for the multi destination routing point.
