Etherwave® Plus User’s Guide
The Etherwave Plus is an expanded version of Moog Music’s classic Etherwave theremin, using the same great-
sounding and easily playable theremin circuitry that has made the Etherwave our best-selling theremin. The Etherwave
Plus adds the following features to the standard Etherwave theremin:
• Pitch CV output – The Pitch Antenna can act as a CV (Control Voltage) controller for any external CV compat-
ible device, such as Moogerfooger® Analog effects, the Minimoog Voyager® analog synthesizer, the Little Phatty®
analog synthesizer or the Moog Guitar. The Pitch CV is generated from the pitch of the theremin waveform.
Nominal output is -2.5V to + 4.5V. Zero Volts is output when the theremin produces a pitch one octave below
middle C (approx. 131Hz). The Pitch CV output is factory-calibrated to produce a change of 1 Volt per octave
change in the theremin’s pitch.
• Volume CV output – The Volume Antenna can act as a CV controller for any external CV-compatible device.
The Volume CV output is generated from the same CV signal used internally for the Etherwave’s VCA circuitry.
Nominal output is 0 to +10V.
• Gate Output – The Gate signal can be used as a signal to start envelopes, trigger sample and hold circuits or
other timing related activities.The Gate signal is generated when the Volume CV rises above 0 Volts AND when
the theremin audio is greater than 0 Hz. OFF is 0 Volts and +10V is ON.
• Headphone output with headphone volume control – can be configured with an internal jumper for normal or
“pitch preview” function.
• Power Indicator LED - indicates when the unit is on and ready to play.
This User’s Guide only describes the added functions of the Etherwave Plus. For information regarding the operation
of the Etherwave Plus’ basic theremin functions, please refer to the Sections “Setting Up and Playing the Moog Music
Etherwave Theremin” in the Etherwave Theremin User’s Manual.
