Control Voltage

While the Whimsical Raps catalogue is historically rooted in our Mannequins offerings, we're sometimes self-conscious about noting the conceptual overlaps between Atrium and modular synths. And yet! As Atrium ventures into uncharted territory, proving the strengths of its own perspective & versatility, we know first-hand the joys of integrating tools one is already familiar with into a new environment.

So, with excitement for the conversations Atrium can have with a larger ecosystem of voltage-controlled sources, we've added three 3.5mm inputs for integrating control voltage (CV) into Atrium's lexicon. These inputs are located on the rear of the instrument, next to the audio outputs; demarcated on the panel with three grey triangles pointing inward. Through these ports, any CV source can be brought into the landscape of Atrium's modulation network.

The CV inputs respond to a +/-5V range. Signals up to +/-12V are safe to use.

Integration into Atrium is straightforward! Each input is simply a new source of mapping.

Map a CV input:

• Hold map and press cv to the left. Input a will be focused.
• Change focus among the three inputs (a, b, and c) by pressing the cv key.
• The focused signal will be indicated above cv, the light brightening according to the received voltage.
• Move the panel controls to dial-in mappings from the focused input.
• Press map to exit.

While it is safe to send signals outside of Atrium's expected range (+/- 5V), any signal outside this range will simply be clamped.

The CV inputs are bipolar, meaning they accept both negative and positive voltages. If you’ve performed a cv mapping and you invert the polarity of the incoming signal, its affect on the mapped parameters will also be inverted. eg: If you’ve mapped a cv source to increase timbre, sending a negative voltage will actually decrease the parameter.
