MOTU has updated their site with more information on Volta, its virtual instrument plug-in designed to turn your audio interface into a voltage-controlled interface for traditional analog gear.

With Volta, any hardware device with a control voltage (CV) input can be placed under digital control from your audio workstation software. You can play and automate modulars, analog synths – even effects processors.

Here are some examples of what you can do with Volta:

• Perform MIDI sequencing with external modular synths with sample-accurate precision (if your host sequencer supports sample-accurate MIDI).
• Automatically calibrate and tune oscillators with the click of a button.
• Use ramp automation in your host audio software to control filters, envelope generators, effects processors and other voltage-controlled external gear.
• Apply LFOs, step sequencers and pattern sequencers to CV inputs and tempo-sync them to your host software timeline.

In the demo video above, via gearjunkies, MIDI notes are triggering oscillators, ramp automation data is controlling filter cutoff, and MIDI controller data in the MIDi track is controlling filter.

Volta features

• Standard virtual instrument plug-in that turns an audio interface with DC-coupled outputs into a voltage control interface.
• Lets you control external modular synths or other CV-equipped gear from your computer.
• Works with Digital Performer, Logic Pro, Live and other Audio Unit instrument hosts that support side chain outputs.
• Works with any MOTU audio interface equipped with TRS outputs, including the 24io with 24 TRS outputs, expandable to 96.
• Familiar, easy-to-use instrument plug-in operation within your favorite host software.
• Provides 24 control outputs per plug-in instance. Use as many instances as needed.
• Converts MIDI track data to control voltages to play modulars, analog synthesizers and other CV-equipped sound sources.
• Sample-accurate MIDI playback with supporting host software (such as DP).
• Provides seven different control source types, including MIDI notes, MIDI controller data and audio track automation, plus tempo-synced sources such as LFOs, clock pulses and trigger/pattern sequencers.
• Provides one-click pitch and octave calibration per oscillator using either Hz/V or V/oct tuning standards.
• View at a glance the total calibrated range for each oscillator/interface combination.
• Sync multiple drum machines, arpeggiators and other clock destinations with independent PPQ resolution for each device.

Availabilty and pricing are to be announced.
