Volta is a virtual instrument plug-in that turns your audio interface into a voltage control interface. Any hardware device with a control voltage (CV) input can be placed under precise digital control from your favorite audio workstation software. You can play and automate modulars, analog synths - even effects processors. Imagine being able to play and automate your CV-equipped analog gear from Digital Performer, Logic Pro, or Live with the same level of control, precision and convenience as a virtual instrument.

Extended information

Here are just a few 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.

Whether you’re a seasoned modular synthesizer devotee or simply a computer-based studio owner dreaming of adding that rich, coveted sound only true analog synths can deliver, Volta finally enables you to easily incorporate CV-equipped analog gear into your computer-based studio with all the control, precision and convenience of a virtual instrument.

Technical specifications

* 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.

System requirements:
* Mac OS X (version 10.4 or later)
* An audio sequencer software package that hosts MAS or Audio Unit (AU) instrument plug-ins and supports multiple instrument sidechain outputs, such as Digital Performer, Logic, or Ableton Live.
* An audio interface with DC-coupled outputs, such as any MOTU FireWire, USB2, or PCI audio interface with quarter-inch TRS outputs.
* The proper cable type for your interface.
* External audio hardware which responds to control voltage signals, such as modular analog synthesizers, vintage monosynths, etc.
* A free USB port for the iLok USB key. Note that if you have multiple products which use iLoks for authorization you can consolidate multiple authorizations onto a single iLok;
