This app transforms a DC-coupled audio interface into a MIDI to CV converter. It generates control voltages from MIDI data to operate external analog synthesizers, modular systems, and sequencers. Multiple audio units offer diverse functionalities for music production.
1.2.3
July 24, 2023
This version fixes various issues when the AU's are running under Logic Pro: CoVariantAU and TriggerAU: could stop responding when Logic is looping. ClockAU: could be 8ms out of sync with Logic's audio and could stop responding when Logic is looping. PolyphonyAU: would fail validation. Also fixes the broken hyperlinks in the documentation index.
MoreCoVariant is a set of audio units that convert MIDI data from a host app into control voltages (CV/Gate) for analog synthesizers and modular systems. It requires a compatible host application to function.
No, CoVariant audio units do not run standalone. They require a compatible host application that supports multi-channel audio interfaces to load and operate them.
CoVariant can control external analog synthesizers, modular systems, sequencers, drum machines, or any other analog equipment that accepts control voltage (CV) signals.
CoVariant includes CoVariantAU for MIDI to CV/Gate, TriggerAU for simplified control, ClockAU for synchronization, PolyphonyAU for polyphonic control, and EncoderAU for Eurorack module integration.
CoVariant requires a host application that supports multi-channel audio interfaces. GarageBand is not suitable due to its limitations. It is available on iPhone, iPad, and iPod.
The accuracy of the ClockAU is dependent on the timing and transport state data provided by the host app. For optimal performance, ensure your host app provides stable and accurate timing information.
CoVariant is available for a one-time purchase of $7.99. There are no in-app purchases or subscription fees associated with this application.
CoVariant was last updated on July 24, 2023, with version 1.2.3. This indicates ongoing support and potential for future improvements.
