Wolff Audio ProPatch 1.1 Adds MIDI Automation, More

ProPatch units are based around a proprietary relay-based, software-controlled passive switching architecture that provides direct, balanced routing without coloration. Control is available via Mac and Windows applications, offering instant preset recall and session management. The units offer support for all signal types including mic, line, phantom power, control voltage and MIDI. The software itself is based around a drag-and-drop interface that allows users to create complex signal chains, offering A/B comparison functionality and mult capabilities, as well as full MIDI support for automation control.
