OscVstBridge

OscVstBridge free routing by ByteWeavers

OscVstBridge is a free routing VST plugin developed by ByteWeavers. Compatible OS(s): Windows.

OscVstBridge is a VST plug-in that bridges VST data to the Open Sound Control [OSC] network domain.

VST plug-ins typically have parameters that are controllable by the user. These parameters appear as the knobs and sliders or as MIDI CC. By using OscVstBridge you can control via your MIDI controller or VST sequencer OSC devices that are networked to the controlling computer. Similarly OSC controllers can send messages to OscVstBridge that will convert it to VST parameter or MIDI data.
