OSC/PILOT is a bi-directional control surface application originally built as a performance tool for digital artists and musicians. With this tool, you can make beautiful UIs in minutes. Multiple workspaces allow for different UIs to be used from within one project. Multi-Touch is fully supported. You can drive the UI with as many fingers as your touch display supports.
The utility allows you to send and receive OSC (Open Sound Control) data. You can send OSC data to control other applications and devices that support OSC. Thus, you can control visual applications such as TouchDesigner, vvvv, Resolume, VDMX, Notch etc. Also, you can send MIDI to other computers and applications using network MIDI tools such as rtpMIDI and loopMIDI.
