OSC

Can be: - abbreviation for Oscillator.

- A technique to control (Software)Synthesizers and open architectures via Ethernet connection. So it is a protocol like TCP/IP on the internet or better: It is a protocol which works on TCP/IP basis and allows computers and other devices to communitcate without midi and at higher speed.

TCP/IP / Ethernet wasn't made for "real time" purpose, but with todays performance you can use it for most things and "MIDI replacement" if it's all computer domain and no Hardware Synthesizer is used..

OSC is open source and stands for open sound control.
