Notes about the ORC file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The ORC file type is primarily associated with 'cSound' by Csounders. cSound is open source sound software. ORC is a text file containing instructions in the CSound programming language. It defines a set of instruments for music synthesis. CSound uses a "Score" file (extension *.SCO) to define what notes to play on the instruments defined in the *.ORC.
