ORC file extension - CSound Orchestra midi file

What is orc file? How to open orc files?

File type specification:

Audio and sound file type icon Audio and sound file type

orc file icon: orc filetype icon

The ORC file extension used by CSound for “orchestra” data info, was first used by the Orchestra-80/85/95/2000 Music Language and program/hardware originally used for the Radio Shack TRS-80 Models 1, 3, 4, 4P (with a hardware attachment of 2 8-bit DACs via their expansion ports for stereo output using software additive synthesis of up to 5 voices, each with 8-harmonic registers supported) and later (Orch-90/CC) the Color Computer Models 1, 2 and 3 (via a ROMpack).

Such ORC files were essentially text only files in upper case only, using a partial compression of the last characters at the end of each line, but setting its high “bit” to one, thus saving two bytes otherwise used for CR/LF control character terminators.

Help how to open ORC files:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert file with extension ORC:

As far as we know, this .orc file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
