Report a Bug

Help improve Csound by reporting issues to the right repository tracker.

Csound is an ecosystem of projects maintained by several teams. Routing your bug report to the specific tracker below ensures the maintainers see it quickly.

A bug on this website (csound.com)

Example: You click on a link and get a “page not found” error.

Please report the issue on this site’s GitHub issue tracker. If you are not on GitHub, you can also email website at cs-conf.de.

A bug in the Csound core engine

Example: Opcode XYZ outputs 0 when the third input argument is set to 1, although the Reference Manual states it should output -1.

Please file an issue on the Csound Core Issue Tracker. Please include:
