The main discussion forums for Csound are the user list and the developer list. To join these lists, go to these sites:
This is the main Csound user group. This group deals with all questions relating to installing, running, and using Csound. This group welcome mails from new and experienced users alike.
This group is used primarily for developers, but end-users are also welcome. This was once the main resource for filing bug reports and sharing development patches. More recently, users have been using the Github ‘issues’ system. Both resources are valid places for sharing development suggestions, problems, or issues found with Csound.
