Bristol is synth emulation package for a diverse range of vintage synthesisers, electric pianos and organs. The application consists of a multithreaded audio synthesizer and a user interface called brighton. Note: If bristol is already installed on the build host, the build will fail. I assume the bristol authors have a good reason for wanting this to happen, so I don't alter this behaviour. If you want to try, edit the SlackBuild and add --disable-version-check to the configure command. Otherwise, do a "removepkg bristol" before building. This package uses POSIX filesystem capabilities to execute with elevated privileges (required for realtime audio processing). This may be considered a security/stability risk. Please read http://www.slackbuilds.org/caps/ for more information. To disable capabilities, pass SETCAP=no to the script.
