i can open a soundfile but i don't hear anything when playing back
here's a list of possible reasons and hints:
- the SuperCollider server isn't running. at the bottom of the main window, there should be printed a valid sampling rate at which the server runs, the button on the right should read "terminate" to indicate the server has been booted. Check the meters in the control room palette: if they don't move, the server communication isn't working.
- if the server is not running, press the "Boot" button in the main window to launch it. If an error occurs, verify the preferences settings for the SuperCollider server application, the audio interface, and the sample rate.
- assuming SuperCollider is running. check for error messages in the console. known issues include pathnames with special characters and certain soundfile formats (e.g. IRCAM 24bit int doesn't play back). The error message "Exception in World_OpenTCP: unable to bind tcp socket" when booting SuperCollider indicates that a server was booted before but not properly quit. You can kill unresponsive servers by choosing Debug->killall scsynth.
- check the main volume and the main output configuration in the control room window. Also check the audio device used. In the console window, look for the "Output Device" used by SuperCollider (the device name is printed when booting). On Mac OS X it's possible to accidentally boot a device without output channels (e.g. built-in microphone).
- try to quit and relaunch eisenkraut. try to quit and relaunch the supercollider server. try to close and reopen your document. try to convert your document to a different soundfile format.
my soundcard don't show up
currently, eisenkraut has no means of finding out automatically about the connected audio interfaces. instead you must create an "audio box" manually in the audio box preferences. supercollider will print out all available devices in the console when it's booted, so you may pick up the correct device name from the console.
what happened to Process->Silence
?
the same functionality is available by choosing the Overwrite
edit mode and Edit->Clear
.
what happened to Process->Mix
?
a similar functionality is available by choosing the Mix
edit mode and pasting audio. if you need to adjust the mix amount, copy first into an empty document, adjust the gain using Process->Gain, then paste in Mix mode.
