- Updating Csound with RPM on a XO
- Csound TOOTS An Instrument Design TOOTorial by Dr. Richard Boulanger
- A Beginning Tutorial by Barry Vercoe.
- Chapter 1 from The Csound Book The complete first chapter from The Csound Book, by Dr. Richard Boulanger

Exploring Csound from the XO Terminal
Downloading with wget
The terminal utility wget downloads files directly from the internet. The following example downloads 4csEditor.zip, a library of approximately 500 Csound csd files:
wget http://csounds.com/4csEditor.zip
Unpack Files
Downloaded files usually come in one of three archival formats: tar, tar.gz and zip.
- tar xvpf file.tar Unpacks a tar file
- tar xvpfz file.tar.gz Unpacks a tar.gz file
- unzip file.zip Unpacks a zip file
Flags
Flags change the behavior of Csound, and can be set either in a Csound csd file or by specifying them at the command prompt. The following is a list of the most common used flags in both Csound-based activities and the Terminal activity:
- --help A complete list of supported command-line flags for Csound.
- -odac Output audio stream to the Digital-to-analog_converter, sound card
- -iadc Read audio from the Analog_to_digital_converter, built-in microphone
- -d Suppress all displays
- -m0 Set message level to 0
- -b2048 Set sample frames per software sound I/O buffer to 2048
- -B4096 Set samples per hardware sound I/O buffer 20 4096
- -+rtaudio=alsa Set real time audio to the device alsa
- -+rtmidi=alsa Set real time MIDI to device alsa
The following line shows one possible example of rendering a Csound csd file named foo.csd in real time.:
csound -odac -d -m0 -b2048 -B4096 -+rtaudio=alsa foo.csd
Users can hardcode flags directly in a Csound csd between the markup tags <CsOptions> and </CsOptions> with a text editor such as vi:
<CsOptions> -odac -d -m0 -b2048 -B4096 -+rtaudio=alsa </CsOptions>
