currently only csound score or note events can be generated in real time (as opposed to instruments, which are only definable at compile time, when csound first starts; in csound 6 this limitation is removed). the set of sound processors is defined and compiled at load time, but the individual processing objects can be spawned or destroyed in real time, input audio processed in real time, and output generated also in real time. note events can be triggered based on osc communications within an instrument instance, spawned by midi, or entered to stdin (by typing into a terminal or sending textual statements from another program). the use of csound 5 as a live performance tool can be augmented with a variety of third-party software. live event sheet within csoundqt can be used to modify the score in real-time. in addition, interfaces to other programming languages can be used to script csound. a paper detailing the use of csound with qt or pure data in real-time musical synthesis was presented at the 2012 linux audio conference the ounk project attempts to integrate python with csound while csoundac provides a way to do algorithmic composition from python using csound as backend. audivation's csound for live packages various opcodes into max/msp wrappers suitable for use in ableton live.
