We aim for composing algorithmic music in an interactive way with multiple
participants. To this end we have developed an interpreter for a sub-language
of the non-strict functional programming language Haskell that allows the
modification of a program during its execution. Our system can be used both for
musical live-coding and for demonstration and education of functional
programming.Comment: 10 pages, 2 figures, Linux Audio Conference 2013. This is a
