UPISketch4

UPISketch is a composition tool that keeps the principle of “pitch versus time” of the classical score, extended in the continuous domain. It allows for freely drawing absolute pitch curves applied to existing sounds. It uses granular synthesis. It can be used to sketch musical ideas, try alternative scales (divisions of the octave), and more.
It is inspired by the famous UPIC machine that was invented in 1977 by Iannis Xenakis and the CEMAMu engineers.
Version 4 introduces significant changes: improved sound quality, sequence recording, and a magnetic grid feature.
