## Description

Please note that a more recent version (3.5), is available at: 
https://undefinedbehaviour.gumroad.com/l/upisketch
===========================================

UPISketch is a new kind of composition tool, that keeps the principle of “pitch versus time” of the classical score, extended in the continuous domain. It allows to freely draw 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.

New with Version 2: 
Amplitude curves have been added
Live Synthesis: we can monitor the score in real time at the position given by the playhead
Groups, and group duplication
List of gestures showing unfoldable groups
Much improved Undo / Redo
Solo monitoring
Smoother pitch glissandi
More display options
Zooming with mouse wheel (desktop version)

… and other fixes…
