Below some links to instruments specially designed for Csgrouper. These are either very basic Csound code or copied/adapted from free material put on the net by Csound experts. I’ve put the original author when I could gather this information.
The emphasis has to be put not on the sounds presented, but on the pre-treatment applied for Csgrouper, in commented out lines at the beggining of these instruments (‘Csgrouper param recognition’) as they make the instruments ready for Csgrouper X-functions (glissandi, pan, silences, amplitudes etc.).
