Thanks a lot for this. At first I was confused at the difference between the instruments in Csound.Catalog, and those in Csound.Patch, but once that was sorted out it was a very easy package to work with. Not having to depend on another full-blown score library is a good idea (in this case it would be redundant, because my library *is* a kind of score library).
Here's the first thing I did: https://soundcloud.com/ejlflop/guillaume-costeley-seigneur-dieu-ta-pitie-in-19-tet-tuning The patches sound very nice, and the slight randomisation of attack works very well! thanks, Edward Anton Kholomiov <anton.kholom...@gmail.com> writes: > Alas there is no CsdSco typeclass anymore. > The original idea was to implement score type with > the most basic type and give the user a chance to write converters > and use score playing functionality by the class CsdSco. > But I've noticed that this approach was preventing me from using > advanced score structures (they are implemented in the separate > package). > And type signatures become scary for the novice. > So I've settled down the type.
