After many time working with virtual instruments, this thread Orchestral Texture v1
made me wonder how it would be to have samplers in supercollider. I implemented a sfz reader in Lua2SC and did a new release (v0.2) in which also NRT and lilypond scores generation had been updated.
You will find it here: https://github.com/sonoro1234/Lua2SC/releases/tag/v0.2
Even if there is no particular interest in Lua language, it can be a good start to implement it in sclang.
Hope you like it.
