>>Can user in Cecilia build Csound instruments in a similar manner > >>than one builds in Reaktor? Many disagree with me I'm sure, but I think that once you really learns the csound paradigm, you'll find that the visual style of Reaktor and PD just doesn't make sense for building Csound instruments. They are two very different ways of approaching synthesizer programming, and it seems to me most people getting into Csound wish they had a GUI builder at first, and then after learning Csound better realize that Vim/Emacs and a scripting language are a lot more powerful for building Csound synths. Personally, I find the Csound way much better for complicated instruments, while it is harder and has more coding overhead for simple one. I like GUIs *for* Csound instruments, but I would never want to make a Csound instrument *with* a GUI. I think it would hide too much of the low level access that makes Csound so exceptional. Iain
