Hi all, As a big fan of alternative tuning systems and microtonality, the desire naturally occurs to me to seek out synthesis tools which make this possible. I also happen to think 'whysynth' is a nice application whose general felxibilty and sound make it worthy of having some of the more microtonal-aware capabilities of for example, "ZynAddSubFX", but it seems that zyn is no longer in active development, and is sometimes oddly bug-ridden and unstable. So, after having located the code snippet in whysynth that creates a standard 12-equal tuning array, called 'y_pitch', as factors relative to 440HZ (A440), and indexed by MIDI note numbers. I wonder, how easy would it be to make this table dynamic and subject to for example, loading a SCALA .scl file, or at least, a user defined array which can be loaded from a dialog box? here's the code snippet from 'whysynth_voice_render.c' /* MIDI note to pitch */ for (i = 0; i <= 128; ++i) { pexp = (float)(i - 69) / 12.0f; y_pitch[i] = powf(2.0f, pexp); } My GTK experience is nil; my programming chops are strong in Python and TkInter, but not as strong in C/C++....perhaps someone who might be interested in such a venture could point me in the right direction, or be of some assistance?
