Yeah, that's what I was thinking as well, but I don't quite like the extra "+ global_tuning" whenever you're doing pitch->frequency conversion... Especially since you might as well have a "TUNING" control on sequencers, scale converters or whatever you're using. > It would be good to let the host provide the figure and the > instruments can just pick it up.

They have there own 0.0v -> Hz mapping, set via a dial. Well, we don't need to deliberately disconnect some kinds of plugins from global tuning, do we? ;-) > I dont see any point in specifying it as middle C. No, anything works. Better have nice values, like 440 and 435. //David Olofson - Programmer, Composer, Open Source Advocate .- The Return of Audiality! --------------------------------. | Free/Open Source Audio Engine for use in Games or Studio. | | RT and off-line synth.
