Sorry, my sentence is a bit mysterious. In my plugin I don't use the
kernel mechanism, and when i fill in my AudioUnitParameterInfos in my
class' Initialize function mHostCallbackInfo.beatAndTempoProc is always
0 even with logic. And that's why i need to change a parameter info
afterwards.
I'll make a beta of my plugin available to download...and right now
it's really designed to work with host that have transport
informations....
Thanks again Marc
Franck
