Hi Niko - have you any useful information about how Logic handles this?
I'm specifying all my AU parameters as
kAudioUnitParameterUnit_MIDIController, and setting the
kAudioUnitParameterFlag_CanRamp flag.
In Logic, the resulting automatable parameters cannot be drawn as
ramped points, ie I can't draw an automation node with value 90, then
a little later draw a node with value 30 and have a smooth linear
ramp down. Logic continues at 90 then jumps down to 30 when it hits
that node, no interpolation of values takes place either visually or
functionally.
I note that it _is_ possible to draw ramped automation for Logic's
internal midi CC parameters, volume/pan/modulation etc.
Are kAudioUnitParameterUnit_MidiController and
kAudioUnitParameterFlag_CanRamp mutually exclusive? Or is this a
decision that Logic is making for some reason?
