Hi!
I want to support sample-accurate parameter automation
of my MusicDeviceBase based AU.
All of the examples I saw are calling GetParameter
once at the beginning of the render process. ..which
is very far from being accurate.
Are there some kind of parameter buffers? Like the
input buffers for incoming audio.
I feel uncomfortable with calling series of
"GetParameter"s for each sample. It feels to be a huge
performance hit to the DSP. Why not using parameter
buffers instead?
I'm also wondering why are all of those examples using
such an inaccurate parameter handing? (when someone is
using 512 samples long processing buffers, it doesn't
mean that he wants to get inaccurate parameter
handing)
Are hosts providing such inaccurate parameter
automation, or what is the reason?
Thanks for your time,
Greg1X
