I have a few questions on Audio Units, I'd appreciate any help.
1. How is it possible to pass variables from one Process() run to
another? I mean there are things needed to remember like oscillator
phases and such, but where do I define these variables? Will simple
global-scope variables work?
Have a look at the FilterDemo code in the CA SDK (/Developer/Examples/
CoreAudio)
2. Is there an "Integer" parameter type? What I want is a slider
which would step from, say, 1 to 10 in single steps (1, 2, 3).
Yes - declare the parameter as an indexed type - there's an example
of this in the SampleEffect unit in the SDK
3. Where should the plugin "instantiation" code be placed? What is
the best way to initialize some data which would be accessible in
Process()?
