This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
* allow to update IR data
* allow to use mono processing in base-class
This is handy for FIR (Readable/ROM), and operating directly
on local data (ratherer than mapped buffers)
The previous approach failed in case where PluginInsert
uses no-inplace buffers with a linear map.
Since buffers are replicated up to a total of number of
all (inputs + outputs), the number of output buffers
could not be determined. There was insufficient information
using the I/O map alone.
With a known number of outputs processing and applying
the i/o map is also a lot easier and faster.
This break the API of process_map().
