/* Filter chain. This would all be much simpler if we chose not to
* allow non 1:1 plugins to be mixed in a single chain...
*
* Supporting the mixture requires duplicating some inputs (to satisfy
* stereo input plugins reading mono outputs) and duplicating some
* plugins (to satisfy mono input plugins reading stereo outputs).
*
* Basically, what this means is that the intermediate number of
* buffers need not have any relation to the starting and ending
* buffer count. (Picture an ambisonic panner going into an ambisonic
* decoder (1:6:2).
*
* The chain will allocate enough buffers to hold data from the
* maximum number of channels used by a contained module.
*
* The process thread goes as follows:
*
* 1. Copy inputs to chain buffers.
*
* 2. process() each module in turn (reusing buffers in-place) (inputs
* will be copied or plugins duplicated as necessary)
*
* 3. Copy chain buffers to outputs.
*
* For chains where the number of channels never exceeds the maximum
* of the number of inputs and outputs, the first copy can be
* optimized out.

/* A mixer strip is home to some (JACK) input ports, a fader, some
* meters, and a filter chain which can terminate either at the input
* to the spacializer or some (JACK) output ports. Since mixer strips
* are not necessarily in a 1:1 association with Non-DAW tracks, there
* is no need for busses per se. If you want to route the output of
* several strips into a single fader or filter chain, then you just
* gives those strips JACK outputs and connect them to the common
* inputs. This mechanism can also do away with the need for 'sends'
* and 'inserts'.
