I do not really understand what the problem is with using MIDI control
change for mixers. The resolution? For 2 data bytes there are 127 * 127
= 16129 steps. The number of channels? It's unlimited when using as much
IOs as needed. IMO there already is a standard for all apps, it's called
MIDI.
IMO automation is overrated, it's useful, but OTOH how often is it
needed to change settings during an opus? Most times a mix, selected
synth etc. are fixed from the start to the end of an opus. For example,
normally a musician plays an instrument dynamically by the touch or by
using a volume pedal. Dynamic for the loudness seldom is done by a fader
after the recording is done.
No doubt about it, we do need automation, but we don't need an
automation overkill, it just would make everything much more
complicated. 2 cents, Ralf
