The Console Fader Automation of adt-audio offers 0.1 dB level accuracy, db linear over a range of more than 100 dB. The dynamic system can handle scan rates up to 1/4 frame. With a 25 frame time code, the console is updated 100 times per second.
"The bandwidth limitations of the serial Musical
Instrument Digital Interface (MIDI) protocol used by
many control surfaces creates a tradeoff between
responsiveness and the number of controls. With 31.25
Kbit/s MIDI, for example, a maximum of 35 controls
can be controlled in a 33 ms video frame interval
(assuming three byte MIDI commands)."
"In addition to bandwidth limitations, many of the MIDI
protocols have insufficient resolution in their data types,
for example 128 discrete values for a knob, compared
with over a thousand discrete values that might be
necessary for accurately choosing an EQ frequency
working with a mouse and DAW - as far as i know - the resolution of fader-values are depending on the number of pixels on the monitor. this would mean that a faderride on a big screen "sounds better" than on a small one, cause more points/values are represented. or did I get this wrong?
