I do have a question though about ardour control by midi. The Mackie IF says it sends control messages that are in the form num of ticks up or down. This means I should be able to have a key send ticks up and another ticks down, but this doesn't seem to work.

It does work... but only into the the mackie midi in. It only seems to expect 0 to 100 ticks which is probably not enough for a fader anyway. This is probably due to physical limitations in the encoders, getting more than 96 or so ticks per full turn starts to get expensive real quick (10 to 1 or so... which answers the why use motor faders question). Changing controls on the gui while monitoring the midi out was very informative.

Ardour has an internal scaling factor for those ticks, or did at some point. The Mackie D8B mixer had similar issues with its scroll wheel. We seem to have removed it.

correction. the scaling factor was ONLY for the scroll wheel. faders work fine for me on an SSL Nucleus usng Mackie Control, which I strongly recommend (Mackie Control (or the Nucleus if you want to pay for it :)
