I guess people who like it tactile, prefer to feel the position of a
fader knob and btw. we likely want that it appeals to all senses, IOW we
also want to see the fader knob positions.
I have been trying to think what things are about tactile feel are helpful
to doing the job and what parts are pure resistance to change. One of the
things I have seen more than once on this list is "use your ears not your
eyes". Fader positions can be represented as LEDs or on a screen. I note
that while control surfaces generally use motor faders, they do not use
motor pots, but rather encoders. Some control surfaces have no indicator
where the virtual pot is, but rather show the effects on a screen beside
all the pots, for example a picture of the frequency responce for a group
of pots used for eq. Others have a light ring, but the light ring even for
something with 128 or more values only has 12 LEDs to show position. Some
highend surfaces have a dial shaped led display that might have 20 or so
LEDs right above the encoder. It seems we can only tell aproximatly where
things are with our eyes anyway.
Regarding to wheels also keep in mind, that faders
could be very long
but for an "endless" wheel you perhaps can't do the whole fade by
keeping the finger on the wheel, you perhaps need to set back the finger
to continue turning the wheel.
Design and training. I would actually think it would be easier to do a
full fade with a wheel or belt because the user is not restricted to where
the fader knob is, they can actually put their finger above where the
virtual fader position is.
would cost less. I wonder if longer faders would be
useful for the 128
MIDI steps.
1024 actually, 14 bits assigned, though not all are used.
