Shouldn't be. I have used it with more than one USB keyboard and even a
Wiimote (bluetooth) controller. SO long as the keyboard shows up in
/dev/input/ it should work. The main thing is that it has to run in user
space because it uses Jack MIDI. This means the keyboard device has to
accessable by the user running jack. So I created a new group "input" and
made a udev rule to put the /dev/input/* files into that group. I then
added me to that group. I would not use the main keyboard but a second
one. anyway, I am willing to debug with you if you like.

Which? I am running open stage control on the same PC as the DAW right
now. An Android can run Chrome and control it via that, but I have been
using on the same machine for now for SW development testing. It does run
on the Pi though and I intend to use a Pi as the brain of my controller.
The screens (for now) will be cheap androids ($60ish). I am starting with
one fader group (8) and one master. The master might include 6 bus faders
as well as master and monitor control.

I have been able to control Ardour (with full feedback) using either
Control or touchOSC. There are OSC/MIDI bridges around (you may have to
use two, one for each direction) that would allow these to work with MIDI.
Both allow designing an interface with only the controls you need (what I
saw of touchdaw had way too many things on the screen for my fingers to
operate). Both send OSC or MIDI (I notice looking at my touchOSC editor)
so you may not need a bridge even. The bad news is that both have horible
faders/pots which jump to your finger touch rather than just moving in the
direction your finger moves after touching. Open Stage Control gets this
one right and is worth the extra setup steps for that alone in my opinion.
TouchOSC has slightly faster response than Control, but Control is free
and open and allows creating custom functions or even widgets (maybe
better faders?)

So just a controller then. MIDI should be easy no matter what you start
with (keyboard, Wiimote, tablet, toy midi keyboard from the thrift store)
I found a Yamaha PSS-480 for $18 in a thrift store. Each note can be maped
to a different control for transport... no faders, sorry.
