No that's my Arduino based Swis-army-knife midi controller :)

The Pi itself is uncased, and just about visible at the back of the desk the far
side of the speakers - to discourage stray fingers.

It's a Pi 3B running a fairly minimal Rsapbian, and the setup for the show was
with a mid-range monitor, a small USB->stereo audio module, small keys midi
keyboard. The audio was sent to two inputs of the KA6 so it could be heard on
the same speakers as the larger setup.

For a couple of guys who were particularly interested, I also ran it headless
with the monitor switched off - perfectly practical but you do need to be able
to remember the shortcuts... or have a crib sheet :)

Currently, I have even better results running with the minmal Devuan
ASCII 2 with no GUI elements at all and only absolutely necessary services. It
definitely runs significantly better as a pure ALSA unit than with JACK. The
same audio adaptor can drive most headphones directly, so the only other thing
needed is a standard keyboard (no mouse or monitor).
... Oh, and a power supply.
