Ken, I also use the Raspbian distro and kernel with a few tweaks to
the Raspberry config (Jeremy has great documentation on this) and
that's it.

It serves me well i.e. as a guitarr FX + looper station, controlled
via MIDI footpedalboard and this mobile panel/control GUI interface
that I'm developing so I don't need any screen attached to the RPi
with. I also use an external USB sound card.

So you can start right away and then tweak as you go.
