sorry, I was in a hurry and being a bit cryptic, Alt-v is a standard
shortcut, a prefix for a set of two key shortcuts. So (unless your
shortcuts are customized) you should see the status bar at the bottom
change to say what possible second key-strokes are expected. Alt-v,1
installs a change to voice one etc. These are "change of voice"
commands, installing a directive at the point where the cursor is; they
live in Directives->Typesetter->Voices, hopefully you could locate these
via the Command Center. There are also commands under
Staffs/Voices->Voices to set the initial voice for the staff. The use of
the term voice here (LilyPond's voice commands) is somewhat in conflict
with its use in Denemo where "Voice" means a staff that is typeset on
the staff above. I think this is clarified in the manual (f1)

I've typeset three of the bars in the attached, this has shown up a bug
with the newly introduced organ template and with adding voices (they
don't get the instrument sound automatically).

hmm, something wrong with the packaging - this needs a bug report to
Debian

well, I guess it depends on where you want to get help from :) But
seriously, the binary packages from denemo.org, although they gobble
space do avoid fights between packages over which version of the
libraries should be installed.
I build it, of course, and haven't had any problems doing that from
Debian stable in many years. The website lists the packages needed.

Thank you! that's three bug reports generated from just one email :)
