Sorry about replying to myself but I've played with this some more and
it does seem to do what it says on the box.

I created a gimp gap animation of a few slides (pic_00001.xcf,
pic_00002.xcf etc) and opened the first one manually. Then I mapped
"note 00 on" (on channel 15) to plugin-gap-next and "note 02 on" to
plugin-gap-first. Finally, I connected a vkeybd to gimp in qjackctl.
Playing low C's stepped through the slides perfectly and low D restarted
the show. The only caveat is that, if you wish to use a spare MIDI
channel rather than respond to every channel, you will need to apply the
patch I mentioned above to your install of gimp.

Hope this is helpful to somebody.

Simon
