Of course, as we're all using these strange loop things, here's a 
concept to escape the limitations of diatonic tuning.
You need: a looper which has more speed settings than 
normal/half/double. I personally use Mobius a lot, but something like 
e.g. an Eventide TimeFactory, Lexicon 84, EH SMM w/Hazari etc. will also 
do fine (Rick, I would expect the LP-1 can do this as well?)

Sticking with the C Ionian (major) example, play a melody into the 
looper. Then do a varispeed, and get any of the chromatic pitches you 
desire...depending on which speed factor you use, more or less of them 
(e.g. 3/2 original speed = 5th up = you get an f#, 4/3 original speed = 
4th up = you get a Bb etc.), which you can then use againts the 
live-played diatonic instrument.

Now to wrestle this back on topic regarding odd time signatures: the 
loop does not only change pitch, but also tempo. So if your loop 
originally had a length of two bars (let's stick with the 5/4 example - 
that would be 10 4ths), after shifting it up a 4th, it's now 
10/(4/3)=15/8ths long, but if you played a quarter note before, this is 
now a dotted eight.

So play your original two bar melody into the looper, varispeed it to 
4/3, and continue playing your original melody on your diatonic 
instrument - polyrhythm and chromatic tonality from a diatonic 
instrument all in one looping box!
