That oughta work! :)

Ah, now there are a couple of things worth thinking about if you're
trying to get a three-note chord:
First, depending upon your shifter, you may be able to do this simply
by routing to a single pitch transposition device. I'm using an
Alesis Akira, for instance, and it will let me output two entirely
different transposed voices. I route out Aux 1 to the Akira, then
use MIDI CC's to control the interval of the two harmonies. The
Akira's Mix knob controls the balance between the transposed voices
and the original signal, resulting in quick-&-dirty triads. I know
other devices will do (at least) two harmony voices, so you may be
able to do what you want with a very simple setup.
Second, if you're going to try this with single-harmony transposers
on both Aux Outs, you're going to have to add some commands in there
to copy or bounce tracks. IIRC, an LP1 track can only access a
single output. I put in a feature request a while back to change
that (wishlist item #19, also details at:
http://www.looperlative.com/phpBB3/viewtopic.php?f=1&t=88&p=2485#p2485
) but I don't think there's been any progress yet. To output the
same track through all three Outs (Main, Aux 1, & Aux 2) you have to
copy the original track over to two more tracks. You then need to
set Track 1 to Main, Track 2 to Aux 1, and Track 3 to Aux 2.
Of course, with a Mix control on either of the pitch shifters, you
can bleed the original signal through and possibly save on one track.
This overall methodology does start to eat tracks, though, so be
aware and plan ahead.

Sweet. I used to do that with our samplers years ago (old Emu
Emax's, SCI 2000-series's, etc., etc., etc.; kinda dating myself
here, i guess). I lost many an evening just standing there in the
dark watching the lights blink and listening to the parts play
against each other.
One other thing that helps with this time stretch gimmick is if you
think of the LP1's transposition ability as the "Time" control, and
the shifter as the "Pitch" control. I've gotten plenty of ideas by
considering the LP1's transpositions solely as the ability to stretch
the time of a loop between 1/4x and 4x it's original speed; then
viewing the shifter as what ultimately determines the loop's pitch.
For instance, copy a melody track and drop it to half-speed -- just
as you did with the drums above. However, now set the pitch shifter
to only +7 semitones. Now, you have the second melody track moving
and half the speed of the original, and playing a harmony that is a
perfect fourth lower than the original track.
Add a bit of MIDI control, and you can control the harmony in real
time: perhaps shifting it to a fifth, an octave or a third below
during the middle of the loop. Or add a sequence to control the
harmonies. Bill Walker used to do some really way-out stuff like
this on his Repeater, and his stuff was just frickin' beautiful!
Lots of neat combinations there. Good luck! ;)
