I understand the Echo harp has the octave notes over and under...so if I play an octave split on this harp it doubles...and if I play the split thru an octave pedal? How many octaves? how many are duplicated? WIll it sound like mud?

It depends on how you do it? Say your octave harp plays a C3 and a C4 when you blow in the hole. You do a split and add a C4 C5. Then you shift it down an octave, split, and you add a C2, a couple C3, and another C4.
1 C2
3 C3s
2 C4s
1 C5
Now, if you shift the pitch up, or do a fat double octave tongue split it makes it more complicated.
Just the double octave tongue split into the splitter would give you:
C3/C4 C5/C6
If you shift that down you get:
1 C2
2 C3s
2 C4s
2 C5s
1 C6
I suppose you could turn the EQ up on the ends to even it out. My guess would be distortion could turn it into mud, but a nice clean note? That might be interesting. My octave pedal isn't particularly clean and I don't have an octave harp and my friend, who has an octave harp, would be hard pressed to do a tongue split (and I won't play someone else's harp). So, anyone out there with the right gear to make a recording of this for us?
Permutations:
Single note (blocking one hole so the second reed doesn't sound)
-pitch shifted up
-pitch shifted down
Single Octave
-pitch shifted up
-pitch shifted down
Tongue Split Octave
-pitch shifted up
-pitch shifted down
Tongue Split Double Octave
-pitch shifted up
-pitch shifted down
I suppose you could try blocking one row and doing each of those, but it would basically be the same as just playing a normal harp. There are 4 C notes on a regular harmonica, and someone, maybe a U blocker, might be able to play 3 of them while blocking all the other notes.

Go nacoran!
You have it broken down well. I hope someone can help. Got my curiosity.

I don't have an octave tuned harp, but I do have an octave doubler patch on my RP155, and I have played tongue split octaves through the octave doubler. It actually doesn't sound like much. The octave down effect really overpowers everything else. I've play Buddha's old HOG (that he, alas, sold on), and it had several octaves (I think it was 3 down octaves and 2 up?), and I played a split octave through that thing. Now that was a lot of octaves going on! Maybe a bit fuller than a single note played through it, but my memory is fuzzy now.
