EDP Won't Play live reverse (using the PMC-10) in LoopIV

["Gary Lehmann" <healthquestrecruiter@earthlink.net>]

I tried out some of the PMC patches on the new OS.  I have found loss of
functionality on a cool setting and am unsure how to achieve the effect.  I
documented this in January--it's in the archives as
http://www.loopers-delight.com/LDarchive/200201/msg00699.html
but here's the text--
Here's an approach to the live reverse thing that I programmed tonight--see
if this is new to anybody but me.
I'm using the PMC-10 MIDI pedal to control the Echoplex, and I have been
using a momentary setting with string A double multiplying and string B
double recording (I pretty much have quantize on all the time), thus 
working
as a "set the loop" switch.  This works well for changing the time
signature--swell for turning 4 into 3, 8 into 7, bla bla bla--
I also have a pedal setting for "reverse now"--again something pretty 
doable
with quantize off and insert on rev, but I don't have mine set up that way,
so it's a parameter punch, then undo.
Well, I combined them, and then ran the feedback to 0.  Now, if I have a
blank loop, I can play something and have it play back reversed one time 
(or
more, with feedback higher, but I find it more effective if it doesn't
repeat--kinda like Andre's Loopfeste opener).  Again, for those of you with
the right MIDI pedal, that's:
Multiply on string A (when you press down), and record, parameter, undo
(when you release).  This assumes you have quantize off.

Now, I have only had the new OS for a few hours--but the desired effect is,
create a one time playback (in reverse) of new material.  This worked
before, but now it turns off the loop.  I have tried some different things,
but since live reverse is (and has been) listed as one of the features of
the EDP, perhaps someone can suggest a good way to do this with the new OS.
Here is the request, one more time--

Set the size of the loop, and play back the material, in reverse, one time.

Thanks in advance for any help
