More EDP sync problems

[Geoff Smith <geoff.smith15@btopenworld.com>]

ARGH!
I have been trying to get my Akai MPC to sync to the midi clock of my edp
loopIV
that i have a pre-recorded loop I like on.
However all is not going well.
as the Mpc is not being triggered by the EDP.

I have tested the mpc.
When using logic (transmit midi clock) the mpc starts when i press play and
reads the midi clock and then loops along in sync perfectly. Therefore the
mpc is responding to midi sync fine.
Okay so this leaves the edp.
When i connect my EDP loop iv with sync set to out the mpc does nothing!!
and if I press play on the mpc it simply plays the sequence at its original
tempo and not the tempo of the edp. So how do you get a sequencer to sync 
to
the edp when u have already recorded the loop before?
How to you send a start sequence command to the mpc like what happens when 
i
press play on logic.
ARGHH!
bizarrely if i connect up my loopIII edp and create a loop the mpc jumps
into play and syncs beautifully. So how do you sync to a loop u recorded
earlier????
This is driving me up the twist.

At this rate i am gonna give up with the edps and use the psp42.
Damm Damm damm
I must be missing something obvious.
Can anyone help???
