Hi Steve,
Sounds like what you need is a MIDI merge box. The factors only have MIDI xmit/thru and MIDI in. They cannot do both transmit and thru. That is, they are only a master or a slave. If you want your Moose to send messgae via the PF to the other pedals you'll need to have the MIDI output set to Thru, but then the PF wont be able send and control to the other pedals. Here the Moose is the Master.
If, however, you want the Moose and PF to both be able to control the other pedals you can merge their MIDI outputs in a MIDI merge box to that will send a single MIDI data stream to the other strictly slave pedals.
