Howdy Vartan,
Please try doing the following:
1. In your MIDI Device Configuration setup, uncheck the "Is input device" for all the LoopBe30 "Device" headings.
2. ALSO right-click on the Port(s) for the LoopBe30, and uncheck "Open for MIDI input (recording)".
3. In the MIDI Device Configuration dialog's menu "File", select "New..."
4. Save this configuration with a name like "LoopBe30 No Recording" (or whatever helps you remember it 
)
I think that having the Port setting "off" for "Open for MIDI input" should do the trick. Otherwise every time that Composer detects a MIDI signal coming from that port, it will automatically treat it like an input device (which is what you've been seeing). Turning the port itself off should effectively "turn the spigot off" so no signal can come back to Composer.
I don't have LoopBe30 installed, so I can't test this myself. Do let me know if it does (or doesn't) work.
ttfn,
Sherry
p.s. Good sig
