HELP!...  Experiencing PROTAMENTO problem when syncing Bars & Pipes
2.5 to tape using Syncpro accessory.
-Setup description:  A2000, Syncpro box, Roland JV880 sound module,
all communicating via Roland A880 Midi patch bay...  SMPTE set to 30
frames, all other DIP switches "OFF" on Suncpro box.

Right after startup (PRIOR to any syncing to tape) when sequence
played direct from B&P, everything is OK.  As soon as sequence played
via tape sync, extreme Protamento happens to sequenced notes.  If you
stop tape and try to play sequence direct from B&P again, Portamento
still there.  If JV patch is switched, then Portamento goes away (even
when original patch is tried again) UNTIL you sync to tape again...
then Portamento is back!  I tried filtering Control Change #65 with
Event Filter tool on both input and output sides of pipeline (during
playback only) but didn't help... disabled Control Change option in
both Midi In & Out tool/window, still didn't help...  tried manually
writing Control Change values to 0 in track note editing window, still
didn't help...  tried turning off Portamento and Control Change
options in JV, and tried filtering out Control Change messages going
thru Midi patch bay - sitll didn't help.  I also noticed some sort of
"loop"...  all notes in sequence are doubled...  Merge swithc is OFF
on Syncpro box (but signal is merged to the A2000 Midi In in patch
bay) and Midi In is NOT even hooked up on Syncpro box.  Manually
erased doubled notes but Portamento is still there.  I desperately
need help to get rid of this Portamento problem and stop the doubling
of all sequenced notes!  Can anybody shed some light on this problem?

thanks...
