Hi
i have fixed the tempo by using MTC sync between Samplitude mtc master and protools hd MTC slave.
i put the frames to 29 is drop in samplitude and protools and put 2 on smpte offset and 2 drop rolls frames in the samplitude smpte sync setup.
for audio i put 182 samples (the system delay of protools) in record offset in protools.
everything seems to be right
the refx vanguard arpegiator is in sync with samplitude tempo.
the smpte sync between samplitude and protools have the same value.
MTC between samplitude and protools work hard !
best regards phil
