i'm using an A-191 LFO to externally clock the A-154 sequencer
controller, the A-191 gets midi clock from my midi interface. 
lately i've noticed that the sequencer is a bit 'late' - i.e. it is
e.g. almost 1/32 too late at 100 - 120 bpm. 
i've already tried all sorts of permutations (taking clock from A-190,
using a different midi interface as clock provider, bypassing A-154
and putting clock directly into the 'old' sequencer control unit) and
nothing has helped.
is anyone familiar with the problem? what could be the reason for
this? is it possible that the sequencer needs to be repaired (it seems
to work just fine otherwise)?

thanks and regards,
