The Yamaha AN1x Synthesizer mailing list

Hi Jon!

I haven't been able to follow the earlier comments about the
synchronization delay problem you're mentioning, but since I'm on the
verge of adding a PLG150-AN card to my MU1000R I have to ask you
about
some points out of the answer given by the Yamaha product manager Mr.
Burdette. I suppose he should answer my questions, but I start with
trying to get your opinion.

"....the triggering implementation (both internal and through MIDI)
is
a little different from previous instruments. But it does synchronize
perfectly with external MIDI clock messages recieved by the MIDI in
of
the CS6x®, S80 and S30...."

I really don't know which previous instruments he refers to. What is
different here?

"....The reason that it doesn't seem to sync properly is that the
actual arpeggio pattern is offset (delayed) by a 32nd note
(independant of tempo as it must be, to be in sync). This is a
predictable musical value that represents a "window" of
opportunity
that the arpeggiator gives you in order to determine how many and
which notes you wish to arpeggiate...."

I intend to slave the arpeggiator to an external tap tempo function.
Will I always be a 32nd note late? The last sentence seems a bit
cryptic. What do you get out of it?

"....When you are aware of this 32nd note offset, it is possible to
trigger manually (by anticipation of a 32nd note) to achieve the
desired result, and through MIDI by offsetting the arp trigger
note[s]
by a 32nd note...."

I guess I could learn to tap a 32nd early, but if precise results are
required this may not be possible. What if I slave some other unit to
the tempo tap, will there always be a glitch between them?

Just a few ago I tried a PLG150-AN sitting in a CS1x. Even though I
could only use earphones I could definitely hear the might of the
sounds and I really liked the arpeggiator. My two trusty Cyclones
I've
had for over ten years are great but hard to program. This one seems
so much easier  and all the patterns I tried sounded musical. OK I
shouldn't panic, but these news dishearten me a bit.

Best regards,
Lars
