I think I have something else that may be another, possibly better, way to
achieve what your trying to do. It will also I think point out potential
problems that could arise.
The arpeggiators in the XX-7 are really part of a preset and not a separate
or distinct component in the XX-7. In other words for there to be any
arpeggiator operating there must also be an active internal synthesizer
channel.
The arpeggiator transmit MIDI setting (in the EDIT-ARP menu) when it is set
to "send MIDI" for the arpeggiation will *always* send the arp MIDI to the
external port and MIDI channel that corresponds to the internal synth
channel. In other words channels 01A-16A will send on MIDI port A 1-16 and
internal synth channels 01B-16B will send on MIDI port B 1-16. This is
"hard-wired" so to speak.
This interlocking relationship between an arpeggiator and an internal
synthesizer channel can have some interesting implications. The first is
that *any* arpeggio generated by the XX-7 will always have an internal
synthesizer channel active, and that channel *will make sound* unless it is
assigned a preset that makes no sound. So if all you want to accomplish is
to have an external MIDI device play the arpeggiator by itself you must set
the corresponding internal synthesizer channel to be a silent preset like
the "default" preset.
An active arpeggiator on *any* internal synthesizer channel will always send
MIDI if the ARP transmit MIDI setting is on. So it is not possible to have
some channels arpeggiating internally and some externally. If this is what
you want to do, have two or more arpeggiators working together, say one
external and the other internal, you will need a work around such as
follows.
As mentioned the only way to disable the arpeggiator from sounding an
internal channel is to assign that channel a silent preset like "default".
An external MIDI device can be prevented from responding to the arpeggiator
information by either simply disabling that MIDI channel in it's
multi-timbral setup (most modules have this) or if that does not work assign
it a silent preset. You will however loose the use of that MIDI channel.
[note that if you have some type of external MIDI router like a MIDI
patchbay or maybe something running in software you can create your own
routing that avoids these issues entirely]
If there is to be a lot of this type of usage, and you are only using a
single external module, or your total external module channels is sixteen or
less, consider hooking all of the external MIDI devices to MIDI output port
B on the XX-7. Now you will be free to use internal-only arpeggiators on
internal channels 01A-16A without needlessly interfering with your external
MIDI modules. When you want to use an arpeggiator on one of your external
MIDI devices you would simply assign the track to 01B-16B.
One last point about the use of the XX-7 arpeggiators. If you want to use
the arpeggiator with a recorded track (for example a track of chords being
played) to play an arpeggiator to an external module you must set that
track's destination assignment to an internal synthesizer channel only, and
the channel must be assigned a silent preset. The channel used would
correspond to the port and MIDI channel of your external module. You should
not set the track destination to either EXT or BOTH. If you set it to EXT
you will only get the chords sent to the external device (no arpeggiation),
and when set to BOTH you will get both the chords and the arpeggiation.
All of this admittedly seems a bit convoluted and overly complex. If you
remember though that the arpeggiator is really a special internal
synthesizer feature that "belongs" to an internal channel you will at least
be able to think through this complex maze.
Hopefully this will help if not now sometime in the future.
