Lexicon 480L Owner's Manual
Controlling a 480L from a Sequencer
Since you can control the 480L in real time with MIDI
controllers, it stands to reason that you could record
your manipulation of those controllers with a MIDI
sequencer, and then repeat the performance auto-
matically. In fact, this works perfectly, and this capabil-
ity gives the 480L a fairly sophisticated level of automa-
tion. If your sequencer can sync to tape, you can even
use it to provide automated effects for non-MIDI instru-
ments. For example, you can control the 480L from a
keyboard, recording commands onto a sequencer, but
the audio the 480L processes might be percussion,
guitar, vocals, or even the whole mix. If you perform live
with sequencers, there is no reason why you can't
sequence several effects processors along with every-
thing else.
When working with sequencers, it is always a good
idea to put the 480L on a different MIDI channel than
other devices in the system. This avoids the possibility
of the 480L responding to commands that aren't really
intended for it.
Keep in mind that as of this writing, no sequencers offer
"chase" mode for MIDI controllers. This may change in
the future, but for now it means that if you attempt to
punch in to the middle of a sequence, the 480L's
parameters will be in an unknown condition. To avoid
problems, always start the sequence at the very begin-
ning when overdubbing or adding new parts. Also, it is
a good idea to use the first measure of the sequence to
reset all the controllers to 0.

MIDI SysEx Data Dumps
MIDI Bulk Dumps
Bulk Data dumps are handled through the Control
mode as a Copy function. Moving the FUN slider will
scroll through the current set of Copy functions which
include Bulk Data Dumps; Dump Reg, Dump Mach A,
Dump Mach B, Dump All Internals, Dump All externals,
Dump MIDI Map A, and Dump MIDI Map B.
Selecting Dump Reg allows individual source registers
to be selected. After identifying Dump Reg as the MIDI
Dump type, simultaneously press STORE and REG to
initiate the dump (exactly like Copying individual regis-
ters).
MIDI Bulk Loads
Bulk data loads happen automatically on receipt of a
"send" command from the MIDI storage device if the
480L is not be in the Copy Prohibit mode. All Bulk data
loads can be selected to load to the internal or external
registers (manually selected) or they can be automati-
cally loaded in the original location (for eample, internal
registers reload to internal).
MIDI Automation
MIDI Automation via SysEx is enabled on Page 5 in
Control Mode. There are two states of AUTO: OFF, and
TRANSMIT. If AUTO is set to TRANSMIT, all LARC
movementswill have a corresponding data string out-
put attached.
