Power
Input
Plug the power adapter into a proper power outlet then con-
nect to the X-15.
MIDI OUT
The MIDI output jack is used to transmit all MIDI control in-
formation from the
X-15
to whichever MIDI device you wish
to control. Connect the MIDI cable to the 5 pin MIDI OUT
jack on the
X-15
and then to the MIDI IN jack of the device
you are going to control.
MIDI IN
This jack receives the MIDI signal containing the MIDI
messages. It enables you to “talk” to the
X-15
from an
external source such as a computer equipped with MIDI
ports and associated software or a sequencer. Actually, you
may use any MIDI device to send messages to the X-15.
Any MIDI information sent to the MIDI In jack is echoed to
the MIDI Thru jack.
MIDI
THRU
A MIDI Thru jack is provided on the
X-15
allowing you to
continue a chain of MIDI devices and let MIDI information
pass “thru” the unit to the next one. Information leaving the
Thru jack is a direct copy of the MIDI messages received at
the MIDI In jack. The information is buffered so the integrity
of the signal is not degraded when passing thru.
All MIDI
Jacks are standard 5 pin
DIN
connectors utiliz-
ing standard MIDI connections. No phantom power is
present on the unused terminals. ART recommends
these unused terminals remain unused.
See Appendix B
for MIDI hook-up illustrations.

TELL-TALES/CONTROLS
NUMERIC DISPLAY
The Seven Segment Numeric Display keeps you constantly
informed of your Preset Number, Expression Pedal values,
MIDI Channel, Programming Characters, and Error Messages.
AlI information is displayed using decimal based numbers in
most cases.
Power up
When power is first applied to the X-15, it runs through an
autotest sequence turning on everything that lights up for
about a second, then it displays “Art” indicating everything
is fine. This allows the user to be sure that all display
elements are working and that displayed information will be
accurate.
During power-up the
X-15
performs a checksum of the ROM
contents, if there is an error, an error message will appear in
the display. If the ROM checksum is incorrect, “E-C” will
display for ten seconds, press any pad to operate normally.
In the event power is interrupted for a brief period of time
and the
X-15
does not reset itself properly, just unplug and
plug back in the power plug at the power in jack.
LED Indicators
LEDs located in the upper left hand corner of the activator
pads 1 through 10 indicate which pad is active. The MODE
and BYPASS activator pads have their indicator LEDs
located towards their upper right corner. These LEDs are
also used to indicate the different programming modes you
may be in.
Activator
Pads
Pads on the pedal are labeled from left to right: Select

When the pedal is in the full up position, a minimum value
is present and as the pedal is gradually pushed down, the
value increases to its maximum value when all the way down.
