supply. Look for this graphic on the power supply. Your
controller won't work with a center-positive power supply.
200mA MINIMUM
Zeppelin Design Labs offers a suitable power supply as an
accessory. Simply plug the cable into the back of your Altura under the "9v" label. This disconnects
the battery. It does not matter if you leave the battery inside. The only concern is if years go by and
you forget the battery is there, and it leaks all over your Altura.
2. POWER ON/OFF
Push the red button to switch the Altura on. The red LED on top lights up. Push the button again to
switch it off.
3. MIDI OUT
The Altura transmits data along one pin of a standard MIDI cable. We recommend you connect all
your MIDI cables before turning anything on. To use the Altura, simply plug a cable from MIDI OUT
to MIDI IN of any MIDI device; or use a MIDI-to-USB converter or other interface device to send the
Altura's data directly into your computer. See also "Function 7: Channel Select" on page 19 below.

1. POWER ON INDICATOR
This lights up when the power is on; off when it's off. This is a reliable indicator of whether your power
supply is working or not. If you run the Altura from a battery, this light will get considerably dimmer
rather suddenly when the battery is near the end of its life. Time for a new battery.
