REAR PANEL FEATURES
1. 9v DC POWER INPUT
You can power your Altura MkII with a plug-in 9v DC
power supply (“wall wart”). It must be rated for 200 mA
minimum, with center-negative polarity, such as a typical
guitar pedal supply. Look for this graphic on the power
supply. Your controller won’t work with a center-positive
power supply. Zeppelin Design Labs offers a suitable
power supply as an accessory. Simply plug the cable into the back of your Altura MkII 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 MkII.
2. POWER ON/OFF
Push the red button to switch the Altura MkII on. The red LED on top lights up and the display does
a little dance, followed by a letter and number, indicating the current key and scale. Push the button
again to switch it off.
To display the software version on your unit, turn all seven knobs far left, then power on.
3. MIDI OUT
The Altura MkII 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 MkII, 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. A common problem stems from use of inferior-quality
MIDI-to-USB cables. Use a quality, name-brand device from a reputable dealer who will help you if the
cable proves defective.
