QUICK START GUIDE
Look for the companion demo videos on our YouTube channel.
The Altura MkII is a MIDI controller and arpeggiator that emulates the classic theremin. The right sensor
transmits note data to set the pitch. The left sensor transmits a variety of MIDI controller data to influence
the sound in many ways. In X-Y mode, the right sensor mimics the left: both sensors transmit control
data of your choosing.
The Altura MkII features 20 preset locations to preserve your setups.
1. POWER UP
Use a 9v DC power supply or a battery.
•
9v DC power supply (“wall wart”): 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.) Plugging in the power supply
disconnects the battery.
•
9v battery: Use a high-quality alkaline battery, like Energizer. (Don’t waste your money on
cheap batteries!) Open your cabinet; insert the battery into its holder; snap the contacts into
place; and then push down to snap the battery into the holder. The fit is tight; you may need
to use a little screwdriver as a shoe horn to ease the battery into place.
2. CONNECT A MIDI DEVICE
Plug a standard MIDI cable into the Altura MkII’s MIDI OUT jack,
and connect it to the MIDI IN of your Macchiato Mini Synth or any other device; or plug into a
MIDI patch bay or other port device; or use a MIDI-to-USB cable to plug into your computer.

4. TURN ON YOUR SYNTH
If you are using a Macchiato Mini Synth, set it for short attack, long
release, and a deep LFO. If you are using a different synth, set its receive channel to 1 or Omni.
(By default, the Altura MkII transmits on Channel 1. You will learn how to change this shortly.)
5. TURN ON YOUR ALTURA MkII
Press the red power button on the back of the Altura. If you
built a card stock case, be careful how you squeeze your theremin; you don’t want to crush the
cabinet. The display will do a little dance, then show “
C 1
“, indicating the C Major scale. More
on key and scale in a moment.
6. WAVE YOUR RIGHT HAND
The right sensor selects the pitch to transmit to your synth. As you
wave your hand, you should hear notes coming out of your synth! The sensor is sensitive: hold
