data? The tiny blue trim pot just above the OCTAvE NEAR knob is the Articulation Adjust pot. This 
little knob slows down or speeds up the right-sensor read rate. The Articulation value represents time 
between polling cycles: low values mean very fast polling; high values mean very slow polling.

You access this control using the “Easter Egg” principle:

a.  Turn off the Altura.
b.  Turn all seven control knobs to the far left.
c.  Turn on the Altura. The display may flash a series of numbers which represent the software 

version on your unit. When the display shows one number steadily, this represents the current 
Articulation setting. When we build units here in the Lab, we factory-preset Articulation to 32 
microseconds, which is pretty fast. This value seems best for quick response and good stability.

d.  For fast response at the expense of stability, turn the pot clockwise. The number will fall in 

increments of 15 microseconds.

e.  For increased stability at the expense of responsiveness, turn the pot counterclockwise. The 

number will rise in increments of 15 microseconds. At values around 60 or 75, you will be 
able to move your hand along the right sensor faster than the Altura can keep up. You will 
miss notes. When you remove your hand from the beam, the last note will linger before the 
Altura decides your hand is gone for good and terminates the note. This can be ideal if you 
play slow, languid melodies, and precise note selection is essential.

Articulation is a “set-it-forget-it” thing.

PROGRAMMING THE ALTURA THEREMIN MIDI CONTROLLER

The Altura software was developed in the Arduino integrated development environment (IDE). If you 
are an Arduino enthusiast, you can download the Altura open-source code from our github repository, 
edit it to your heart’s content, and upload, or “flash”, it to your Altura to make your own custom 
controller. Even if you know nothing about programming, and have no desire or intention to learn, the 
ISP header on your Altura’s PCB makes it super-simple to obtain software updates from Zeppelin Design 
Labs and flash them to your Altura.

The Altura Theremin MIDI Controller is covered by the Creative Commons Share Alike / Attribution 
/ Non-Commercial license. You are free to modify and redistribute the Altura software as long as 
you a) redistribute it under the same license as the original, b) give proper attribution to all previous 
contributors, and c) don’t try to sell your work without talking to us about it first.

We host the Altura source code and all supporting files on Github at

. Please go to the Altura repository page now and read the README.md file for 

detailed, current instructions on obtaining and modifying the Altura source code. Look for the section 
PROGRAMMING THE ALTURA.

We may publish updates from time to time. You may develop your own Altura mods and contribute 
them to our Github page for possible inclusion in future releases.
