something unexpected will happen. You will have to route the Altura through software to redirect 
this control number, or avoid touching this knob when in Pitch Bend function.

Turn the DATA NEAR knob to display numbers 

0 - 127

. This changes the size of the Neutral 

Zone that separates the Bend Up zone from the Bend Down zone.  On startup, the Altura 
defaults to Function 1: Pitch Bend, and the neutral zone will default based on the physical 
position of the DATA NEAR knob. At 127, you will find a large piece of air where the pitch 
remains unaffected. Change it to zero and the neutral zone will essentially disappear: you will 
find it difficult to return a bent note to its original pitch, except by simply removing your left hand. 
When using the Altura in Pitch Bend mode, set the neutral zone to whatever value suits your 
need.

You will find the Altura lacks the resolution to use the Pitch Bend to produce precise, subtle 
vibrato effects characteristic of the original theremin. Use the Modulation effect for this instead.

FUNCTION 2: MODULATION

Function 2 emulates the behavior of the Mod Wheel on a conventional MIDI controller. It 
transmits a value from 0 – 127, as determined by the left sensor, to Control #2 on the currently 
selected Send channel.

Turn DATA FAR all the way left to display 0. Turn DATA NEAR all the way right to display 127. 
Move your hand near, the number rises, and you should hear note modulation, usually a tremolo 
effect. Move your hand far away, the number falls, and the effect diminishes. You can reverse the 
effect by swapping the numbers. The controller acts like a mid-air slider: move your hand to the 
desired value; remove it and the value will “stick”. This behavior is the same across Functions 2 – 
6. Note that changing the Data knob values will have no effect until you wave your hand in front 
of the left sensor. Only this will trigger transmission of a MIDI message.

On the Macchiato Mini Synth, Modulation controls the Depth of the Low Frequency Oscillator 
(LFO). (You won’t hear any effect if the Rate knob is set to Minimum!) Touching the Depth 
knob on the Macchiato will override the Altura. Using the Altura will override the knob on the 
Macchiato.

FUNCTION 3: NOTE-ON VELOCITY

This function emulates the role of key velocity on a conventional keyboard. The Altura reads 
values 0 – 127 as determined by the left sensor, and combines this with pitch data from the right 
sensor. Whenever the Altura detects it is time to transmit a new Note On message, it combines 
the current velocity value with the current Pitch value into a single Note On message transmitted 
on the currently selected Send channel. The Note On velocity defaults to 127 upon startup of the 
Altura. Use the DATA NEAR and FAR knobs to set a maximum and minimum value for velocity. 
(Keeping a minimum velocity around 30 will prevent you from accidentally silencing your Altura!) 
You won’t actually hear an effect until you wave your hands in front of both sensors.
