FUNCTION 6: X-Y MODE

This function causes the right sensor to emulate the left sensor: it no longer sends Note On 
messages. It sends control change messages of your choosing, just like the left sensor. You 
would use this mode not to create melodies, but to shape the sound already being produced by 
a synthesizer. A typical use would be to assign two different filter sweeps to the left and right 
sensors, or a filter sweep to one and resonance to the other.

With FUNCTION knob set to 6, the DATA FAR and NEAR knobs serve to set the limiting MIDI 
values produced by the left sensor. The OCTAvE FAR and NEAR knobs do the same for the right 
sensor. In this mode, key signature has no meaning, so use the KEY knob to select the Control 
Change Number (CC#) for the left sensor, 0 – 127, and use the SCALE knob to select the right-
sensor CC#. On startup, these default to CC# 85 & 86, which are undefined. Your synth may 
respond immediately to many of the standard MIDI-defined controllers. See your synthesizer’s 
documentation for a table of available CC’s. By using one of the many undefined CC#’s, you 
can route the Altura through performance software and redirect the data any way you wish, 
assigning it to any function.

For the right sensor to perform its best in X-Y mode, the Articulation must be set to a very low 
value, like 0 or 15. See “Articulation Adjust” on page 22.

FUNCTION 7: CHANNEL SELECT

Turn the DATA FAR knob to set the channel on which the Altura sends MIDI messages. Only 
devices downstream set to the same channel will respond to the Altura. This lets you daisy-chain 
scads of devices without ever using control software. Old school!! The Altura defaults to Channel 
1 on startup.
