Instead, breath pressure and valve movement on the brass instrument are read by an embedded Arduino microcontroller<span class="Apple-converted-space">&nbsp; </span>and sent to a laptop, where the data is mapped onto various parameters in synthesis software; the resulting electronic sound is returned to the trumpet, where it plays through a loudspeaker inside the bell, and is further processed acoustically by valve position (changes in the length of tubing filter the speaker output), movement of a plunger mute (wah-wah style filtering), and orientation of the instrument in space (panning).</p> ER -
