About & Pics
ARPIO is a new musical instrument designed to play arpeggios*. Move up-and-down the matrix to set the arpeggio's speed, or left-and-right to set its pitch. Tilt the device for accelerometer-controlled volume and pitchbend, or shake for vibrato.
You may be interested in ARPIO if you play piano, guitar, violin, drums, synthesizer, arpeggiators, cello, or bass. Also, if you use digital audio workstations like Ableton Live, Bitwig Studio, Logic Pro, Fruity Loops, or Pro Tools.
In the future, MIDI support may be added depending on interest. This would turn ARPIO into a MIDI arpeggiator, allowing you to control hardware synthesizers like those made by Moog, Roland, Korg, Dave Smith Instruments, Elektron, Arturia, Yamaha, and others.
A similar version of ARPIO is available on iOS devices, under the name Arpeggionome.
*An arpeggio is a musical technique where notes in a chord are played in sequence, rather than ringing out simultaneously.
