AutoArp

Andrew Milloy
NEW: AutoArp is now FREE, with a fixed set of chords. Full functionality can be unlocked via an in-app purchase (at the lowest price tier). This means you can try it now and hear the results for yourself!

AutoArp turns your iPhone (or iPod Touch) into a musical instrument that is halfway between a traditional auto-harp zither and an arpeggiated analogue-style synth. Select a chord and strum the laser "strings" with your fingers to create a retro, and yet futuristic, backing to your music.

The synth engine features:
• square, pulse and sawtooth waveforms,
• attack and release envelope controls,
• a resonant low pass filter with cutoff and resonance controls,
• monophonic or polyphonic playback
• tremolo effect with LFO frequency and depth
• simple Echo effect

Up to 12 chords can be selected per 'song' and configured onto the playing buttons, allowing you to switch quickly between songs to load a new set of chords. Alternative bass notes can also be set for each chord. Currently there are major, minor, dominant 7th/9th/13th, minor 7th/11th, minor 6th, major 7th, sus4, 7#9 and diminished chord types in all keys, but more types will be added in future version updates!

Playback response is best on latest generation devices such as iPhone 4.
