This is the Optigan for iOS. The Optigan, short for Optical Organ, was a chord organ from the early 1970’s. It is remembered today for its unique system of sound reproduction using optical discs. These LP-sized film discs were optically encoded with 57 concentric tracks, which contained loops of musical combos playing chord patterns in different styles. Each disc contained a specific style of music (Bossa Nova, Big Band etc) which the user could control by pressing the chord buttons. Changing the discs was as simple as putting a new record on your turntable. Think of it as the 1971 version of GarageBand. Despite this novel technology, the scratchy sound of the Optigan left a lot to be desired. The iOptigan we present here truthfully recreates that lo-fi sound. 25 of the original 40 discs are included, the remaining 15 can be purchased individually or all together in the Complete Pak. Specifications and Features: • Disc loading rigth-side-up or upside-down • Spring Reverb (virtual) • Optical Metronome • Audio Demo for each Disc • MIDI in/out • MIDI chord detection • MIDI File Import • Sequencer with Record and Playback • Sharing for songs as Audio and MIDI File • iTunes File Sharing • Inter-App Audio • Smart background audio • Help overlay • Headphone optimised stereo (optional) • Radio Mode for Chord Buttons or Keyboard • Comfortable speed control in semitones or BPM
