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.

Sometimes the unexpected is cool!

I bought this app out of curiosity and it turns out I find it really cool. Sure it’s cheesy as hell and it sounds old (with crackles and all other noises associated with vinyls) but that’s what makes it charm. You imagine what all of these sounds from yesteryears could bring to your music today and then the possibilities are infinite. Buy it!

iOptigan is perfect

I've been using this since day one and love everything about it! I especially like the variable tempo. Before this app came along, I was using an Optigan emulator made by another company. While it was good, this is way better. Fans of the band Sparklehorse will find some instantly recognizable sounds here. Please don't ever stop supporting this app!
