Incredible.

Incredible app, love the optigan so much, i think optigan.com actually introduced me to this beautiful instrument.
Also, an error that I realized with the “Gay 90’s Waltz” disc, according to an actual picture of the disc it has 2 red flashers on it, one on the downbeat and on the 4th beat. Also, if you try and play Mr Wilson manually, for some reason when you enter the vamp loop section, the 5th switch turns downwards.

Classic sounds! It’s just so awesome!

One of my favorite apps. Still #1 in 2023! I mean 2024!!

Great App, Needs Update

Love how you’ve captured and recreated such a unique musical time capsule, but this app is 4+ years old and still on version 1.0 and that’s why this will have to be a 3-star review. I’m using an M1 iPad Pro with an external MIDI controller. The amount of stuck/phantom keys makes this unusable as anything other than a short-lived toy. I suggest: * Updating codebase to use AudioKit Engine, likely fixing any latency/stuck key issues * Adding toggle to allow app to run in background. Would love to play the app with my controller while playing from one of the many free PDFs you’ve made available, all on one iPad * Allowing app to be loaded as an AudioUnit Extension. Current InterApp Audio functionality is broken in Garageband and I’d love to be able to sequence these patterns with more control than what’s offered in-app * Updating app to include newly released sound packs as additional paid purchases * Providing clarification for the chord identification methods. The video on your site provides little to no help. You’ve got something really unique and special here. Consider showing it the continued love it deserves.

This is a truly amazing app

I don’t usually leave reviews, but I can’t believe how awesome this app is. If you’ve ever wanted an Optigan, please just do yourself a huge favor and get this. As a live musician and home recording obsessive who is always looking for new ideas, great crackly analog sounds and beats - this is a literal dream come true. I may get an iPad just to experience this app on a larger scale. That’s how great it is. Thanks, Pea and team! 🎹

Good, but…

E major plays the sample for D Diminished instead? It’s weird. The weirdest part is that it isn’t swapped. D Diminished still plays what it’s supposed to. PLSFIX!
