Noatikl III is here!
It's fully accessible and has its own soundfont player. Additionally, it has, get this, modular synthesis capability, which means you make one thing and connect it to another, like a circuit. You can do all kinds of wonderful synthy stuff with this app.
It's going to take me at least three foll length podcasts just to teach you to use it, or you can of course teach yourself. With all the accessibility hurtles surmounted, this thing's powerful!
have finally managed to put a podcast of this app together. It is here: https://audioboom.com/boos/4933010-noatikl-3-podcast-1
This app was completely redesigned with the blind in mind. It is 100% accessible, even the modular cents panel as I said before. Definitely worth the 10 bucks!
Thanks for the podcast; I'd already purchased this app, but hadn't quite managed to figure it out. I'll give it another go sometime soon. I noticed the double-tapping issue you mentioned, and found that split tapping is an alternative way of getting it to work. Also: I just bought Liptikl, the creative writing/cut-up generating app from the same developer. I haven't tested it extensively by any means, but from a brief look around the app it appears to be accessible. Have you tried Mixtikl and Wotja? If so, would you recommend them for someone who already has Noatikl? What are the differences between those three apps?
