Still growing and still amazing software

I’ve use Wotja and its earlier incarnations of Noatikl/Mixtikl since I have had my first iPad. There really is nothing quite like it for composing music. Whether its generative ambient soundscapes, classical compositions, modal Jazz or you name it, this is a great tool to get things fleshed out. The interface is fairly spartan and the learning curve is steep but well worth it. In earlier versions, my advice was always, get used to the MIDI routing, turn off the sounds and drive other instruments with it (which still works) but now with AUv3 hosting, you can finally do all of your composing and instrument arrangement within Wotja. Why is that so important? If you’ve tried combining MIDI, AUs and concurrently running apps on iOS you probably know how crash prone all of that can be. Even with state of the art iPads with M1 chips, the software just isn’t as bullet-proof as desktops provide. The ability to use all of Wotja’s features with your favorite synths hosted by just Wotja is really a game-changer. The developers are very active on the product and despite some stability jitters, Wotja is really becoming a full-featured composition tool.

Been a bit since I went deep into Wotja, so many amazing new features and easier ways to do it. So many improvements in the interface. I have so many hardware boxes, like octatrack, pyramid, ndlr… when it comes to create generative music which is not just random stuff, nothing comes even close to Wotja. You can be musical with it, and shape the flow of the river… Still the Rolls in that field.

I Like Wotja!

I use it on my macbook and ipad, it’s a lot of fun. Wotja gets remarkably better every update… and for software with like 30 years of history that’s crazy. Anyway if you’re into making or hearing generative music, or just want to make music in a unique way, I recommend Wotja.
