Helps you approach creative creation with different work flows

This app is fantastic you can quickly begin to generate something inspirational and add hone to find something by exploring. The depths of the app are there to discover and explore at your own speed and need but is not a bar to making and creating with little or no musical or synthesis knowledge. The multiple creative workflows mean that you have many ways to generate projects and don’t fall into one grove.

Wonderful and inspiring the app is a piece of art unto itself.

Best app for generative music, nothing compares.

Update in april 15th
Totally stoked, they have integrated the graphic pattern editor. This makes it a breeze to create patterns. This app is now really complete and includes all the great features from all the past programs they have created. Thx a lot :-))

Wotja is unequalled for generative music software. The way the tracks interacts in a way which makes musical sense isn’t found anywhere else. They are the expert in the field, learning from their past, from Koan, Mixtikl, Noatikl...
To really get the most out, you have to spend the time learning it, neverless just putting a random “jam” on can sometime sound better than anything else.
What do I wish for in the app? A graphic pattern editor like they had in Koan.
The ability to run it on an ipad and have the midi out to any of your hardware synth is ultra cool.

Thank you so much for your kind words and detailed review. Yes, Wotja is a deep app and does reward time spent learning how to use it. However, as you say, you can use let it auto-generate and get great results, too! We hope you enjoy how we continue to evolve Wotja. Best wishes, Intermorphic

The Best Generative Composer for iPad Keeps Getting Better

I’ve been composing with Intermorphic products for years, going way back to Koan and Noatikl. They just keep expanding on the capabilities of the software. It’s a joy to create with these tools.

You can simply let the software do all the work or you can dig deep into very detailed controls. So much to discover...
