What’s New

Version 1.3

Complex chords support:
When editing chords, you can add 4th chord notes to your taste.

Audiobus integration:
Fortamento can now be configured as MIDI Sender in Audiobus.

Navigation between bars while in editing mode:
We've added arrow buttons on the top of the editing screen, so you don't need to jump between main and editing screens when editing multiple bars.

MIDI output "off" state:
In previous version, active MIDI session was displayed in bold font. This was confusing to many, so there's a dedicated "off" state now.

Fixed a bug when the first note would be slightly delayed.

Other minor algorithm improvements and bug fixes.

Tried all the rest, this is the best!

I have found this app particularly helpful when I land in a “progression rut” or just need a nudge in a different direction. Super clean UI holding a rather flexible set of configurable parameters, making it by far the most customizable AND easy to use generative app I’ve come across. Could use a bit more of a instrument selection although I have grown fond of the pads.
I probably haven’t done more than star and app in 2 years, but I feel compelled to shout out the dev for an awesome, well thought out and awesome tool. Thanx guise!

Hi Kitty,

Thank you for your feedback!

Just wanted to update you that we have a new version out with new sounds, MIDI out (so you can use your own instruments) and other useful features.

Midi out rules

Really nice UI that works well on my iPhone and the new MIDI out means this is about to get a lot more use from me. Only thing I can think to improve is being able to change the order of the four note sequence windows. Thanks to the dev for continuing to add features to this very affordable generative tool.

Great app

I am not a big reviewer even though I own lots of apps. This one is great and has given me lots of ideas for composition. I would ask more scales to work with but so far an amazing app. I don’t know any other that does the same thing like this one
