Trope, designed by ambient pioneer Brian Eno and musician / software designer Peter Chilvers, expands further on the ideas introduced by Bloom, their acclaimed iPhone application.  Darker in tone, Trope immerses users in endlessly evolving soundscapes created by tracing abstract shapes onto the screen, varying the tone with each movement.

Recommended for headphones and external speakers.

"Trope is a different emotional experience from Bloom - more introspective, more atmospheric. It shows that generative music, as one of the newest forms of sonema, can draw on a broad palette of moods." - Brian Eno

Problem with update

Since updating I can only listen not create. Please could you address this?

Somewhat more weighty and textural than Bloom, I use this for background atmosphere, creative work, relaxation and travel. I find generative music absolutely fascinating and the guys who made this have done well. Beautiful.

Updated review

For some reason the App would update and was giving me errors about iOS 11 incompatible but a hard reset has now updated and it no longer complains

Developer Response ,

This is incorrect - Trope runs under 64 bit, and done so for some time. I suspect you are running an older version, please try updating or contact our support address and we'll sort out the issue.
