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

Time for an update.

I agree with the reviewers comments about it's limitations. Feeling that its twenty-odd megabytes of iPhone memory that could be used for better things. I'd like to see a few of the ideas for improvements taken up by the developers.

Perfect work music

I poopoo-ed this app when I first bought it many years ago. The interaction element didn’t gel with me. Now that I’m working from home during the coronavirus lockdown, I’m finding it perfect for creating ambient mood music to help with focus. I just turn it, click Listen and the textures evolve by themselves.

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.
