New symmetry feature added

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

My favorite music player

I listen and watch this app make music. I find this more enjoyable than a music service simply because it can shuffle the many moods and generates unlimited music. Each song being different and never the same. I use this more than any other music app, including my music subscription services!! I don’t make music with it, I just listen and let it come up with its own things. Simply amazing. Between this and reflection I have more ambient music than my iTunes library! Ha!

Amazing generative music app!

Was uncertain since app hasn’t been updated in 3 years; however, it works fine on my iPad Pro with iOS 11. Having been a fan of Brian Eno in my youth, I enjoy creating and listening to these ethereal and calming tones. How to use: Draw several lines or dots with your finger, then wait for the song to develop; the music will follow the patterns you created. Also, the neon color flows and geometrics are beautiful to behold! Very relaxing and meditative, for those into this genre.

Pioneering Genius

When Eno makes an app. You better listen. It doesn’t get any better for generative music than this one.
