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

Great to listen to

This app is great to listen to, but like others have mentioned, lacks the control, or feeling of control that bloom had. I love the sounds. Nice work guys!

Is the glitchy sound intentional?

I've been using Trope for a few days, and agree with other reviewers about the disappointing lack of user control compared to Bloom, but I do like the ability to "draw" music by dragging out the notes/sounds.

However, I have noticed that when playing Trope, my iPhone creates a static-like glitchy noise at the beginning of each note, especially short, single touch operations.

While I sometimes like glitches in my electronic music, this aspect of Trope seems out of place, assuming it is deliberate, as it is too "samey". Has anyone else noticed this?

Not as good as Bloom

This certainly has its merits - the ability to drag notes out and the graphics are an interesting representation of the sonic outcome. However, I would have preferred to have had more control over the parameters in terms of response and the generative function. It all seems a little too impressionistic, whereas in the case of Bloom the user had greater control of the process. Additionally, I really wish Eno would make some more visually pleasing video graphics as opposed to his current output which resembles a series of badly composed Power Point transitions.
