Ribbons is an extraordinarily fun and expressive musical instrument for iPad.

Inspired by early electronic instruments such as the Ondes Martenot and the Theremin, Ribbons (formerly "Ondes") emulates the fluid playing style of those classic instruments with an interface and synthesis engine firmly grounded in the present day.

Whether you’re gliding through melodies & chord changes or creating dense polyphonic sci-fi soundscapes, Ribbons is an instrument unlike any you’ve played before.

A “desert island” app if there ever was one

It's a niche product, but a good one


I've felt conflicted about how I feel regarding Ondes. I didn't buy it immediately, but definitely kept my eye on it from Day One. Even now that I own it, I'm not exactly sure how to use it in my music. But if you watch some of the demos and like what you see and hear, I feel like it is a 5-star app with a unique interface and resulting sound.

The "slider" interface is very attractive looking, but it's not really an "innovation" for this app. ThumbJam, Bebot, Figure, SynthX, and on and on have all used some variation of this control scheme, which works great on an iPad. Unfortunately, MIDI out control is not in the works at this time, but perhaps in the future.

So the usefulness of Ondes will mostly depend on its unique internal sounds. I will say that the presets don't offer a huge array of variety, but there is a synthesis engine within your app, which is what differs it from something like ThumbJam, which is sample-based. So you make your own sounds. Really liked the slider controls and variation of "snap to" as you cross over note lines. You can have a meandering almost sci-fi sounding pitch, or snappier transitions that land on the exact note. It's a beautifully put-together app with some unique sounds, and I value it as much for its originality as the end "usefulness". I would not want this as my primary instrument app, but as an add-on for unique leads and cool atmospheric stuff, it's great.

Couldn't be happier


This is my favorite instrument app by far. The only competition it has in quality are Animoog, tc, and Orphion, and really anyone interested in using the iPad as a musical instrument should have all off them. I like them all, but find myself drawn more and more to the sound and simplicity of ondes as well as the intuitive controls over the excellent sounding filters and effects. This is what a mature ipad musical app should be and with the new update, swarm oscillators and midi functionality this is the yardstick of quality going forward.
