bent.fm is a full FM model of a circuit-bent synthesizer. bent.fm allows the user to tweak classic circuit bending modifications like fine and octave-decimated clock bends, and experiment with more esoteric bends. Circuit-bent distortions and algorithmic sequences can be created by (im)proper connections on the bend matrix. Reroute digital serial information through the base chip set (a numerically controlled oscillator) and extra logic gates (NAND and XOR, binary counters), and experience architecture-level bit crushing. For anyone interested in circuit bending, glitch sounds, industrial music, and post-procedural art.

PLEASE NOTE: On the iPhone version, bent.fm only allows control of one of the oscillators due to space constraints. If you do not have an iPad, please get bent.fm lite instead, it's free!
On the iPad version, bent.fm lets you re-route connections between both the oscillators.

Audiobus and IAA supported!

Mr. Cropper

After some exhaustive App Store perusing for experimental music apps I stumbled upon this gem. Now I don’t have to bend my sk1 again and again... get this app folks of the fervently musical.

What a weird sound

Hang 2

I don't know how he made the circuit bent sounds but they are on point!

And it's fixed for iPhone 7!!!

Doesn’t always work


Sometimes I start the app and get no sound out of it. Good to play around with, but maybe has a bug or two.
