## What is bent.fm lite?

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!

### 3/5 — It’s funny and good, but…

*2024-01-14, version 3.8*

So I am really into circuit bending, and I love listening to circuit bent toys on YouTube. However, I cannot seem to use this app properly because it is not voice over friendly and I wish that you could add a feature where you can import your own audio files and then pitch bend and make other weird sound with this application because that would make it even better.

### 4/5 — I love it

*2023-05-28*

It’s super fun to mess with. That being said: the only problem I have is that the sounds do not play through Bluetooth headphones when they are connected. 

Before, when I had wired headphones, I had to unplug and replug them after starting the app in order for it to register the headphones as connected, and send the signal through them. Unfortunately, I lost my old headphones; so I no longer have them as a backup and now only use Bluetooth (which does not connect, at least on the 2020 SE) I’d like to make weird technobabble noises without everyone else hearing what I’m doing. Please fix this issue.

### 2/5 — Once fun app, now silent.

*2021-08-23*

Works sporadically if it all on the latest iPadOS

### 5/5 — This is one of my favorite noise making apps.

*2020-12-30*

I’m a circuit bender hobbyist, and this app is the closest thing that you’re ever going to find to an actual circuit bent keyboard.  So much glitching and noise!  I wish there was a VST like this for my PC DAW.   I use this app a lot with Garageband, which is kind of my “hobby-fun, music maker, idea maker” for when I’m on the go.  This app is free, and there are no annoying adds.  And the sounds are amazing.  You never know what you’re going ti get out of it.  It’s a serious, “happy accident” generator.

### 5/5 — Great fun!!!

*2019-06-18*

Hope y’all can make some more of point towards the coding for this synth!

It’s cool to create a series of patches than play the sounds into delays/cassette decks. Good intuitive noise machine, feels inspiring to use.

### 5/5 — GEM

*2018-08-21*

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.

### 5/5 — What a weird sound

*2016-10-25*

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

And it's fixed for iPhone 7!!!

### 1/5 — BUMMER

*2016-05-28*

Used this app a lot but now it's not working after upgrading to iPhone 6s.
No help from the developer either. 😥😥😥😥

### 5/5 — Dirty fun

*2016-04-24*

If you enjoy the sound of circuit bent instruments, you will enjoy this. Have circuit bent, used modulars, and early digital hardware to explore these sounds in the past. No need to do that anymore. Though I upgraded to the deeper version, I still use bent.fm lite often. Thank you to the developers.

### 1/5 — NO SOUND

*2016-03-18*

Also getting no sound whatsoever from this app, but evidently the developer is unconcerned.
