## What is FXComposer?

FX Composer is a multi-effect. It includes the protocol Inter-App Audio.

FX Composer includes these effects :
- noise gate
- compressor / expander
- fuzz / distortion
- multimode filter (LPF, BPF, HPF)
- chorus / flanger
- delay
- reverb (short and long hall reverbs)
- EQ : bass and trebles definition.

We did the synthesizer called «Dazibao», and we wanted to create an innovative multi-effect using the new concepts of this polyphonic synthesizer. We choose to implement four new kind of interfaces and programming concepts to this unit : you can use these effects as a casual one using the «single effect» mode, or you can create sequences of effects synchronized to the BPM of the host, or pads XY of four effects, or layers controlled by the input level, or also a keyboard of effects with a programmable time transition.

These four modes will help you to imagine new directions in the field of the sound design we guess! With few actions, you'll be able to create the most unbelievable effects very quickly and easily!

You can use FX Composer to enhance the audio input of your iPad, or use the Inter-App Audio protocol to add a powerful multi-effect to your set. In this case, the BPM of FXComposer is automatically synchronized to the host.

Enjoy it!

Tested using an iPad with an A7 processor, GarageBand with several music synthesizers and audio inputs for IAA

### 4/5 — Works just fine. Pretty basic fx but needs mayhem effects

*2018-12-31, version 1.2*

The effects are usable. It’s on the more tame fm side until you use multiple ones with extreme settings. Cheers mate, and maybe some more drastic pitch shifting or synth type effects for the next update.

### 3/5 — how do i use this app?

*2015-04-16, version 1.0*

squealing when launched. turn the input down and noisegate up... im confused how to use this app to sequence effects?

### 1/5 — Horrible Constant Clipping

*2015-03-23, version 1.0*

Please provide me a refund. I have both an IPad Air and IPad 2, I get nothing but clipping no matter how I am using it.

Thank you,

V/R

### 1/5 — Clipping

*2015-03-18, version 1.0*

This app won't run through anything because it seems to be eating up the cpu. I either get silence or crackling at best. In cubasis on an iPad  3, inter app audio delivers only silence and routed alone through several different synths, I hear nothing but hardcore clipping.Can I have my money back, please. Good idea but it's still too much for the iPad to handle, yet.
