Shaper is a multi-fx processor that allows you to redefine or totally destroy any kind of source.

Shaper is perfect in any iOS music workflow:
- as stand alone app to process your outboard equipment
- as inter-app audio in Aubiobus or other compatible daw apps as AUM, Modstep, GarageBand, and so on
- Shaper is an Audio Unit Extension

Its clear, clean and minimal user interface lets you fall in love so fast with its potential, that after just few minutes of use you'll feel like it always been one of your favorite music production tools.
Its noise is your noise.

All you need to add a personal touch to your sounds is here. Emphasize your basslines working with waveshaper's sections blend and color, or increasing the clip's value (this works great also on drums and acoustic percussive sounds). Blow digital coldness to your synths going wild with S&M and Bits&Samps functions, or increasing wrap or fold values . Add unpredictable dynamic glitches thanks the exclusive gate.

Shaper is composed by several modules, that you can rearrange as you want:
- a glitch gate
- a waveshaper section with 5 brand new inspiring functions: Muffin, Multistress, Cracker, S&M, Bits&Samps
- a transform section with wave-clipper, wave-wrapper, wave-folder, and the new sFold function
- a resonator/short delay, that can act as a comb filter too

You choose how to feed it and how to mix it with a gain and a dry/wet section. Two oscilloscopes display audio signals before and after processing: this gives you a realtime visual feedback about how you are morphing your sound wave.

Each parameter offers a range that lets you process the signal so slightly... Or so massively! Changing the order of modules in the chain, makes of Shaper an incredibly versatile sounds processor!

The waveshaper module applies a shaping function to incoming signal. It's the timbral core of the audio process. Several functions are available: Muffin and Cracker applies a digital warming function with a distinction in the weight that noise takes in the wet signal. Multistress is a bit more fragmentes function, giving a more modulated FM-ish result. These three let user control the process via blend and color parameters. This helps you to apply a different dose of Shaper cure to your sound ;)

S&M is basically an amplitude modulation, driven by ramps; the length parameter here sets the frequency of these. This function brings a like-metal flavour… Raw digital power!

The last function Bits&Samps is a standard bit reducer.

Shaper lets you work fast with gestures support:
- you want to rearrange modules? Just drag them as you prefer and create different chains for different needs
- need instant reset to default value for a parameter? Just double tap on cursor
- fine tuning? Just tap and hold the cursor, then drag it left or right to increase the resolution of your vertical dragging

Shaper is Audiobus presets and state saving compatible. It can also store its status while working in all major host-apps sets as AUM, Modstep, GarageBand, etc. You can also save internal presets, and share them with your collaborators easily.

Still Great

I’ve had this for a couple years now & still use it regularly.
The dev’s description states the resonator works as a short delay and that the bits&samps option is a basic bit reducer. These 2 facets of this fx processor are the reasons for which I use it. The resonator/delay is great, not short, and gets me a delay that many “dub” effects can’t quite match.
The bit reducer is described as ‘basic’ by the dev but it is actually quite unique in its tone which sounds markedly different to my ears from anything else I’ve used - something I didn’t expect from what is a ‘basic’-type of effect.
The remaining controls shape & flavor your sound with plenty of room to color outside the lines and allow you to develop your own aural signature.

My favorite iOS distortion

If you were to only buy one iOS distortion, it should be this one. You can get all kinds of colors and distorted tones out of it as wet or as dry as you’d like. It blends well and can easily go into broken up glitchy amp past it’s breaking point territory if you'd like to go there. All then important parameters are automatable by cc.

Great with Modstep or others

Looked like what I wanted so took a chance and it is great. Does exactly what it says and is that extra sauce that you really can use in modstep. Let me qualify this: if you are using AUs in modstep like I am then creates very smooth experience (by giving you effortless audio destruction) ;)
