SHREDDER for iPhone - Synth for Guitar

By Yonac Inc.

Open iTunes to buy and download apps.


Introducing SHREDDER, the first professional iOS synthesizer built for your guitar: now custom designed for your iPhone and iPod Touch.

You control SHREDDER with your guitar. Simply plug in, hit the Guitar Synth button and start jamming. No special synth pickup needed: our revolutionary guitar tracking algorithms convert your guitar notes into synth notes.

SHREDDER's true analog-modeling synth engine is the culmination of our vast expertise on Digital Signal Processing on the iOS platform. With luscious dual-oscillator sound generators, custom designed 4-pole multi-mode resonant filter, dedicated FM envelope, dual dedicated LFOs, you are invited to tweak and relive the vibes of any decade of electrified music.

All the basic controls you need live or in the studio are grouped conveniently on the Main Panel. You can use the Guitar Mix fader to blend in your guitar with the SHREDDER synth, use the Gate Attack and Release knobs to find the "sweet spot" for guitar tracking.

Connect to SHREDDER with USB or in-jack guitar adapters compatible with your device, or even use the device's built-in mic as an input.

But SHREDDER doesn't just toot its own horn: It's also a MIDI interface for your guitar. You can use it to control other compatible virtual MIDI apps, MIDI devices, or even computer programs by just playing your guitar. With output that can simultaneously cover all the 16 MIDI channels and an easy to use in-app MIDI destination browser, you can start driving your favorite apps, synths, or drum machines right away.

Impossibly makes me sound better!

...meaning usually I don't sound very good, but this guitar synth is packed with so many fx and options, I'm running out of excuses. Haven't messed w/midi controls yet, but just using it to tweak my playing into outer space puts a grin on my face everytime! It's a lil' glitchy with the sound from time to time, and I'm okay with that-- always room for improvements. But as it is, it works great for my purposes... now, if you'll excuse me, I've got an album to make on this iPod Touch :)

oh heck yeah. sooo worth it.

It does everything. sounds strange, but very smooth for an app. eventually you will want this app. i've paid for tons of apps and this one is a great buy. built in tuner, cool presets, background audio + plus multitasking for playing along to that good ol' funkbox app. yet to tweek it fully and i already love it. so great.


I got this because it was on sale and the UI looked cool. I do not even own a guitar. Normally, impulsive purchases like this are meh, but in this case BANG ZOOM I was incredibly impressed. You don't need a guitar. Shredder acts like a hyper vocoder using your voice or ambient sounds. GET IT RIGHT NOW.
