Viking Synth is an authentic emulation of a classic monophonic analog synthesizer. It has three continuously variable wave oscillators, two ladder filters with a Dual Lowpass or Highpass/Lowpass configuration, a multi-wave LFO, and two modulation busses. Viking Synth uses state of the art DSP technology to accurately reproduce the sound of the hardware. You get a desktop quality plug-in at an iOS friendly price.

Viking Synth is an Audio Unit Extension Instrument (AUv3) that works as a plug-in inside host apps. Just open up your favorite host that supports Audio Unit Instruments and select it from the list of available Audio Units. Compatible with GarageBand, Cubasis, Auria, BeatMaker, AudioBus, AUM, Modstep, and more.

The user interface of Viking Synth is designed for quick and intuitive control. Knobs and sliders expand during tweaking and are designed so the current value isn't hidden below your finger. The six pages divide the synth into logical sections that can be accessed quickly. The filter display acts as an XY pad for controlling cutoff and resonance. Simply double tap a knob or slider to reset it to its default value.

Viking Synth comes with 178 presets in the categories Bass, Bright Lead, Electro Bass, FX, Percussive Lead, and Soft Lead. The synth excels at thick bass and rich lead sounds. The 50 Electro Bass presets were designed by renowned sound designer eXode. Presets work perfectly with GarageBand, Cubasis, and AUM.

At the heart of Viking are three adjustable wave oscillators. The continuously variable waveform knob gives the oscillators a unique sound that can’t be achieved with the fixed waveforms found in most synths. A noise oscillator provides three types of noise, one specifically modeled after the hardware.

Two modulation busses and an LFO provide flexible modulation capabilities. All of the options hidden deep in menus on the hardware are immediately accessible with one tap.

The filters are classic transistor ladder filters modeled meticulously. Two DSP varieties are available allowing for either reduced CPU load or soft clipping plus three additional overdriven modes. The number of poles is adjustable for a wider range of filter sounds.

Compare Viking to other synths:
– Viking’s oscillators are free running, not sampled, wavetable based, or generated from a zero point
– Viking’s oscillators use advanced techniques to avoid aliasing
– Viking’s oscillators have instability, which is controllable through the tuning drift control
– Viking’s nonlinear filter uses circuit modeling and provides soft clipping

One of the best iOS synths!

First off, the two idiots below need to read the app description before buying/complaining. YOU NEED A DAW THAT SUPPORTS AU PLUGIN HOSTING! This is not a standalone app and presets do work if you have one of the more competent iOS DAWs/AU hosts. I use Viking synth on my iPhone 6 hosted in AUM and midi sequenced with SunVox and it's an incredible synth! It really does have that nice warm analog sound and I've made so many amazing presets from scratch to use in my industrial techno productions. You can achieve a ridiculous range of sound using this lil plugin and using the XY filter in a live jam setting is an absolute blast. 10/10 would buy again 😬

The app just does NOT give a signal to be able to be used for Garageband.

I said what i said, period, it’s been 6 months since the last update, this needs to be fixed.

This isn't a stand alone synth!!!

Before you buy this an try launching it as a stand alone, it isn't a stand alone, you'll just see the manual. You'll need to use it with an app that supports Audi Units, like Cubasis, AUM or Auria Pro, etc. as for the synth itself, it's a great synth, but I suggest get the developers other apps to add fx, which is very reasonable imo. I won't go into detail about features since you can read them in the app description, but it does have a lot of great things to offer. The only thing I wish it had was polyphony, which would really make this a must have. I like what's going with this company and iOS music apps, audio unit support is the new frontier and developers need to start implementing it in their iOS music apps.

Edit: ok, I’m removing a star because when I’m using it in Beatmaker 3 or GarageBand I can’t access the presets. Sometimes I don’t want to start from scratch to get a sound, I want to save my presets and access them from any DAW that host audio units, not just some.

Developer Response ,

In fact, GarageBand does support presets. It works very well with them.
