## What is Viking Synth?

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.

Presets
Viking Synth comes with 228 presets in the categories Bass, Bright Lead, Electro Bass, FX, Percussive Lead, Soft Lead, and Synthwave. The synth excels at thick bass and rich lead sounds. The 50 Electro Bass and 50 Synthwave presets were designed by renowned sound designer eXode. Presets work perfectly with GarageBand, Cubasis, and AUM.

Oscillators
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.

Modulation
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.

Filters
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

### 5/5 — Rocks My Amadeus

*2025-05-15, version 1.2.0*

I fell in love with this little synth app on day one of it’s release!  Did anyone else notice how it’s a Moog Voyager in disguise?  The frequency split does some really cool stereo-affecty-deeliohoo that trips with my mind.  Of course, I paid for it! Now that it unbelievably FREE you’re insane if you have yet to add it to your arsenal of sound making kit. It works flawlessly, has a small footprint, and when using multiple instances in Cubasis, GarageBand, Logic Pro, LoopyPro, etc. you can produce a fully polished composition from kick to sizzle, it’s brilliant.  Now GO MAKE SOME NOISE!  :-)

### 4/5 — Free AUv3 plugin Mono Synth

*2024-10-03, version 1.2.0*

Great value as free. Presets and other options work in GarageBand but not in Drambo.

### 2/5 — Looks fantastic but can’t use :/

*2024-07-15, version 1.2.0*

Just doesn’t show up anywhere on garageband on my iphone. Very sad…

### 3/5 — Viking Synth won’t show up in GarageBand

*2024-03-04*

I can’t see the Audiounit from Viking synth in GarageBand, every other audio unit from your team is working. I got an iPhone SE(2020) so I don’t think my phone is the problem. Please help if you can. Will only rate 3 stars, because your other audiounit apps are good, will change it to 5 if you can help me

### 2/5 — Great sound, problems with presets

*2024-01-12, version 1.1.0*

Using this in GarageBand version 2.3.15 on my iPad Pro iOS 17.1.2

This app is frustrating because it sounds awesome and the presets are amazing, but for some reason the presets only show up maybe 10% of the time I start a new track. The other 90% of the time it just says “default” or “preset” but when I click on it there’s just an empty window where the preset library should be. Sometimes the presets will work on a track but when I click back in to choose a new one they mysteriously disappear. It’s too bad because I really want to use this app but the inconsistency of the preset library is making it untenable for use. 

Devs do you have any advice? I’ve deleted and reinstalled, powered on and off: still having the same issue.

### 5/5 — Glad to see the auv3 first adopters still giving us presets after all this time !

*2024-01-08, version 1.1.0*

Kudos would love to see something new I definitely would support!

### 5/5 — Viking

*2024-01-08, version 1.1.0*

It ain’t pretty, but it’s functional.

### 3/5 — Doesn’t show up anymore

*2023-08-12, version 1.0.8*

Downloaded this today and it’s not showing up in the AUv3 menu on Garageband… dunno what happened.

### 5/5 — Can Anyone say Voyager?

*2023-04-20*

Tell me this is not modeled on the Moog Voyager.  The filter is CRAZY, sound splitting awesome sauce!  

Long live Viking Synth!

I've used it on every device since iPhone five through to my 14 Pro ...nearly a decade of use and it still kicks a**!

### 5/5 — Good light synth

*2023-01-02*

Awesome for basic synth sounds.. very light on cpu.
