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

Classic vibrato and chorus effect. The app is Audio Unit AUv3. With the “blend” slider you can gradually make it from pure vibrato to chorus by adding the original sound into the mix. Rate goes from really slow to space 12 Hz vibration sound. There is also a build-in reverb effect that is very useful if you use the app as a stand alone effect. Vibrato is an Audio Unit Effect AUV3 and can be used inside GarageBand or other AU host apps as an effect plug-in. When used as stand alone app, it is adding effect to the audio input so you can play your guitar, bass or synth directly through the app if you have the connector to do so. Vibrato controls: - Rate - that is the vibrato speed - Depth - this is how far the pitch is changed - blend / chorus - that is the volume of the original sound so you can make it from pure vibrato when on 0 to classic chorus - Reverb

Verdict
The clearest difference is rating: Viking Synth at 4.7 against Vibrato's 3.5. Viking Synth also leads on review sentiment (70% vs 33%) and update cadence (every 4 months vs every 20 months). Vibrato's advantage is price ($1.99 vs $3.99) and iOS requirement (10.0 vs 12.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
