Elastic OSC is a synthesizer app based on the DSP code of the Mutable Instruments Plaits hardware oscillator module, one of the most beloved (and cloned) oscillator modules in the Eurorack modular scene! Like the original, Elastic OSC comes with a wide variety of possible sounds, from analog-style, FM, and additive sounds to physical modeling, percussive, and even drum sounds. Elastic OSC can be used in both monophonic and 8-voice polyphonic modes. You can play the app using the (on-screen) keyboard or an external keyboard or sequencer inside your DAW of choice. The app focuses on ease of use, featuring two XY pads for intuitive sound manipulation of the OSC engine and the effects. Despite the simplicity of the cleaned-up interface, the sound possibilities are vast – thanks to 24 different oscillator models and the ability to automate parameter changes, as it is possible in all Elastic apps released so far. A versatile Arpeggiator makes it easy to start with simple ideas or can already create entire sonic worlds. Elastic OSC includes an integrated help system (tap “?”) to provide explanations for nearly every GUI element, the underlying DSP model, and most of the app’s functionality. CDM: "Elastic OSC becomes a must on iOS. It’s fun to use as an instrument in your iPad DAW of choice." SYNTH ANATOMY: "Takes the Mutable Instruments (Plaits) algorithms on a wild trip. A nearly perfect app." ROBERT LIPPOK: "Elastic OSC is incredibly fun to work with from the very first minute. The GUI is really well thought out and has 24 integrated synthesis models, as well as the ability to load DX7 sound banks. Omg, so good." --- FEATURES --- SYNTHESIZER – 24 different Sound Engines from MI Plaits DSP code – 4 main parameters per synth engine (Frequency, Harmonics, Morph, Harmo) – Recordable Modulations/Automations for almost all Parameters with a length of 1, 2 or 4 beats. – ADSR Envelope for Amplifier – LPG Envelope for Modulations of Timbre, FM, Harmonics – Adjustable Velocity effect on Volume and/or LPG Modulation – DX7 Bank and Wavetable Import ARPEGGIATOR With different Arp Modes, Rates, Octave Ranges and Skip Notes functionality MASTER FX – 5 effects (5 different Overdrive/Distortions, Hi-Low-Filter, Chorus/Flanger, Delay, Reverb) – Automations for all effects parameters – Master Gain and switchable Limiter effect SYNTH ENGINES - Virtual Analog - Waveshaping - 2 OP FM - Granular Formant - Additive - Wavetable - Chords - Speech - Granular Cloud - Filtered Noise - Particle Noise - String Model - Modal Resonator - Bass Drum - Snare Drum - Hi-Hat - Virt.

LFO MODULATION TARGETS • Frequency Amount • Timbre Amount • Morph Amount • Harmonics Amount • Filter Amount • Pan Amount LFO MIX The MIX view enables you to blend multiple LFOs and define how strongly each active LFO influences a target parameter. The closer a target is placed to an LFO corner, the stronger its influence. All active LFOs always sum up to 100% (e.g. LFO1 50%, LFO2 30%, LFO3 20%).

About

Wobulator

This audio effect plugin provides a stereo chorus with a unique "wobble" feature for a less predictable modulation. It can be used standalone or within compatible music production applications.

Highlights
  • Stereo chorus/modulation effect
  • Adjustable delay time (10-100ms)
  • Variable modulation rate (0.01-2.00Hz)
  • "Wobble" parameter for unpredictable modulation
  • Adjustable dry/wet mix
  • AUv3 compatible plugin

Wobulator Modulator Plugin (AUv3) Wobulator is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview Wobulator is a stereo chorus / modulation effect with a wobbly twist! The chorus effect is typically achieved by modulating the time of a delayed version of the dry signal, and mixing the two. Typically, these delay times are very short, around 20ms. Wobulator includes a "Wobble" parameter that adds variation to both the rate and depth, which makes the modulation cycle less obvious to the listener. Parameters Active - Toggles the effect On or Off. Delay - Varies the base delay time between 10-100ms. Higher delay times can be used to create ADT (automatic double tracking) type effects. Rate - Sets the base modulation LFO frequency between 0.01 and 2.00Hz. Depth - Sets the amount of base delay modulation. For example, a 50ms Delay, with 50% Depth, will be modulated between 25 and 50ms. Wobble - Sets the amount of variation introduced by an internal wobulation matrix! At extreme settings the unpredictable nature of the resulting modulation can sound almost tape-like. When Wobble is set to zero, Wobulator behaves like a standard chorus effect. Mix - Sets the balance between the dry / input signal and the wet / processed sound. At 50%, the mix is an equal amount of dry and wet. At 100%, you hear the wet / processed sound only, which is good for wobbly tape effects! If the name sounds familiar, Wobulator is an updated version of the WOBULATER module developed for Voltage Modular by Waverley Instruments.

Verdict

The call

The clearest difference is price: Wobulator at $1.99 against Elastic OSC's $17.99. Wobulator also leads on in-app purchases (none vs 2) and update cadence (every 2 days vs fortnightly). Elastic OSC's advantage is ratings volume (39 vs 6). On ads, monetization model, device support and iOS requirement there is nothing between them.
