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%).

Oscidia is an AUv3 plugin for iOS which can be loaded into your favorite DAW allowing you to use it as a sound source for any MIDI source. Its wide range of features and oscillator types allow it to produce a vast variety of sounds. In particular, the inclusion of WaveTable greatly expands the traditional wave types and brings a wealth of modulation options. Oscidia has 3 oscillators per voice, and each oscillator can be a different wavetable – all working and morphing together to create some incredibly amazing sounds. Oscidia includes SINE, SAW, SQUARE, TRIANGLE, SUPERSAW, SUPERSQUARE, WAVETABLE and ADDITIVE wave types. You can import and export compatible wavetables using drag and drop directly to the WaveTable manager. Wavetables support morphing and warping (phase distortion), all controlled by the Mod Matrix routing. The SINE and TRIANGLE wave types both support several wave folding modes which allow dramatic real-time morphing too. Oscidia also supports 5 filter types which support 12/24dB modes and morphable LP/BP/HP filter modes which can be automated from the Mod Matrix or via the Sequencer. The sequencer itself is very unique and allows up to 3 simultaneous ARPs to play at the same time. Each ARP can directly control the 3 oscillator levels independently per step, as well as the pitch, filter morph, cutoff frequency, probability, gate, note repeat and ties. This allows for some really complex rhythms to be created that are not tied to pitch. Oscidia Features: • 3 Oscillators Per Voice. • Support for Wavetable and Additive synthesis. • WaveTable supports Morph and Warp (Phase Distortion) features. • 4 LFOs Per Voice. • 5 Filter types with 12/24-bit slopes and morphable LP/BP/HP. • 4 ADSR (Attack, Decay, Sustain, Release ) or FEG (Fluid Envelope Generators). • Wave Folding is available for basic waveforms such as SINE and TRIANGLE. • OSC Sync. • XMod & Ring Mod (on osc1 & osc2). • Additive Synthesis for glass, metallic and bell like tones. • Build in Sequencer (with 3 independent ARPs). • Mod Matrix. • MPE Mode. • Internal Effects - reverb, delay, chorus, Haas, and Phaser effects. • Drag and Drop for import and export presets and wavetables. • Build in Help Manual.

Verdict
The clearest difference is in-app purchases: Oscidia at none against Elastic OSC's 2. Oscidia also leads on rating (5.0 vs 4.7) and price ($14.99 vs $17.99). Elastic OSC's advantage is update cadence (fortnightly vs every 6 weeks) and ratings volume (39 vs 12). On review sentiment, ads, monetization model and device support there is nothing between them.

Elastic OSC costs $17.99 and Oscidia $14.99 up front. Elastic OSC sells 2 one-off in-app purchases. Oscidia asks for nothing beyond the download.
Oscidia holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 39 and 12 respectively. Written reviews complicate that: 92% of Elastic OSC's written reviews are positive against 88% of Oscidia's, so the app with the better star average is not the one people write more warmly about.
Elastic OSC ships an update fortnightly, Oscidia every 6 weeks. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
