ShockWave is a monophonic Synthesizer designed to bring modular style workflow to the world of iOS & AUv3 plugins. Built around the concept of Phase Distortion (PD) Synthesis, Shockwave includes a pair of PD Oscillators each capable of creating everything from pure Sine Waves over smooth Sawtooth and Square Waves to Resonance & Sync sweeps, filtered Noise and more. In addition to the Synth Voice, ShockWave includes a dedicated control section housing a pair of 8 step sequencers, a sample & hold module as well modules for trigger divisions, logic comparisons and controlled randomness. A pair of Low Frequency Oscillators and 2 Attack/Sustain/Release (ASR) Envelopes serve as main modulation sources and can be used in a number of ways. Envelopes can be triggered from a number of internal sources including other modules such as trigger divider, logic or chance module but can also be connected to each other allowing for a wide range of patches usually only possible in large modular systems. LFOs are individually tempo sync-able and capable of producing total of 5 different waveforms each. The two sequencers can run independently or combine to one 16 step sequence where rate and length can be controlled independently for each of the two. In true modular nature almost any control within ShockWave can be modulated with up to 11 sources - simultaneously. Modulations are setup simply by holding a control and dialling in the desired amount in a list of all available sources. A special X-Ray mode adds a realtime display of all currently active modulations right at their corresponding control making it easy to understand what's happening inside the synthesizer at any given time. Synth Voice and Control Section are accompanied by built-in Delay and Reverb sections placed on send busses with all of their controls including the send levels being available as mod destinations. Last but not least, ShockWave features a solid MIDI implementation including support for, aftertouch, velocity, wheels, custom CC mappings and up to 4 dimensions of expression when using MPE compatible controllers, such as the Roli Seaboard, Linnstrument, Geoshred, KB-1 and others. MIDI Output is supported as well and includes Note and Control Change output generated from various internal sources including Sequencers, Envelopes and LFOs making it possible to control external MIDI gear or chain multiple plugin instances for advanced, self driving patches.

TESTERE is a 7-oscillator supersaw synth where each voice stacks 7 saws with per-voice control over detune, phase, waveshape (flavor), stereo pan, and a sine wave sub oscillator. Instead of micromanaging each oscillator manually, TESTERE uses distribution curves to control these offsets. You dial in a curve shape and a spread amount, and the synth applies the resulting values across all oscillators smoothly interpolated, musically controllable, and repeatable. This system allows for infinite combinations, from tight analog-like stacks to wide, animated swarms, all with a minimal set of parameters. Each oscillator is a wavetable oscillator with a selection of saw waveforms. You can subtly vary the shape across oscillators or push it further for complex harmonic shifts. All detune, phase, flavor, and panning spreads are curve-driven and musically scaled, making the synth flexible but not overwhelming. A clean sine sub oscillator is included for adding low-end weight, with an adjustable octave (set in settings) and a level control (in the FX panel). Features: - 7-saw stacked oscillators per voice, 8-voice polyphony - Curve-based detune, phase, flavor, and pan spread - Clean sine sub oscillator with octave and level controls - Single global LFO with assignable target - Analog-style ladder filter with rise/fall envelope - ADSR amp envelope per voice - Built-in arpeggiator - Stereo ping-pong delay - AUv3 plugin support AUv3 Compatible Hosts: Works as a plugin in GarageBand, Logic Pro for iPad, AUM, Loopy Pro, Cubasis, BeatMaker 3, and other AUv3-compatible hosts. Whether you want to dial in tight classic stacks or explore chaotic layered textures, TESTERE’s curve system gives you deep control without micromanagement.

Verdict
The clearest difference is review sentiment: Testere Supersaw Synth AUv3 at 100% against ShockWave's 53%. Testere Supersaw Synth AUv3 also leads on price ($7.99 vs $19.99) and update cadence (every 4 days vs every 2 months). ShockWave's advantage is ratings volume (190 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
ShockWave costs $19.99 and Testere Supersaw Synth AUv3 $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Testere Supersaw Synth AUv3 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ShockWave has 190 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 53% of ShockWave's written reviews are positive against 100% of Testere Supersaw Synth AUv3's.
ShockWave ships an update every 2 months, Testere Supersaw Synth AUv3 every 4 days. Both last shipped on September 21, 2026.
