Read full description

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.

Flux Liquid Audio is a real time multi-effects processor and sequencer designed to be used as an AUv3 plugin within your favourite DAW such as Cubasis, NanoStudio, BM3, AUM etc. The plugin allows you to create patterns containing multiple effects which are triggered on beat boundaries. Patterns can be contuously looped or you can chain multiple patterns into a song. The advantage of this is that you can for instance add a delay to a particular vocal phrase rather than have a continuous delay effect on the entire vocal. You could add varying harmonies using the pitch effect or create gated stutter effects on specific parts of a string section. A pattern can be 16 to 64 beats in length and can be run at one of two speeds, standard or fast which is great for gate type effects. You can create up to 24 patterns which can be automated in any order along with your host DAW's beat position. An effect is added using nodes. A 'node' is layed on the timeline over one or more beats, each node has its own unique settings. The node divisions control varying aspects of the effects such as number of repeats, delay time, modulation speed etc. all perfectly synced to the beat using the node division buttons. There are 11 effects in total, Filter, Repeat, Gate, Pan, Delay, Pitch, Tape Stop, Reverb, Bit Cruncher, Reverse and Flanger, all of which can be used at the same time. Effects Descriptions: The filter effect allows LP, HP, BandPass and Notch filters which have definable cutoff, resonance and modulation amount. Turn the modulation up to max to start generating random cutoff and resonance values. The Repeat function was specifically designed for beat synced sources such as drum machines, allowing sections of the previous sub-beats to be repeated at varying speeds and lengths. The Gate effect can be used to create holes in the sound and generate stutter patterns or fades. This effect allows definable attack and release for each individual node. Pan allows automated panning at varying speeds, but you get to mix different panning modes and speeds at each step of the pattern. Delay is a beat synced delay which allows you to create multiple delays with varying delay times within the same pattern allowing some nice cascading effects that are not possible from a single delay alone. Pitch allows you to add independant left and right channel pitch shifting of up to +/- 12 semitones. 'Harmony' mode allows you to add vocal harmonies at specific sections of a song, while 'Glide' mode allows you to gradually transition from the current pitch to another. Tape Stop is a great addition allowing you to simulate a tape recorder stopping and starting, as well as some interesting scratch, warble, bounce and elastic effects. Bit Cruncher is a great for dirtying up specific drum hits by downsampling the audio. Flanger allows you to create subtle chorus/Celeste or heavy flanging effects which can be re-triggered or free running. Reverse is great for creating shadow notes on drum patterns by reversing the last section of audio. Reverb allows some interesting gate reverb type effects on specific sections of audio. The node divisions let you modulate the reverb trail for some interesting ambient effects. Features: ○11 great real time effects. ○Low CPU usage. ○Modulated LP, HP, BP and Notch Filters. ○Gate and Repeat effects. ○Regional Pan and Delay effects. ○Tape simulator effects. ○Mix multiple effects within a single pattern. ○Add harmonies to targetted sections of vocals. ○Patterns up to 64 beats in length. ○Create up to 24 patterns. ○256 steps per song.

Verdict

The call

The clearest difference is price: Flux at $9.99 against ShockWave's $19.99. Flux also leads on update cadence (every 9 days vs every 2 months) and iOS requirement (13 vs 15.6). ShockWave's advantage is rating (4.6 vs 4.0) and ratings volume (188 vs 17). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

ShockWave costs $19.99 and Flux $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

ShockWave holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: ShockWave has 188 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 55% of ShockWave's written reviews are positive against 62% of Flux's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ShockWave ships an update every 2 months, Flux every 9 days. Both last shipped on November 6, 2026.
