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.

Read full description

ShimmerVerb combines a massively lustrous reverb with parallel pitch shifters to add ethereal layers making any signal, well, "shimmer." Oftentimes, producers would achieve the effect by using Eventide pitch shifting hardware such as the H910, H949, or H3000 or other rack mount units in combination with a reverb. This production technique was popularized by Daniel Lanois and Brian Eno on U2's The Unforgettable Fire. Now, this iconic sound has been refined and extended with a modern, unified interface that is great for adding dreamy ambiance to guitars, keys, synths, samples, and vocals. In typical Eventide fashion, features have been added such as the ability to infinitely feedback the signal, resulting in cascading reverbs that smear into oblivion. Feedback can be further fine-tuned by specifying which frequencies are fed back through the low/mid/high cross-over network. ShimmerVerb shines via its playable, performance-based parameters. "The Ribbon" is an easy to program performance macro allowing users to morph between two settings with one control. Desktop users can plug in a MIDI keyboard and gain tactile command over this function via the modulation wheel. Ribbon mappings are great for Feedback swells, moving the Pitch knobs, or changing the Size for a massive detuning result. ShimmerVerb also boasts a HotSwitch for calling up another state of parameters inside the same preset. Use this for changing octaves, turning off/on the pitch shifters, or simply turning the Mix up or down while crafting your performance. Finally, the Freeze button allows you to make smeared textures out of single voices, full pads, or percussive elements resulting in metallic "shimmers." Features: - Unique reverb plug-in with parallel pitch shifters on the reverb tail. - Easily pitch with perfect fourths, fifths, and octaves. - Micropitch tuning available around perfect intervals. - Four octaves of pitch shifting (from two octaves down to two octaves up). - Delay pitched signals up to one second or sync them to your DAW's tempo. - Feedback determines how much delayed signal is fed back into the input of the reverb. - Low, Mid, and High cross-over network determines which frequencies are fed back. - FREEZE holds the current state of the reverb in a smeared texture. - The RIBBON allows for real-time modification of several parameters at once. - HOTSWITCH allows for instant switching between two sets of parameters within one preset. - Available as an Audio Units AUv3 plug-in and Standalone App.

Verdict

The call

ShockWave and ShimmerVerb both sit at 4.6 stars, but that hides the real split: 78% of ShimmerVerb's written reviews are positive against 53% of ShockWave's. ShimmerVerb also leads on price ($14.99 vs $19.99) and iOS requirement (11.0 vs 15.6). ShockWave's advantage is ratings volume (190 vs 12). On rating, update cadence, ads and in-app purchases there is nothing between them.
