Fettkraft vs VAPolyLoop

Fettkraft spreads out low and lower-midrange harmonics in time. It is designed specifically for sources with pronounced transients, such as percussive, plucked, or rapidly decaying sounds. Powered by an ultra-strong dispersion modeling algorithm, Fettkraft delivers high levels of acoustic dispersion in a single, efficient instance – completely eliminating the need to stack multiple plugins or wrestle with the messy side effects typical of stacked all-pass filter-based dispersers. Acoustic dispersion can transform your tracks in several ways: • Novel Harmonic Interaction: Feed time-separated harmonics into saturation or heavy dynamics processors to uncover entirely new acoustic textures • Perceptual Low-End Depth: Get more powerful "oomphs" without boosting frequencies or increasing loudness. Fettkraft makes your low end feel deeper, thicker, and more sustained • Headroom Recovery: Unstack overlapping transient energy to lower instantaneous peak levels. Depending on your source material's phase composition, this can free up valuable headroom FEATURES: • Powerful dispersion for the low end and lower midrange • Near-ideal phase shifting with a flat frequency response • Completely transparent mid and high frequencies • Preserves RMS / loudness (± 0.1 dB) • Delivers pristine transients and has zero latency – a massive advantage over spectral delays • Despite its strength, it remains free of the rhythm disruptions that typically arise from extreme sub-bass phase delays inherent to traditional low-latency dispersers • Tuned to avoid the "raygun" effect found in other dispersion algorithms, to ensure versatility across diverse sounds and genres TECHNICAL NOTES: • Bass portamento / pitch bend effects are not recommended when using this plugin; uninterrupted bent notes crossing operational frequency boundaries can cause phantom beats • The efficacy of headroom recovery depends on the source material. E.g. some synthetic inputs or optimized / pre-processed ones may even experience peak level increases (while RMS is preserved) PLEASE NOTE: • An AUv3-compatible host is required to use this app • Supported sampling rates: 44.1, 48, 96 kHz

VAPolyLoop features lowpass filter and amplifier which are optimized for playing by step sequencer. VAPolyLoop contains polyphonic synthesizer and analog style step sequencer. The synthesizer consists of three oscillators, resonant low pass filter, amplifier, distortion effect and five LFO. VAPolyLoop operates as a stand alone or as an AudioUnit Extension (AUv3) for iPhone, iPad and Mac. Stand Alone supports Ableton Link, MIDI and audio file export. Built-in Effects include delay, chorus, flanger, reverb, eq and compressor. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. Main Features Polyphonic Synthesizer. Lowpass filter modeled on diode ladder filter. Distortion Effects Analog style step sequencer. Maximum 8 voice polyphony. it depends on performance of the device it is running. Built-in effects and piano roll sequencer. Audio Export. Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) Support Audio Unit Extension (AUv3). Support MIDI 2.0. Support Foot Pedal and Per Note Control. Support Ableton Link, Bluetooth MIDI, MIDI In / Out. Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. Full Factory Preset: 96, Effect: 40 Improvements Support MIDI Foot Pedal (CC#11, CC#64) MIDI CC Settings are saved. It will be recovered when the app launched in the next time. UI Color can be selected from black, navy or gray. System Requirements iOS 17.0 or later Devices with Apple Silicon are recommended. A13 Fusion or above is highly recommended. if sound is distorted when using a device with less CPU power, reduce number of voices. AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension. AudioUnit Extension is supported by Apple Logic and Apple Garage Band on iOS and macOS. For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension.
