This Spectral Processing Workstation lets you craft evolving, non-linear filter shapes and movements impossible to achieve with analogue EQs. Multi-Curve Spectral Filtering MagicFilter is a multi-curve spectral filter and EQ workstation designed for detailed, creative frequency shaping. Apply independent filter amounts per frequency or frequency range, then mix, modulate, and spread your curves to create anything from subtle, organic movement to extreme spectral transformations. Beyond Conventional EQ Unlike analogue or traditional digital EQs, MagicFilter operates in the frequency domain, enabling filter curves and dynamics that would be impossible with hardware. Design non-linear, highly customized shapes and introduce dynamic movement through modulation. Morph seamlessly between four different filter curves, and use the Curve Modifier to shift, invert, or skew them — even in stereo — for precise and flexible control over spectral motion. Global Controls & Fine Shaping Quickly adjust cut and boost amounts to refine your overall curve, and use the built-in lowpass and highpass filters to set the tonal boundaries of your sound. Fine-tune the balance using wet gain and dry/wet control, enabling anything from subtle enhancement to bold, transformative filtering. These controls ensure fast, intuitive workflow while offering deep flexibility. MagicFilter is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX). More information here: https://gs-dsp.com/products

VAPolyMk3 is a multi synthesis polyphonic synthesizer for iPhone, iPad and Mac. Inspired by the last generation of classic analog synthesizers in the late 1980’s such as Oberheim Matrix series synthesizers, It offers Subtractive Synthesis and modular FM Synthesis. It operates as a stand alone or as an AudioUnit Extension (AUv3). Stand Alone supports Ableton Link, MIDI and audio file export. Oscillator Section features 3 Oscillators and 3 Modulation Oscillators. Each Oscillator has envelope and amplifier. Oscillators can be routed for Subtractive Synthesis and FM Synthesis. Signal from Oscillators are routed to mixer, resonant low pass filter, resonant hight pass filter and amplifier. The synthesizer also features two ADSR envelopes per voice, two LFO and analog style sequencer. Built-in Effects include delay, chorus, flanger, reverb, eq and compressor. VAPolyMk3 also includes sequencer which features piano roll editor and parameter automation. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. Main Features 3 oscillators and 3 modulation oscillators can be routed for Subtractive Synthesis and FM Synthesis. Analog Style CV Sequencer. Maximum 8 voice polyphony. it depends on performance of the device it is running. Built-in effects and sequencer. Support MIDI 2.0. Support Foot Pedal (CC#11, CC#64) and Per Note Control. Support Audio Unit Extension (AUv3) Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. Audio Export. Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) Support Ableton Link, Bluetooth MIDI, MIDI In / Out. Option to turn off anti-aliasing for devices with less CPU power. Include 271 Factory Presets. System Requirements iOS 17.0 or later This app requires a lot of CPU power. Devices with Apple Silicon or equivalent A series chip are recommended. A13 Fusion or above is highly recommended. If sound is distorted when using a device with less CPU power, turn Anti-Aliasing-Option off or 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.
