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
Negative Harmony
Read full descriptionHide full description
Negative Harmony lets you explore one of music theory's most fascinating transformations: reflecting any chord or progression across a tonal axis to produce its harmonic mirror image. TAP ANY CHORD Select a root and quality on the interactive Circle of Fifths. See the original chord and its negative simultaneously, with voice-leading automatically applied. BUILD PROGRESSIONS Add chords to a progression and play them back — originals or negatives — with smooth voice leading between every chord. Common tones are held, not re-attacked. UNDERSTAND THE THEORY Built-in theory section explains the concept from first principles: the axis, the transformation formula, voice leading, and the history from Hugo Riemann to Jacob Collier. 5 SOUNDS Choose from Rhodes, Strings, Choir, Organ, or Synth Pad — the same high-quality soundfont used by professional music apps. MULTILINGUAL Full support for English, Spanish, French, German, Italian, and Portuguese.
