Read full description

This is a AUv3 compatible audio effect which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand and NOT a standalone app. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels. The FilterMorph is one of our most fun, interesting, experimental and yet incredibly useful AUv3 plugins to date. It takes the concept of a traditional audio filter and pairs it with overdrive, bit crunching and tape delay to perform some incredibly neat real-time or beat synced automation effects. At the heart of the effect are a set of transitional filters (low pass, high pass, band pass, notch and formant filter) which you can assign to the Cutoff Control. The twist here is that you can assign different filters to each end of the frequency spectrum and morph between them to achieve a much more interesting results. So for example you can use a LP filter for low frequencies and a BP filter for high frequencies, and the frequency dial will smoothly transition between the two. The main interface of the effect scrolls to reveal a set of two finger touch-pads, each of which responds to one of more fingers. Each pad can be assigned two of several parameters, one to the vertical axis, and the other to the horizontal. This allows you to control up to 4 knobs in real-time using only two fingers. A glide control allows you to control the rate of change so you can create those gentle sweeps without the effort. But it doesn't stop there... we also include effects such as overdrive, bit shifter and tape delay and these parameters can also be freely assigned to the finger pads. A configurable modulation section also allows you to automate panning or vibrato and assign various envelope shapes. Hold multiple fingers down on a pad and the play cursor will fly between your fingers at a specified speed. Press the HOLD button and you can then release your fingers and have them playback a set pattern. Press the SYNC TO BEAT button and the play cursor will move from one point to another at set beat intervals. Use the FOLLOW feature to follow finger movements etc. The build in Tape Delay allows control over delay time, feedback and level, but the advantage of this type of delay is you get the warping pitch shifting effects as you change the delay time. This allows for some very interesting effects, especially when applied to strings or held chords. This is an essential tool for those wanting to add a creative or experimental twist to any form of electronic composition, adding a few extra dynamics into your mix with very little effort. This is one of a suite of AUv3 compatible plugins which will also soon be available from 4Pockets.

About

Ringotron

This app offers advanced control over ring modulation effects for sound design and audio processing. Its multi-band design allows precise manipulation of the audio spectrum, with a special soft mode to reduce unwanted intermodulation. It can also function as a resonant filter that smoothly transitions into a ring modulator.

Highlights
  • Parallel ring modulator units
  • Stereo separation control
  • Ultra-narrow band resonance
  • Ribbon controls for frequencies
  • Modulation system for band centers
  • Tempo syncing for oscillators
  • Soft limiter and clipper

Read full description

Ringotron allows taming the strong transformational effects of traditional ring modulation, opening up a wider range of possibilities in sound design and audio FX. Its multi-band design enables fine control over which parts of the spectrum will be transformed by the effect. A special soft mode is available that borrows concepts from feedback modeling, which can be used to reduce intermodulation effects that are often a limiting factor in the more general applicability of ring modulators. In addition to the layers of control they provide, combination of these core features also allows the plugin to act as a stereo, multi-peak resonant filter that can also smoothly morph into a ring modulator. FEATURES: • 2 parallel ring modulator units (max. modulator frequency: 8 kHz) • Stereo separation can be added to band center, mod. frequency, mod. phase • Ultra-narrow bands can be used to create highly resonant sounds • 4 large ribbon controls for band center and modulator frequencies • Band center frequencies can be modulated by the built-in modulation system • Tempo syncing can be independently configured for each oscillator • Built-in soft limiter and clipper to protect against volume spikes IMPORTANT INFORMATION: The plugin comes with a zero-latency, non-brickwall soft limiter, and as such, its stopping power is limited. Make sure to always leave enough headroom or use an external brickwall limiter for total protection against powerful transients. Alternatively, a built-in soft clipper is also available. PLEASE NOTE: • AUv3-compatible host app is required • Suported sampling rates: 44.1, 48, 96 kHz
