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.

SYNTHWAVER: SOUND IN MOTION Step inside the sound. SYNTHWAVER is a spatial synthesizer for iPhone and iPad that turns pure tones, noise, frequency modulation, and movement into an instrument you can feel around you. Every voice travels through a three-dimensional orbit, giving drones and atmospheres a sense of direction and depth. Put on headphones, press play, and hear synthesis leave the flat plane. BUILD A WORLD, ONE VOICE AT A TIME Start with one synth, then add more to create layers of pitch, color, rhythm, and space. Each voice has its own frequency, level, orbit speed, tilt, noise, FM, and reverb. Let one tone circle slowly beneath a fast-moving signal. Blend a warm noise bed behind a cluster of pitches. Set every layer in motion, or hold movement still and focus on timbre. Complex spatial scenes stay approachable because every sound remains visible, independent, and immediately playable. SCULPT PITCH BY EAR OR BY NOTE Explore the audible range from 20 Hz to 20 kHz with a responsive frequency control. Use the one-octave keyboard for familiar notes, then shift across ten octave positions to reach the register you need. Indicators identify voices at a glance, while numerical readouts keep precise tuning close. Whether you are building intervals, beating tones, low-end rumbles, or glassy highs, pitch never feels buried in a menu. MAKE EVERY SOUND MOVE Movement is part of the synthesis engine. Set each voice to orbit from near stillness to 6.8 revolutions per second, then tilt its path through the Z-plane. High-quality HRTF headphone rendering creates a binaural field with changing position. Layer speeds and angles until simple waveforms become kinetic patterns: circling, crossing, separating, and reconnecting in space. GO BEYOND THE SINE Turn on frequency modulation for sidebands, metallic edges, animated basses, bells, buzzes, and unstable textures. Dial in the modulation index, choose a frequency in hertz or a musical ratio tied to the carrier, then refine it with coarse and fine controls. FM can add subtle shimmer or push far into complex territory. Each voice has its own settings, so one layer can remain pure while another fractures into rich motion. BLEND TONE, NOISE, AND SPACE Move from a clean oscillator to noise, or settle anywhere between them. Shape noise continuously from white to pink, from bright hiss to softer ambience. Then place each voice in one of ten acoustic spaces, including rooms, halls, chambers, plate, and cathedral, and set the wet/dry balance. Orbit, noise color, FM, and reverb make SYNTHWAVER at home creating test tones, evolving drones, cinematic atmospheres, strange machines, and abstract sound art. FAST, TACTILE, AND READY TO EXPERIMENT SYNTHWAVER keeps essential controls on the surface. Start or stop voices, minimize them into frequency chips, bring any synth forward, and stop the scene instantly from the master bar. Shape individual levels or adjust overall output. The interface adapts to portrait and landscape on iPhone and iPad, so it stays playable whether you are exploring on the couch, sketching with headphones, or presenting an idea. SAVE THE MOMENT When a combination clicks, save it as a preset. SYNTHWAVER remembers every voice and its playing state, pitch, spatial motion, FM, volume, noise, octave, and reverb. Open a scene later, continue shaping it, or build a library of drones, studies, and sonic environments. Move from discovery to a sound you can revisit. FOR CURIOUS EARS SYNTHWAVER is for musicians, sound designers, composers, students, educators, spatial-audio enthusiasts, and curious listeners. Study frequency relationships, explore modulation, design moving textures, build meditative soundscapes, or lose yourself in a strange orbit of your own making. No timeline. No maze of pages. Just sound, motion, and direct control. Your headphones are not just the output. They are the listening space. Create a voice. Set it in motion. Shape the air. Enter SYNTHWAVER.
