PhaseRings is a musical instrument for performing expressive music with touch gestures. Anyone can create a beautiful piece of music with our sound schemes and generative composition engine! Each ring on the screen represents a different pitch, and you can tap and swirl on each ring to create combinations of long and short notes. The angle and size of your tap will change the timbre of the notes you create! New in version 3.0, PhaseRings is also an AUv3 Audio Unit plugin. Load it as an instrument in hosts like AUM, GarageBand, Logic Pro for iPad, and Cubasis — play the rings inside your host, run several instances at once, drive it from MIDI tracks, and record it through your host's effects. PhaseRings includes seven expressive "sound schemes" featuring percussive sounds like marimba and singing bowls as well as pure synth sounds like phase and string synthesis. Four "compositions" of pitches are included in the app, but you can also create your own custom composition by choosing three base notes and scales. PhaseRings will do the rest, generating a series of great setups from the harmony you choose! Features: - AUv3 Audio Unit instrument for AUM, GarageBand, Logic Pro, Cubasis, and other hosts - 7 sound schemes - 4 built-in compositions - Custom generative composition - 11 scales and modes - Core MIDI in and out for iOS MIDI accessories and MIDI-enabled apps - VoiceOver support and light/dark appearance

Here is the secret behind every great drum: the professionals build them in layers. A kick is a sub, a click, and a body. A snare is a tone, a crack, and a wash of noise. The traditional way means juggling samples, plugins, and routing to pull it off. Bruno makes that professional technique effortless. Bruno is built around three ideas: • Four synthesis engines per drum, layered in parallel, each with its own complete signal chain • Six voice types that reconfigure all four engines for the right frequency range • Intelligent randomization and a context-aware tweak system The result is punchy kicks, cracking snares, shimmering metal, evolving percussion and twangy plucks. Whether it is your first drum synth or your fortieth, Bruno meets you where you are. Hit the dice for an instant new sound. Roll a single engine or nudge one tab at a time. Or dive deep into per-engine sound design when you are ready. SIX VOICE TYPES • Kick, Snare, Hat, Clap, Tom, and Pluck • Each voice retunes all four engines for its own frequency range and parameters • Parameter values are preserved when you switch voices, so happy accidents carry across • String-model Pluck with pickup comb, stiffness, and modal resonance FOUR INDEPENDENT ENGINES • Analog, FM, Fold, and Resonant, summed in parallel • Every engine has its own tune, decay, and volume plus pitch envelopes • Filters: 8 types with cutoff, resonance, bipolar envelope, and decay • Three LFOs per engine: Cutoff, Pitch, and Character, with sync, gate, phase, and range • Per-engine compressor, drive with 4 saturation types, delay with 4 types, and 3-band EQ • Per-Engine noise, includes independently controlled noise decay, with white, pink and crackle noise. • ON and OFF per engine, so a drum can be one engine or a dense four-layer stack SHAPE THE TRANSIENT • Dedicated Vol Env tab with click amount, click tone, decay curve, and tail • Per-engine Body Peak EQ for tuned resonance and thump • Voice-specific controls like Kick Tick, Snare BP wires, and Pluck stiffness and hum MASTER FX BUS • Saturator, Compressor, Transient Shaper, Reverb, Stereo width, and Limiter • Global 3-band EQ with quick presets • Copy to All across filter, compressor, delay, EQ, and every LFO INTELLIGENT RANDOMIZATION • Musical preset generator tuned per voice for usable drums, not noise • Generate by style and target by category for each of the six voices • Roll a whole preset, a single engine, or one tab at a time • Tweak system for subtle, context-aware variations • 100-entry history you can step forward and back through • One-tap dice for instant inspiration SAMPLE EXPORT • Export Any Sound – Turn your Bruno creations into reusable audio samples. • Single-Sample Export – Quickly export drums, percussion and other non-chromatic sounds as individual samples. • Chromatic Multisample Export – Automatically create complete multisample sets from pitched sounds. • Flexible Multisample Mapping – Choose the root note, octave range, and semitone spacing for your multisample exports. • Flexible Audio Export – Choose sample rate, bit depth, and mono or stereo format to suit your app or hardware. • Instant App Export – Send Bruno sounds directly into Koala or Loopy Pro with no editing required. • Build Your Own Sample Libraries – Export sounds for hardware samplers, drum machines, DAWs and grooveboxes to create custom kits and multisample instruments. EFFORTLESS WORKFLOW • Consistent layout across all four engines • Live scope with per-engine spectrum feedback • Per-tab hints explaining the controls plus production tips BUILT FOR REAL MUSIC • Factory presets including curated Signature sounds • Preset import and export • Master Preset import and export • Deep MIDI: full Note and CC mapping (CC mapping AUv3 only) • Clock-synced LFOs lock to host tempo • AUv3 plugin that works in AUM, Loopy Pro, Drambo, Logic Pro, GarageBand, Cubasis, and more
