As an AUv3, it unlocks dual-layer sampling for blending sounds with independent tuning and effects, including parametric EQ, dynamic filters (Low-Pass, High-Pass, etc.), reverb, delay, chorus, flanger, phaser, and compressor—all automatable for precise sound design. MIDI handling with customizable note ranges and real-time control makes it essential for layering textures or automating mixes in your host app. Core Features • Dual-Layer Sampling: Mix two independent oscillators with Octave, Semitone, Cents, Pan, and Level adjustments for rich, multi-dimensional sounds. • High-Fidelity Oscillators: Precision-engineered for versatile textures across genres, from warm analogs to crisp digital waves. • Advanced Filters & EQ: Sculpt your tone with five filter types (Low-Pass, High-Pass, Band-Pass, Low-Shelf, High-Shelf) featuring Cutoff and Resonance, plus Parametric EQ for Gain, Q, and Center Frequency tweaks. • Professional Effects Chain: Enhance with Reverb (High/Low Decay, Reflections), Delay (Feedback, Time), Compressor (Threshold, Attack), Chorus (Voices, Depth), Flanger (Delay, Feedback), Phaser (Poles, Center Freq), and Peak Limiter—all automatable in AUv3 mode. • Creative Chord Pads: Five pads per layer with Strumming modes (Normal, Up, Down, etc.), Rate, Delay, and an iCloud-synced Chord Library for instant harmony building. • MIDI Mastery: Dual 8-octave keyboards per layer, Key Zone sliders for custom ranges, and full MIDI compatibility for controllers—ideal for live performance or studio integration. • Flexible Export & Sharing: Output in WAV, AIFF, CAF, M4A, or MIDI (.mid) formats, with seamless DAW compatibility via AUv3 or InterApp-Audio. Tools for Creativity • Expansive Sound Library: 1,100 premium samples in 11 categories (Bass, Chords, Drums, Guitars, Leads, Pads, Orchestral, and more), expandable with unlimited .ids presets. • Streamlined SoundBanks: Effortlessly browse categories, instruments, or user presets; swipe-select sounds and save setups instantly. • Chord Editing Suite: Customize via on-screen keyboards, fine-tune Strumming, Rate/Delay, and use Copy/Paste, Repeat, Reset, or Clean for melodic experimentation. • Preset & Chord Management: Local/iCloud storage with rename/delete via swipe; AUv3 presets persist across sessions for workflow efficiency. • MIDI Recording: Capture ideas as .mid files for easy import into other apps or DAWs. • Custom Metronome: Adjustable BPM and signatures (e.g., 4/4, 3/4) with quick RESET to defaults. • Real-Time Monitoring: Track sound details, bank info, RAM, and CPU usage for optimized performance. • Pitch & Time Tools: Scale pitch without time distortion and lock peaks for creative effects. • Enhanced Connectivity: Supports AudioShare, MIDI controllers, and AUv3 hosts for a fluid production ecosystem. iDousyn is more than a synth—it's your mobile creative hub, blending accessibility for beginners with depth for pros. Its sleek design, vast library, and AUv3-enhanced features like automated effects and layered synthesis unlock boundless possibilities, whether you're jamming solo or producing in a full DAW setup.
