GranSample
iOS Universel / Musique
GranSample is a music creation tool where sample meets granular — a 16-pad sampler fused with a granular synthesis engine, designed for iPhone and iPad.
KEY FEATURES
16 Touch Pads
An intuitive 4x4 pad grid with velocity-sensitive triggering and real-time waveform previews. Each pad has independent volume, pan, sample loading, and color customization.
Advanced Granular Synthesis Engine
Fine-tune grain position, size, density, pitch, spray, stereo spread, and window shape (Hanning, Gaussian, Triangle, Trapezoid). Up to 128 simultaneous grains for rich, evolving textures.
Full Effects Chain
Each pad and the master bus support up to 8 reorderable effects: Reverb, Delay, Distortion, EQ, Compressor, Chorus, and Filter — all adjustable in real time.
16-Step Sequencer
Program beat patterns for each pad with per-step velocity control, synced to an adjustable metronome.
Sample Editor
Full waveform display with grain region overlay, real-time preview playback, and intuitive knob controls for all granular parameters.
Recording
Built-in microphone recorder captures up to 60 seconds of custom samples. Master output recording exports your performances as WAV or M4A files.
Mixer
Independent volume and pan faders with Mute/Solo for complete mix control.
Presets & Projects
Save and load granular parameter presets. Manage full projects in JSON format to continue your creative sessions anytime.
16 Factory Samples
Includes drums (Kick, Snare, Hi-Hat, Shaker), melodic instruments (Piano, Rhodes, Guitar, Synth Pad), and textures (Rain, Singing Bowl, Vinyl Crackle, and more) — ready to play out of the box.
Pro-Grade Audio Engine
Built on AVAudioEngine with a lock-free, real-time safe architecture. Hermite interpolation for pitch shifting. Zero-allocation render thread ensures minimal latency and maximum quality.
