Stream Pro is Delta Sound Labs' first virtual instrument. The team brings modular hardware concepts to modern software design, building on the foundation of its Stream effects plugin with deeper granular control, keyboard playability, and spatial audio features.
The result is a flexible tool for turning any sound into a dynamic instrument, ambient texture, or animated 3D sonic environment. Start with a recorded instrument, vocal phrase, or field recording, then explore its tone, timing, and movement through granular synthesis.
Features
- Two Core Modes: Single for ambient textures, Multi for playable instruments
- Independent pitch and time manipulation
- Real-time sample scrubbing
- Per-voice grain and MIDI control
- Full MPE support
- Polyphonic 3D spatialization
- Binaural output using HRTF
- Grain animation with orbit, drift, or random motion
- Per-voice distortion and multi-effects
- AU, VST3, and standalone formats
- macOS, Windows, and Linux support
Two Ways to Work with Your Audio
- Single Mode: Evolving Pads, Textures, and Atmospheres
- Single Mode lets you turn any sound into evolving pads, textures, and atmospheres. Time and pitch are handled independently, with detailed control over grain behavior and real-time sample scrubbing. Slow the movement through a recording without lowering its pitch, or explore different pitches while controlling how the texture develops. Scrubbing lets you focus on a particular moment in the source, making it useful for finding a sustained layer within a short recording or developing an atmospheric bed for a cue.

- Multi Mode: Play Your Samples Across the Keyboard
- Multi Mode makes your samples playable across the keyboard. With polyphonic grain engines, velocity sensitivity, and full MIDI tracking, you can build new instruments from any audio source.
Use it when you want to perform a melody or chord progression with the character of your own recordings. Rather than working only with a continuous texture, you can shape the result through the notes you play and how you play them.

Immersive Spatial Audio
Stream Pro introduces a powerful 3D spatialization engine using Steam Audio’s HRTF technology. In Multi Mode, each note becomes its own spatial object. Place grains in stereo or surround fields, and animate them using orbit, drift, or randomized motion paths.
The interface includes an intuitive spatializer panel for fast, creative control over position and movement.
Per-Voice Effects and Distortion
Each grain or voice can be shaped with its own effects chain.
- Per-Voice Distortion gives each note a unique tonal character
- Grain-Level Processing applies distortion before grains are even mixed
- Choose from a curated selection of analog-style and digital distortion algorithms
- Combine distortion with spatial motion for highly detailed, immersive sound design
From cinematic soundscapes to playable granular instruments, Stream Pro is a self-contained granular ecosystem built for modern music production.
