(may 2010): Support 24/32-bit files. Fixed clicks starting/stopping. (version "T10" and free 1.2)

(march 2008): Interpolation choices for much cleaner sound. Faster engine. (version "T8" and free 1.1)
(may 2003): Granny 8: MIDI update. Each stream has its own MIDI channel. Better crude/fine control for sliders ("waggle" mode - see help file)

What is it?
GranuLab is a real-time granular synthesizer.
Originally (1998-2018) for Windows, now as VST 2 plugin for MacOS and Windows.

What: Granulation means chopping the sound into small overlapping segments and playing back just like the original, or twisted, or another time.
Howto: Load a soundfile and warp it -- time stretch, pitch shift, chorus or turn into static. Smooth transition to anything and back.
Control: Random, LFO, Soundfile amp/noisiness, from MIDI input, or by internal params.
Effects: Fold, overdrive, bitcrush (smoothed), dual filters (SVF), delay.

If you like GranuLab (and you're on Windows) you might want to try Coagula. (on MacOS MetaSynth is the original, and much more advanced)



VST 2 version

GranuLab.VST Windows (2018-12-16)
GranuLab.VST MacOS (2018-12-16) (64-bit only, OSX 10.9 or later)

GranuLab 8-stream
Use 8 grain streams simultaneously.
The streams are independent -- like using 8 Granny 1's at the same time. Streams can be muted and soloed.
Each stream can be controlled by MIDI notes and sliders to its own channel (channels 1-8).

As of Sept 1, 2012, GranuLab 8 is the basic freeware version.

NOTE: These plans are from about 2002. And look what happened only 16 years later!

GranuLab^2 plans.
Preliminary and subject to changes. No time schedule.

• New interface - rotation knob sliders and pretty picture of soundfile.
• Live input - Capture phrases and/or use a buffer of N last seconds of input sound.
• More control options - LFO's, automation, connect sliders across streams, support BMP units etc.
• Support OSC.
• N-band filter on input sound, each outputs a grain stream. Another sound can control N-band filter; this allows granular vocoder effects.
