What is it?
GranuLab is a real-time granular synthesizer for Windows.

What: Granulation means chopping the sound into small overlapping segments and playing back just like the original, or twisted, or another time.
Howto: Open a soundfile and warp it -- time stretch, pitch shift, chorus or turn into static. Smooth transition to anything and back.
Control: Features: MIDI (mono synth style), MIDI (remote-control sliders), amplitude warp, random offset. More planned.

GranuLab 1.x is freeware.   Granny 8 is an extended version that you can buy -- it allows 8 soundfiles.

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.

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.
