Granular Synthesis and Timestretching

Create a Grain Sampler by Phi Sequence
If you’ve ever used the Malstrom in your projects, you’ll undoubtedly see the benefit of grain synthesis. It’s like sound design under a microscope, as you can take a very short piece of sound and chop it up into little bits and start/stop the playback where you like. The fact that you can’t add your own grains into the Malstrom is somewhat disconcerting, but there’s a simple way you can create your own grain sampler, where you can add any sound and use that sound as a grain. This can be very effective in adding some new creative spark to your musical projects. And it opens you up to adding any sound you like and deconstructing it as you see fit. So let’s see how we can do this.
Patches and ReFills
Grain Sampler by Teknolab
Grain Sampler requires Teknolab Grains. Grain Sampler enables you to change pitch without changing the speed, or changing the speed without changing the pitch. It uses a NN-XT Sampler with 127 samples. Each has it’s own gate value assigned. A combination of 3 Malström cv outputs and a matrix cv-signal produces a complicated cv-signal that is used as the gate in of the sampler. The signal will trigger the sampler very frequently while the gate value rises more slowly, effectively triggering the samples one by one in the right order.
Granular Key Sampler by Dioxide
A granular sample Combi that is synced to Note on so it can be used as an instrument. Uses an arpeggiator to trigger the sampler on Note on.
G-Drum Granular Drum Machine by Dioxide
The G-Drum is a granular sample drum machine for Reason. This version contains four drums with adjustable pitch and grain size triggered by a Redrum drum machine.
Granular Tutorial ReFill by Resonant Filter
The Malstrom synthesizer in Reason uses graintable synthesis. And while I love it, the one thing I think it’s really lacking is the ability to load your own waveforms. Here’s a little trick on how to use a NN19 sampler in a combinator as a Granulizing device. I’ve made the combinator template available for download, but I think it would be best if I explained it a bit.
Granular Synthesis & Time Stretching by Document02
The idea behind this synth is to loop-read a very small bit of a sample through an NN19, and advance through the sample to fake some time stretching. If you don’t advance, you have a granular synth. A compressor has been integrated in the unit for the simple reason that playing with the knobs real time can produce some peaks, this allows for more time to think for the musician.
Granular Snare Hit by Peff
You might have seen the YouTube Video, or read the article I wrote for the Computer Music Reason 4.0 special, or seen a few of the examples I put in Thor Step Sequencer Refill. Here’s a personal variation of the granular sampler. This is a one shot mode created specifically for drum hits.

Reason 4 Grain Shifter Effect Part 1 by NedRush
this one is quite complicated but works great. trying to emulate the buffer overide plugin in reason 4. delays loop tiny fragments of incoming audio to create grainy effects. delay time can be modulated to create grain shifting. this is in now way granular re-synthesis, just a delay effect which sounds almost similar. will try and upload asap.
