Pseudo Granular Synthesis In Reason

Granular synthesis is a sound generation process that utilizes tiny bits of audio from another source, and plays them back at a rapid pace, in order to create sound.

If you want to check out some granular action in Ableton, here’s a short video we made for that too:

Using Reason, you can chop up samples into pieces without leaving the program. First, you need to create a Redrum drum computer. 

Next, you’ll want to notice that depending on your channel number, the bottom left knob on the Redrum will function differently.

You have three, four, and five channels where the function is “START”. 

In other words, if you load the sound file of your choice into channels 3, 4, or 5, you can change the sound file’s beginning point by using this function. 

You can load any sound file that you like (vocal sounds are good) into channel 3, and then turn the length knob for channel 3 to the left. 

This way you can get a short burst of sound.

As a next step, while holding Shift, click on an empty space in the rack with a right click (or command-click for Mac users) and select “Matrix Pattern Sequencer”. 

Now, you will need to flip the rack around with the Tab key, and then drag a cable from the Matrix to the Redrum, using the “Gate CV” on the Matrix to the “Gate In” on the Redrum. 

After you have flipped the rack around again, press the Run button on the Matrix. Now, you should hear a stuttering sound.

You will hear the effect that we were looking for when you turn the Start knob. 

Using the Start knob automation button on the sequencer (make sure the red Record button next to “Redrum 1′′ lights up red when you press record, and then press play), you can automate the start knob. 

You should be able to get some cool sounds by adjusting the pitch and start time.

There is also an even cooler feature: you can adjust the speed of gate triggering in the matrix by adjusting the Resolution knob…
