Ok, so quick rundown for you: put GranularSpectrogram4channels.sc in the Extensions folder, recompile the class library, boot the server and run GranularSynth.scd. You should run this on on 3.8.0 or greater otherwise you are gonna have problems with the GUI. Use MONO samples only!! Go at the bottom of this page if you need some.

So, first of all download supercollider from here. If you already have supercollider installed on your machine, make sure you are on 3.8.0 or greater otherwise you are gonna have problems with the GUI.

You'll notice you have 2 files in this repo:

• GranularSynth.scd
• GranularSpectrogram4channels.sc

The .scd file is the one you are going to run in the SC enviroment, while the .sc one is a new class for our language, so we must add it to the class library of supercollider.

How so? Open up supercollider, and type

Platform.userExtensionDir

Now, evaluate: put your cursor on the line of code and press Cmd+Enter (macOS) or Ctrl+Enter (win).

You will get in the post window a Path to the Extensions folder of supercollider. Try to reach that path. This can be difficult since some folders might be hidden, so the best thing is to copy the path in the file explorer. Moreover, the folder might not exist, so you may need to create it yourself. You can do this in your operating system's file explorer or from within supercollider by evaluating:

File.mkdir(Platform.userExtensionDir)

Quick stupid tip: if you want to manually create it and you can't reach the parent folder, just delete \Extensions from the path and go there from the file explorer.

Just be sure that the folder is named Extensions, that the folder is in the right parent folder as suggested from the path supercollider provides you, and paste right there GranularSpectrogram4channels.sc. Nothing too difficult.

Okay now, go into the supercollider enviroment, and go for Language > Recompile Class Library. Now we have our custom class! Next thing we need is to boot the supercollider server. Press Server > Boot Server, and when the numbers in % at the bottom right go green, we are ready to go. Open the GranularSynth.scd file, press Cmd+A (macOS) or Ctrl+A (win), then press Cmd+Enter (macOS) or Ctrl+Enter (win). This shall start everything and you should be able to load samples, play them and have fun with everything in the pack. If you want more info on the synth, check the .pdf. Oh, and be sure to use MONO samples! What, you do not have any? Grab some here, they are free and you can even donate them something!
