Making stuff from scratch
Create a new set by clicking the Add New button to the right of the sets.
You'll see that by default you'll have a Drum Pads module for each of your hardware inputs. This is what a Snare Pads module will look like:
You can also delete these auto-generated controllers and start from a truly empty set, dragging in samples and modules from the Library panel on the left to build your own sonic layers:
The example above shows how you can quickly create two layers for two different drums: Snare 1 is controlling percussive sounds via the hit controller on layer 1 and a tom 1 is controlling the melodic sounds via the note controller on layer 2.
Add Your Own Sounds
You can add bookmarks to your own sample and set folders in the Library. Select the + button in the library under Folders. Now you can drag in samples (as well as sets and layers that you have previously stored in this folder) into your set.
"Generate From Selection"
You can right click on any module(s) and select "generate from selection..." and then choose the type of controller you want to generate. This will put whatever module(s) you have selected inside of the chosen controller. This is a really fast and unique way to work. You can, for example, drag a list of samples from the library and quickly put them all inside a Drum Pads (or any other controller) without opening up the Library panel!
