Blocks can be created by dragging & dropping from the top menu, and come in four categories: Source, Effects, Power & Interaction.
They will connect with other suitable blocks automatically when in close proximity, which is indicated with connection lines drawn between the blocks.
Source blocks create a source of sound, ( a sample, an oscillator, or a microphone input etc) and can have effect blocks connected to them which will in some way alter that sound.
To start creating sound, a Source block must either be powered with a connected Power block, or controlled with a connected Interaction block.
Each block has it’s own settings. Single-clicking on a block will open it’s options panel where various effect parameters can be changed or played.
