Pins and cables

Pins are a module's inputs and outputs; a cable joins one to another. Cables are typed and will not connect across kinds.

Kind	What it carries
Stream	A value every sample: audio, or anything at audio rate.
Event	A discrete occurrence: a note, a trigger, a MIDI message.
Value	A control position that holds until it changes, like a knob.

Each kind draws in its own colour, so you can see what is moving through a patch before you read a single label. A pin only accepts a cable of a kind it understands, which turns a whole class of patching mistake into something you cannot express.

Seeing the signal

Cables show what is running through them. A patch that makes no sound tells you where it stopped: the last cable carrying anything is the last thing that worked.
