Designing Sound in SuperCollider/Cars

Fig 45.3: A "toy" engine
Instead of using a toggle object to simulate the break, the same functionality is implemented by moving the mouse cursor into the right or left half of the screen.

Fig 45.8: Advanced Engine
Advanced engine with multiple transmission paths and warping non-linear waveguide. Contains the subpatches from fig 45.5, 45.6 and 45.7. At the end there is also an example how to control some parameters via a MIDI controller.

For testing so many different parameters at once, a device with multiple controllers is your best friend.
