Synths and keyboards: protect keys, joysticks and protruding controls

On synths and keyboards, identify keys, pitch/mod wheels, joysticks, sliders, encoders and knobs that could receive pressure.

Avoid hard material bearing directly on the keys. The package should support the instrument through the chassis and stronger areas while keeping the control surface clear.

For long instruments, consider flexing as well: a box that bends in the middle can transfer load to the keyboard even when the corners appear protected.
