There's plenty of sound generation hardware. DACs, PWM volume control, mixing voices together to form a stereo pair, pitch control registers, FM and AM modulation options -- this is all part of the sound generation hardware.

The only thing not in hardware is the waveform itself -- and that's a good thing!

A sample is a measurement of a signal. If the waveform comes from measuring a signal and storing samples into a memory then that's sample-based synthesis. If that waveform is derived analytically, then it isn't a sample. It's another form of synthesis -- wavetable synthesis.
