I would say an analog synthesizer is an analog computer. The input are for example voltages to simulate notes, and the computational output is a waveform. I prefer analog because digital synthesizer, at least for Subtractive synthesis, are only a simulation of the real instrument. The downsides are not unlike other analog computers, noise and dependence on temperature distort the output.
