  Not a straightforward question to answer.  For modern synthesizers, the
most important chip is the digital signal processor.  For analog
polyphonics, the most important chip is still probably the microprocessor.
(Although I might argue the most important chip is the program ROM,
without which nothing runs. ;)

  For pure analog:

  First-place: the op-amp, starting with the 741.  Second-place,
the analog switch: CD4016/66, CD4051, DG308A, etc.
