Maestro was a synth made in USSR that was designed by Vladimir Kuzmin of Polivoks fame. Maestro takes after Polivoks but adds digitally controlled oscillators and 4-voice polyphony. I learned a few things from studying its circuits.

Some counters, a DAC, a bunch of cd4052-like analog muxes and switches, opamps and even a 555. They use DIN symbols. Unless you want to replicate it exactly, most things can be guessed.
There’s also a BBD chip for chorus.
