Circuit Overview:
     A combo of the 'mono' and a Orchestra basically. The Sequential Circuits 'Fugue' is the same machine with different silk screen, as with the Orchestra 2/Prelude which they also bought from Siel to diversify their product line.

Service Tips:
      Never worked on one but see mono and Orchestra notes.

I have several scraps from Siel units and lots of the discrete parts.
