Syntorchestra-4_Service.pdfThe Farfisa Syntorchestra 4 is a very similar synth to the Farfisa Soundmaker, with a few missing features and a slightly less rich string sound.
The Synthorchestra 4 is essentially a cost/complexity reduced Soundmaker, the many individual gate cards for the poly voices of the soundmaker are now integrated into a single pcb. there are less controls for the mono section, and even the service manual lacks the fantastic theory of operation section.
it still sounds great, but lacks a bit of the flexibility of the soundmaker.
but it does weigh a little bit less.
