I think the primary design philosophy behind the GX1 was that, while 
comprised of voltage-controlled voice cards, it was an Electone; that is, 
it was designed by the Yamaha Electone organ divison and as such, it was a 
stage organ first and a synthesizer second.  The voice signal path,

  was meant to make it possible (I think) to create flutes, diapasons, 
reed and brass in a manner at least familiar to organists.  Gary 
Leuenberger once told me that at the US introduction of the GX1 in San 
Francisco in 1974, the concert crowd was rather neatly divided into those 
who were 'offended' at the un-organlike nature of the machine, while the 
other half were awed.

  In keeping with the user-configurable harmonic structure for organs, 
the GX1 has overtone triangle-wave doublers and filter-based harmonic 
selectors, things that did not, for example, migrate to the CS-80:
