Discussion about the Korg PolySix synthesizer

Correct -- even in Manual mode, it won't work.
The Polysix (& other "memory" synths) runs ALL of its control voltages thru 
the CPU -- any problem on the data or address lines will be reflected in 
the synth audio section.
I've never seen a battery-damaged P6 that didn't need at least SOME trace 
repair -- if you're fairly comfortable with reading schematics & tracing 
circuitry, this is do-able.  If you're not, you might want to call in some 
help.
