congratulations with the pss-390
i read back from my old post, that i found only 3 chips interesting ;
.
the 25 pins i soldered to the YM7129 , LC3564PL and the XG314BO.
i wanted to finish it quick, so i didn't invest the other ic's somuch as they didn't seem interesting
my other investments i don't remember, but certainly you would find more if you take time.
but on these 3 ic's you will be save i guess. mine always recovered from a crash after powering up again.
i did it patchbay style, with an external box. i found most bents pretty stable, in the sense that you always get the same madness in a certain patch. on the other hand it could be totally unpredictable. in some patches it sounds totally strange, but the sliders still function as usual, in other patches they trigger glitches.
on some of the patchpoints i used to connect an antennae, so it could interfear with digital streams in the area,
like cellphones, bluetooth etc, wich seem to modulate the fm carriers (or something
)
very nice. also the display acts realy superb, almost scary sometimes
the sound of this keyboard is also very nice. the stereo can be very wide.
in general i see this board bended as an intergalactic broadcast receiver, at least that's how it sounds
580 i don't know. just be carefull around the DC inlet area . try to search for datasheets on ic numbers.
if it has the same ic's as the 390, your a lucky basterd
with midi !
and dont forget to interconnect them ! and let us hear some mp3..
good luck !
