Hi,
I now have my SX-210 and it's in a bit of a bad
way.
When turned on for the first time all the lights
where on and nothing appeared on the display. It also made no sound apart from a
faint high pitched static noise.
I started to explore the settings and found every
one to be on 99. So i reduced things like noise, hpf, res, vca/vcf attack times
and it made a nice full sound.
I began to suspect that it hadnt been switched on
in a while and the battery was dead. Poly8 mode barely works. Only occasional
notes play. Poly4 is better and it seems pretty much okay in mono mode. Some
keys dont sound at all while others play notes without regard to envelope
settings.
So i opened it up and found a nice orange crystal
growth around the battery and some corrosion of IC legs in the general area. The
wires that link the trwo main boards looked sound enough but had a touch of
corrosion at their joints. It looked surprisingly neat and tidy in there, not at
all like the innards of my Jen SX1000.
I intend to take the two boards to work with me
tomorrow (fortunately im an electronic technician so i have the tools!!) and
give them a proper going over as well as getting a replacement
battery.
The longer ive had it on, ive seen subtle
improvements in its behaviour. For ecample, i can now store patches and recall
them.
I hope i can get this thing to work because i had
it making a sound not too far away from a CS80. Oh and i like the "LFO START"
button. I think it should really be called the "Complete Madness" button
instead!
