Sequential circuits samplers

<< Different keys for different sounds. Does not matter which key it is.I 
found 
if I keep taping a key untill I get the "white Noise", I keep that key 
depressed and it plays normally. So it has something to do with the voice 
allacation as you say. I can press the "stack-on-off" switch and this sort 
of masks it, but you can still hear it. Funny: the Internal sounds are 
unaffected, those work fine.So its not the chip ( Whew!)Must be a parameter 
setting.>>

don't panic yet. does it do this whatever disc you load? it could still be 
corrupted samples.... 
the internal waveforms are also in the sample memory, and I think they use it 
all, so it's probably not that. 

the internal sounds (all 16? if you leave "sound number" selected on the 
matrix, you'll see the numbers scrolling through as you play) sound ok 
wherever you play them, so the voice paths are ok..... (did you try them 8 
notes at once?) 

then it must be the disc, or possibly the drive or the driver circuit. the 
stack thing is a sort of variable unison; the number of voices each note 
takes up can be preset and over-ridden by a master setting, I recall. there's 
a lot of "execute" to switch things on and off aswell as the data entry 
buttons and knob; until you know this the machine appears impenetrable.

How so I turn the dynamic allocation off?? (untill I get the manual.) >>

there's an example. you select "dynamic allocation" on the matrix and it 
either says on or off, which you change with the inc/dec buttons. this'll do 
strange things if you have it plugged up in stereo and there's a sound loaded 
that uses samples in both halves; this is common on the "bigger" instruments 
on the factory discs I've got or seen, where they've designed it to work in 
machines with normal or expanded memories- the "normal" users lose a few 
notes at either end. but I digress.
to see if it's the sample as loaded that's the problem, select "sound number" 
on the matrix and press execute so the decimal point comes on. now the 
keyboard only plays that sound. you can check the whole lot this way, but 
it's also a useful trick to discover the useful (transposable) range of a 
sample. I think you have to press execute again before it lets you change the 
sound number.

this'll tell you if the discs you have were near a magnet or something. when 
you've seen the manual, you'll be able to load the sounds one at a time and 
maybe do some repairs. I got both of mine over ten years ago and the factory 
discs were often like that even then. if the machine checks out ok, you'll 
have a great time making your own anyway. what s/ware version is it? it'll be 
written on a prom inside somewhere near the middle, possibly obscured by the 
keyboard in the 2000. I can't remember. I'm reading the manual for the first 
time in maybe nine years and it's all coming back to me.....
