i think you're right about the hardware dependency.  in the FAQ (or maybe 
was the digest) someone mentions this problem as happening "occasionally".
but with my unit it happens every time.  i use a lot of textural loops, so
the clicks really stand out.  i'm glad to hear it's fixed in the upgrade,

i played with my plex some more and i think you're right about the signal
levels.  the problem is i like to make loops with widely varying dynamic
ranges.  but when i keep the signal at the point where the orange light is
usually on (tricky to do without clipping), it sounds much better.
furthermore, the noise i was talking about is kind of a buzzy digital
overtone that occurs on an input signal is present, probably due to the
inherent dynamic range of digital audio.

from the URL i mentioned (www.thechipmerchant.com) i ordered four of the
60ns 4MB SIMMS for 29 bucks each.  the price was actually the same for the
70ns.  also, thanks for the input on "low-noise" simms - i think with my
fairly complex signal path, which produces a certain amount of its own
noise, any benefits from fancy-schmancy simms would not be noticeable.

one more newbie question:  will the legendary "upgrade" be just a rom chip
that can be bought at a store and user-installed?  or is there some kind of
magical ceremony that must be performed by a qualified tech/priest?

thanks for the help, kim!
