Typically on every major write you lose a few cells, and there are usually quite
a few alternates for every location.  Over all it will take quite a while for
your machine to fail on something like this, but all nonvolatile flash style ram
suffers from this, and I'm sure there will be a radio shack replacement part for
$1 by the time it fails.  Alesis QS series have this problem in aces, since you
have to reburn the entire card every time.

Subject: [xl7] Flash RAM life expectancy?


From the OS 2 manual addendum:
"Because Flash RAM has a finite number of write operations before
it goes bad, the Command Station will not allow you to manually compact
when there is more than 100K bytes of compacted memory remaining."

This got me *really* worried.

How many read/write cycles will the Flash RAM endure before it fails
and make a Command Station unusable? Will a XX-7 be still usable 10
years from now without having to seek for replacement parts, or is it
just a disposable synth? Floppies were cool after all...

And still no function to SWAP tracks inside a pattern in OS 2.0 for,
say, timing priority purpose?

Oh well... Thanks anyway. :)

Easy enough to bounce it to a new track, and do the swap that way.  And 
the Apply Clipboard features means all your other settting can come along 
too now.  So yeah, no dedicated Swap feature, but easy enough to do still.

Don't worry, I believe it's around 100,000 write cycles.  That
translates to about 50,000 compactions (each compaction is one write,
the other one is the sum of all the parameter writes to cause it to
need compaction).

Try using X-Mix.  You can select the current pattern by selecting a
different pattern, then reselecting the current one.  Note that you
won't be swapping tracks, but it should be pretty quick if you have a
spare track.

Thanks for clearing that out Aaron (and for OS2.0 BTW!).
Even if FlashRAM life expectancy decreases each time a pattern is 
saved (if I understand correctly), 100,000 cycles look quite a lot
anyway. :)

Implenting a SWAP TRACK function in OS2.1 would be cool. 
If any. :)

Not that I complain, of course.
