Was not Multi-sampling already a feature of Silverfast AI a while ago? Can Multi-sampling and ME be used together?

Multi-Sampling eliminates image noise reliably
In response to many customers' requests LaserSoft Imaging has decided to provide every SilverFast SE Plus and SilverFast Ai version with the Multi-Sampling feature from today.

Image noise does occur quite often during the scanning process, especially in the darker areas of images. The CCD sensors are taking a very small amount of light here. Therefore the difference between the signal and influences such as dark current, production inaccuracies and noise of the output amplifier is very small. This leads to "strayed pixels", which are denoted as image noise.

SilverFast Multi-Sampling is able to eliminate this image noise by taking advantage of the strayed pixels' random occurance. Thus, they are never at the exact same spot, when scanning the same original several, subsequential times. Multi-Sampling takes up to 16 single scans of an original and therefrom calculates a final result, which is devoid of noise, but unaltered else. SilverFast Multi-Sampling does work even with those scanners, for which their manufacturers haven't intended such a feature in the hardware at all.

Dear hassiman,
the key word here is "every".
This means that beforehand some Ai versions came with Software Multisampling enabled without an extra fee and some came without this feature as standard. ( due to historical reasons and talks with the manufacturers ).
Now every Ai and every SE+ has this feature enabled for the standard price.

Thats just it :-)
