Comment: Presets versus Snapshots
Since the last software upgrade 3.3 we encountered some misunderstandings regarding the
protected patch points, snapshot filtering and the meaning of presets. We would therefore like to
add some comments on this topic: It is important to know that the difference between snapshots
and presets has grown against previous software versions. Previously a preset was the same as a
snapshot with the difference that it existed only once per session configuration (rather than per
title) and it could only be altered by the system administrator. Now we regard the preset also as
more powerful than a snapshot, ignoring all filters and protections which may be active. The reason
is that since the introduction of sophisticated snapshot filtering and partial snapshots, it is not 100%
sure anymore that recalling a snapshot is putting the whole console into a defined audio state. But
being able to do so is necessary. This is the difference to Presets. When recalling presets, the whole
console is put into a 100% defined state of audio, as it was when the preset was created. This
happens regardless of protected patch points or filtered parameters. However, the fact that some
parameters may be filtered or protected against changes by snapshot recalls stays active. As soon as
any snapshot is recalled, the rules of filters and protections are valid as before.
