The general patch always shows four input- as well as four output ports per
engine. Because two engines are provided, the total of shown patch points is
always eight input- and eight output ports.
Patch connections now can be made as with other sources and targets. Once
connections are made, they will also be indicated in the FX Engine Setup
window :
As a shortcut for 'patching to effect targets' and 'from effect sources', it
is also possible to doubleclick into one of the eight label areas in the setup
window. This then navigates directly to the general patch, to the desired target
or source.
