To edit a crosspoint, double left click on the crosspoint to bring up the Edit Crosspoint control. Once the edit
crosspoint control is opened, the crosspoint control always goes to its last position. After adjusting a
crosspoint, other crosspoints may be changed - without closing the edit crosspoint dialog - by left clicking
on the new crosspoint.
Multiple crosspoints can be adjusted simultaneously by pressing the control key at the same time the matrix
crosspoints are selected.
As shown in the previous figure, there may be different controls available on the edit crosspoint control
depending on the type of input virtual channel and output virtual channel. The following figure shows three
crosspoint controls - the first with a mono input to a mono output, the second with a mono input to a stereo
output, and the third with a stereo input to a stereo output.
