A bit complex so I may have easily made a mistake.
Cue 1 and cue list two where recorded with both dimmer and scenic element channels.
Then two partitions were created ( 1,2) 1: with dimmers 2: with scenic elements
Partition 1 add to Cue list 1 and partition 2 add to cue list 2
then in blind with cue list 2 you can type
1 Thru 99 delete cue 1 thru 99 <enter>
Does delete all the the dimmer channels created
Now when on cue list 1 to delete the scenic elements that were accidently recorded before partitions created
100 Thru 199 delete cue 1 thru 99 <enter>
Says channel list empty
but you cant do
100 delete cue1
So it looks like you can't delete ranges of scenic elements when partitions are enabled.
