Hi,
1) The environnement:
Windows seven 64 Pro SP1 (offical) / 8g RAM / Intel core i7 3770k
Cubase 8 Pro (offical)
2) The issue:
0: Prerequisite: Have an audio track
1: Edit the audio track by double cliking on
2: select a reasonable small area and press “control+c” to copy it in the clipboard
3: select on another place a target area LONGER than the copied one
3: open “Merge clipboard”
4: apply it => The merged is done as expected
5: Undo it:
Result => The original audio is not restored/is truncated, and the audio is corrupted/lost
5 bis: To see the bug multiple times, just redo/undo multiple times (Control+Z then Control+shift+Z)
Note: This NOT occurs if selected target area is smaller than the one to be merged
