Logic

HI , I met some problems when i'm using logic 8 in Piano Roll

1. If you have 5 notes in piano roll, and you select them all, and you open the note volecity hyperdraw which is down below, and you drag the velocity up , sometimes all the 5notes velocity will go up(increase), but sometimes 3 of the 5 notes will go up and the other 2 will go down,which means if you drag the velocity up(you move your mouse up while holding the left key) some of the notes velocity go up and the rest go down ... How can I move every notes' velocity up in this note velocity hyperdraw?
2. You first press command+C to copy, then you press command+v to paste,sometimes it pastes correctly, but sometimes, nothing is pasted and your view has been shifted(moved) to the end of the song,what's the problem?

英语不好,看不懂

虽然我看懂了英文，但我还没遇到这样的问题，力度嘛，我一般都是切换成力度光标后，单个或是选中某些来调整，可能是你的设置有问题吧~~~
复制粘贴之类的，我感觉是不是播放标尺位置错了或者是你点错了位置？

第二个我经常遇到,我也不明白,同问!~
