Emu XL-7 & MP-7 User's Group

Hi
Recently purchased an mp7 and i'm lovin it. I have have a couple 
of questions though: Is there a way to set all notes on a track to 
the same velocity? I know you can scale but sometimes, on a 
bass for example, i just want all the notes being the same 
velocity after recording it live on the touch pads.
And erasing a track. Do i always have to select just the track i 
want to erase with the mute buttons and then try and remember 
which ones i had turned on after ive erased? cant u just erase 
the current track youre working on without erasing all the other 
tracks that arent muted? that would be so much easier.

One more comment, id love an undo button! If im recording a fast 
complicated rythm track in 2 or more runs im not gonna save in 
between each run. Undo to last time out of record mode.

Thanks
Great to see the emu people listening to this board
