Hello,
   I think it would be useful to be able to filter the event list contents by arbitrary parameters. When working with synths and sample libraries, it's sometimes easiest to enter keyswitches or CC's for volumes using the event list. This is especially true when trying to make changes to many tracks at once. But because viewing either notes or CC's is an all-or-nothing proposition, it's harder than it could be to see what's up.
 
If I could filter to show only notes below C1 (where most of my keyswitches live), I'd be able to see easily which keyswitch was most recently used to know if it's correct. It would also make it easier to enter new ones, as right now my new entry can sometimes get lost in the sea of existing events. For CC's, I'd know if my volume/expression controllers were correct if I could filter to only those events.
 
Thanks for considering,
Mike
