CC11 is the MIDI Expression control.

Think of it like the Expression Pedal on an organ.

It controls Volume, but in a slightly different place than the CC7 Volume command does.

The CC11 corresponds to the individual volume faders on a mixer.

CC7, on the other hand, corresponds to the Master Volume Fader over at the end of a mixer.

So, if you have a MIDI file that contains both CC7 and CC11 events, any CC11 commands will control the volume of whatever MIDI channel it is assigned to, whether one or more, usually only one at a time, BUT -- its overall volume can't go higher than the CC7 setting.

In other words, if CC7 were set to 90, you could turn a track's CC11 up to 127 alright, but it could not exceed that CC7 setting of 90.

This is more powerful than it first appears, as it really can make a huge difference in the mix of a MIDI sequence.

If you strip out ALL of the CC11's in the file or on a track, then it is likely that the sequencer will default to a CC11 setting of ZERO or no volume at all.

I can't imagine a good reason to strip out CC11 commands, typically they were put there by the MIDIOT who wrote the file for good reason. But with all the free downloadble MIDI files about, there easily could be some that aren't up to snuff for a variety of reasons. In that case, it may be far better -- and far easier -- to go out websearching for another MIDI file of the same song, which may just beat trying to put a saddle on a dying horse in the first place.
