Elektron Musical Instruments

These is a feature that I'd like to see implemented in the next MD os 
update:

While working on new patterns, I often push some instruments to the max 
level, and can't go further.
Instead of having to lower all the other instruments one after the 
other, pressing FUNCTION while turning the level knob would change the 
level of all the instrument BUT NOT the current one.

Does someone else like the idea?
