Due to the fact that so many manufacturers use Control Change #91 and #93 in the same way, they should be renamed according to their common usage.

Details: Sets Control Function names as follows:

CC# (hex) [Old Name] [New Name]
===================================
91 (5BH) [Effect 1 Depth] Reverb Send Level
93 (5DH) [Effect 3 Depth] Chorus Send Level

The actual response is dependent on a formal R/P such as General MIDI Level 2 Recommended Practice.
