DETACHING VS. UNLOADING
There are two ways to remove instruments from the MIDI mixer using the
MIDI Channel drop-down menus.
Detaching clears the Instrument from a MIDI mixer channel, but it remains
loaded in memory (RAM). Therefore, it can be recalled by a program
change either into the original channel to which it was assigned, or into an
alternate channel.
Unloading removes the Instrument from memory altogether. Use this if you
don’t expect to use the Instrument any more, thus freeing up RAM.
