● Since you use the Drum Map in Cubase VST to redirect certain note numbers 
(the ones that you play, the I-notes) to other note numbers (the ones that are 
sent back into your MIDI Instrument, the O-notes), this assumes that you use 
Cubase VST’s Thru-mode (and your instrument is in Local Off-mode). See the 
Getting Started book for details.
How Cubase VST looks at the Drum Map
“Inside” the program, the 64 Sounds each have a note number. This is neither the I-
note nor the O-note value, but simply a note number used to sort and keep track of 
the Sounds. This may seem superfluous knowledge for you, but it is actually only 
this “real” note number that is recorded, and as soon as you open a Drum Part in an-
other editor, the “real” note numbers will be revealed. The figure on the next page 
shows how the Drum Map system works when you record a Drum Part:
When you play a key on your 
keyboard controller, etc...
...the input is directed to the Sound 
with the corresponding I-Note. 
Internally, the “real” note number for 
the Sound (here: E0) is recorded.
Then, in order for you to hear anything, Cubase 
VST sends out the O-Note set for the Sound.
Finally, when you play back the recorded note, the program doesn’t care about the I-Note 
value, just looks at the recorded, “real” note number, and outputs the O-Note stored with 
that Drum Sound.
