3 In the Drum Replacement/Doubling dialog, set the following parameters:
•
Instrument pop-up menu: Choose the drum sound you want to replace or double (Kick, Snare,
Tom, or other).
•
Mode buttons: Choose one of the following modes:
•
Replacement: The new sound replaces the original, and all regions on the original track
are muted.
•
Doubling: The new sound is added to the original (the original sound is not muted).
•
Relative Threshold slider: Set the threshold value for transients, above which trigger notes
are generated.
•
Prelisten button: Click to start playback of both the original (audio) and replacement (software
instrument) track from the current playhead position. The two tracks are soloed, so all other
tracks in the project are silent.
You may want to set the playhead or activate the cycle area to prelisten to a part of the
project requiring special attention for drum replacement. Click Prelisten again to stop
playback, return the playhead to the previous play position, and unsolo the two tracks.
•
Trigger Note pop-up menu: Set the pitch of the trigger notes created on the software
instrument track. Choosing AUTO (the default setting) sets the trigger note as follows:
•
Kick = C1 (36)
•
Snare = D1 (38)
•
Tom = A1 (45)
•
other = C3 (60) and AUTO menu not available, as there is no automatic choice for
this setting.
Note: Any changes to the trigger note do not change the instrument setting. However, any
changes to the instrument setting change the trigger note, either to Auto or C3 (60).
•
Timing Offset slider: Shift the position of trigger notes earlier (negative values) or later (positive
values). The offset should normally be set to 0.0 ms (which places the MIDI trigger notes
exactly at transient timing positions), but may need to be adjusted when using your own, or
third-party, instruments.
•
“Set average attack time” button: Set the average offset of all regions on the source audio track.
4 Click OK to confirm the action.
Clicking OK resets the vertical zoom of the original audio track, mutes its regions if you selected
the Replacement option, and deselects the track. MIDI trigger notes for the EXS24 are created on
the software instrument track, and the track is selected.
