Drum Replacement

It’s happened to us all: that take that you spent hours on in the studio the night before actually sounds terrible the next day. Maybe your ears played a trick on you, and you didn’t pick up on mistakes when you were recording due to fatigue. But before you spend time on a brand new recording, try rescuing your take by using drum replacement. To prepare for this kind of situation, today we’ll concentrate on replacing and fattening up the drums after recording.

Listen to the following drum recording:

In this workshop, we want to modify the sound of the snare in the recording.

Step 1: Set the snare track to “solo” and notice the crosstalk components.


First, we want to remove as much crosstalk as possible so the MIDI trigger track doesn’t pick up any false snare hits.

Step 2: To remove the crosstalk, we’re going to insert the eFX_Gate plug-in, select the “Snare Cleanup” preset and the appropriate threshold to the effect that all snare hits can still be heard while the crosstalk signal components are suppressed by the gate.

Step 3: Now we want to create a MIDI trigger track for the new snare sound. To do this, we’re going to activate the snare audio object and open the audio quantization wizard by going to “Object” > “Quantize” > “Audio Quantization Wizard” in the menu.

Step 4: Transients display abrupt acoustic inputs in the signal. Under “Detect Transients”, set the sensitivity so that each snare hit is represented by a beat marker (AQ) by dragging the “sensitivity” slider to the right until

an “AQ” with a red border appears in front of all transients.

Step 5: Now we want to transfer the beat markers (AQ) to a new track to be used as MIDI triggers for our drum replacement. To do this, go to “Object” > “Quantize” > “Extended audio quantize” > “Generate MIDI Trigger from Transients”.

As you can see, a new MIDI track (“Trig Snare”) with the detected transients displayed as MIDI events

Step 6: In the track editor, go to “MIDI” > “Out” and select the Vita Solo Instrument “Rock Drums” > “Rock Drums Stadium” to be used as a sound generator for our MIDI trigger track.

Step 7: Double click the MIDI object to open the MIDI Editor and switch to Drum Editor by clicking the corresponding button.

Listen to the triggered notes. If the generated trigger events don’t sound like a snare, select them all (Ctrl + A) and move them to the trigger sound you want with the up or down arrow.

Step 8: Monitor the timing of the original track and trigger track and move the trigger track object forwards or backwards until the original track and trigger track optimally complement each other.

In our example, we are placing the trigger events slightly ahead of the audio track hits because we want the trigger signal to stand out. We also don’t want any flam effect, which would result from placing the quieter signal before the louder one.

Step 9: Now mix the two snare sounds together. In order to give the trigger track volume fader control of the audio signal, right click the fader in the track header and select “controls Audio Volume and MIDI Velocity”.

Step 10: Finally, adjust both snare sounds using the EQ. We recommend thinning out the original signal somewhat in the fundamental range at 150 Hz to prevent the two snare sounds from getting in each other’s way in the bottom end.

From this point on you can feel free to fine-tune the snare signals according to the rules of mixing.
