Consider a real drum kit. When you hit a single drum, sound is also reproduced in the nearby drums. You are going to learn how to make this effect from a sampled drum kit,  using a drum trigger and mixing in modified samples. To illustrate the effect listen to these two sound clips.

The original drum beat:

The drum beat enhanced with resonance:

In the example three drums are enhanced. Kick, snare and tomb.

That is done by creating their corresponding resonance samples composed of five low attack samples of the drum kit. Kick, snare, tomb, cymbal 1 and cymbal 2.

The waveforms displays the low volume of the samples. In a multisampled kit the low attack samples can be found being used at low velocities.

Creating the resonance samples
Put together the low attack samples and do leveling and panning. Also delay the samples individually. If you want to think in therms of a real drum kit, this would reflect the microphone placement. The further away from the mic, the more delayed.

- Kick

The kick resonance sample consists of low attack samples: snare, tomb, cymbal 1, cymbal 2. Mixdown as sample1.wav

- Snare

The snare resonance sample consists of low attack samples: kick, tomb, cymbal 1, cymbal 2. Mixdown as sample2.wav

- Tomb

The tomb resonance sample consists of low attack samples: kick, snare, cymbal 1, cymbal 2. Mixdown as sample3.wav

Trigger and mix with original samples
Now if you have a drum beat with at least kick, snare and tomb on separate tracks you can use the LADSPA Trigger to apply the resonance. But first you have to add the resonance samples to the trigger. Replace sample1.wav, sample2.wav, sample3.wav with the ones you’ve created. The path is: /usr/share/ladspa/samples/.

Insert the trigger to each track and step up the sample number to select the correct resonance sample. Then adjust the amount of saturation.

Contribute
If you make your own resonance samples it wold be nice if you share them with us. I see this as an effect, not just a way of making realistic drums. So go ahead and use your imagination.

This video shows how to create the effect somewhat similar to the one that can be heard in Telephone and Umbrella.

ShuttleEffect.ogg

Using the shuttle in Ardour you can control the playback speed. The positional sync source first has to be set to:

Then it’s possible to control the playback simply by dragging the shuttle. If you right-click you can set the max speed.

Play around with it!

To this date there’s no function to delete a plug-in effect preset in Ardour. A feature request has been filed and you can follow the status here. In this case we will delete an obsolete duplicate that has been saved under the same name.

Open the file:
~/.ladspa/rdf/ardour-presets.n3
On my system the .ladspa dir is located in the user home dir. If you’re using a file browser make sure you enable the “show hidden files” function. Before you edit the file remember to keep a back up.

In the image below the highlighted part represents the duplicate preset.

When the highlighted part is removed the preset is also removed. Open Ardour and have a look.

This works for every preset and to find the desired preset to be removed, start by searching for the name of the preset (line including #hasLabel). Then select everything from two lines down (line including #hasSetting)  up to the line below including next“#hasSetting” and delete selection.
