Using Plugins & Adding Real-Time DSP FX
Dec. 17, 2002 --Arranged by Ryan Beisner.
Thanks to Dan Harper for pointing out the details and to every participant
of the Ardour project.

This section assumes you already have the following: a session with at least one track and region set up to play; JACK is running and Ardour is connected to it; LADSPA plugins are installed. If you're this far, you probably have all of this by now. After all, you compiled Ardour without errors, right?

Now's the time to load your existing session, or build a new one (not covered
here). Here, we use an existing session ("Drop In A Bucket" by BEINWE)
with 6 tracks and several regions.

Adding the Effects
We're going to add a few effects to the vocal track (VOX1).
- Go to Ardour's Editor window.
- Click on the "redirects" button in the track control area of the desired
track.

- Click the "Edit" button in the DSP chain window.
Fig. Add-DSP 1-6 Adding plugins.
- Select a plugin from the list and click the "Add" button.
Notice we added a couple more effects. You can too. It will take
some playing around to find the effects you like. Delay is a pretty
common and simple plugin, so we'll start there. It's a sound idea to
add only one effect at a time and see what it really does.

- Hilight the "Simple Delay Line" DSP chain and click on the "Edit" button.

- Adjust the attributes as shown or however you like.
- If you want to save these settings for later use, click the "Save"
button and give it a name.
- Go to Ardour's Mixer window and look at the panel for the track to
which we added the DSP plugin.

- Clicking on an effect in the list will toggle it on/off. Yellow
= OFF Blue = ON
- Just in case the colors change with future development and/or configuration
changes, those listed within parentheses are OFF.
- Enable the desired effects...

- Return to the Editor window and PRESS PLAY!
- You can now make adjustments to the DSP plugin's attributes to tweak
it to your taste.
