For a friend who has started exploring Plogue’s Bidule and asked me about how I set up the panning in some of my pieces. I use the mda “Round Pan” bidule, which can be used as either an Audio Unit or a VST (I use Audio Units first, then VSTs if the AU is not available).
So what follows is a series of screen shots and explantations, along with a brief, but extreme example of the results.
I started off with a simple Bidule, using a software MIDI keyboard called “MIDIKeys.” It’s a fast easy way to check how something sounds before hooking up a MIDI device to drive things. This drives two instances of Camel Audio’s Alchemy, one of them set to “Beth’s Violin” (on the left side) and the other set to “Tuareg Moon” (on the right side). I have inserted a MIDI Delay (“MIDI Delay_1″) on the right hand side, so that we hear “Tuareg Moon” come in 10 seconds AFTER “Beth’s Violin.” I hope this will demonstrate the panning a little bit more clearly.
1. In Figure 1 above, we have the basic layout of the Bidule. We also see the Mixer parameters, the MIDI Delay_1 parameters, and the Midi Keys parameters. Note that on the Mixer, Strip 1 and 2 are set at “Left” and “Center”, Strip 3 and 4 are set at “Center” and “Right” respectively.
2. In Figure 2 above, we click on the “Palette” button of Bidule, which then extends out the “drawer” displaying the “Available Bidules” … these are the various plug-ins and modules that are available for use. You can see that “AU Music Devices” is highlighted.
3. In Figure 3, we have drilled down to the “mda” section and selected the “Round Pan” bidule; specifically, the “02 ins 02 outs” (i.e., 2 inputs and 2 outputs).
4. To create the set up in Figure 4, we have double clicked to select the “2ins 2 outs” pan bidule and we now have two instances, here named “Round Pan_0″ and “Round Pan_1″ — these will be renamed so that #0 is “Round Pan_Left” and #1 is “Round Pan_Right” to keep track of what we’re doing …
5. Double clicking “Round Pan_Left” brings up the parameter screen where we will set its properties. Here you can see that the pan is 0° and 180° per second … we will change this. We attach the stereo outputs of the Pan bidules to the remaining four strips of the Mixer and leave them set to “Center.”
6. In Figure 6, we have entered values into the parameter boxes; in this case we have entered a +47° of pan and a rate of +5° per second (In the audio example, I have made the settings more extreme, using +178° of pan at a rate of +79° per second for the left side and -180° and a rate of -90° per second).
7. We will do the same thing for the “Round Pan_Right” but use different values for the amount of pan and the rate of panning. The reason for using different rates and amounts is to accentuate the differences … in this case, using negative values has the panning give an opposite apparent motion.
8. As seen in Figure 8 above, we enter a pan value of -45° and a rate value of -9° per second. And that’s basically how it’s done. Of course, one should experiment to see what works and sounds best for you!
Here’s a short audio file for an example, using the actual rather extreme parameters listed above to make things obvious:
… hope this helps!
