Side Chain in Bidule
Tutorial - Using MIDI Connectivity in a Modular Host (Plogue Bidule)

Tutorial Description

This tutorial shows you how to use the MIDI connectivity of our plugins in a modular host such as Plogue Bidule. We are using the Mac version of Bidule in this tutorial.

The scenario here is very simple: we will be using a first audio source (Audio Source 1) to modulate the volume of another one (Audio Source 2). It can typically be used for side chain compression, ducking, automatic voice over etc. We will be using the Peak Meter Pro plugin, but the tutorial is applicable to any of our plugins with MIDI output.

Step By Step

01 - Start with two audio sources and the main mixer:
Step 01 - Start with two audio sources and the main mixer
02 - Drag and drop the Blue Cat's Digital Peak Meter Pro plugin (VST or AU):
Step 02 - Drag and drop the Blue Cat's Digital Peak Meter Pro plugin (VST or AU)
03 - Connect the Blue Cat's Digital Peak Meter Pro (aka DPMP) audio input and output:
Step 03 - Connect the Blue Cat's Digital Peak Meter Pro (aka DPMP) audio input and output
04 - Drag and drop the Blue Cat's Gain plugin:
Step 04 - Drag and drop the Blue Cat's Gain plugin
05 - Connect the gain plugin audio inputs and outputs:
Step 05 - Connect the gain plugin audio inputs and outputs
06 - Connect the MIDI output of the DPMP to the MIDI input of the gain plugin:
Step 06 - Connect the MIDI output of the DPMP to the MIDI input of the gain plugin
07 - In the DPMP, enable the transformed envelope MIDI output and setup the MIDI CC channel and number:
Step 07 - In the DPMP, enable the transformed envelope MIDI output and setup the MIDI CC channel and number
08 - Open the preset settings for the gain plugin:
Step 08 - Open the preset settings for the gain plugin
09 - Enable MIDI for the gain parameter and set the MIDI CC channel and number to the same values as the DPMP output:
Step 09 - Enable MIDI for the gain parameter and set the MIDI CC channel and number to the same values as the DPMP output
10 - The gain for the second audio source is now controlled by the transformed envelope of the first audio source:
Step 10 - The gain for the second audio source is now controlled by the transformed envelope of the first audio source
11 - You can now tweak the parameters to control the side chain:

You can change the parameters of the envelope in the Digital Peak Meter Pro as well as adjust the MIDI response curves and value ranges in both plugins to adjust the response of the side chain.

Conclusion

You are now able to use the MIDI capabilities of our plug-ins in a modular host such as Plogue Bidule. It is possible to create many audio-controlled effects thanks to this technique, using any of our audio plugins as a destination for the MIDI messages sent by one of our plugins with MIDI output.
