Creating a sequencer-based drone with BazilleCM

-

1

Let’s start things off by initialisi­ng a patch on BazilleCM. Open up your DAW and load up the plugin. Once the plugin window is open, move to the central display at the top of the window, click to reveal the drop-down menu, and select ‘init’ from the bottom. This will initialise the patch. 2

As part of the initialisa­tion, you’ll also hear the FX Delay active in the signal. To make our adjustment­s clearer at this stage, go to the Delay section (bottom-right) and move the switch to the ‘off’ position. You can always switch it on again later, if so desired. 3

Move to the OSC1 section and adjust the Tune pot to a value of 12. Remember that every time you make a pot adjustment, the value will be displayed in the upper-display. Locate the PD pot, which is located halfway down the OSC1 strip, and set this to a value of 36.50. 4

Next, patch OSC1 to the filter section. Disconnect the existing patch cable from OUT1, and reconnect it to the input of the Filter section. You should be able to do this by clicking and holding on the end of the cable. Once connected, create a second patch cable from the filter output LP6, to the input of OUT1. 5

Now that the filter section is connected, we can adjust the associated tone elements. Begin with the Cutoff pot, which we need to set to a value of 58, and then adjust the Resonance pot, to a value of 41. The sound we hear now will be quite dull and intense, but this will change very shortly! 6

It’s time to patch in the first section of the sequencer. Using the sequencer’s output point which is located on the left, patch a cable to the PD modulation pot, within the OSC1 section. Then set this pot to a value of 70. Adjust the first four sequencer faders to values of 0, 20, 32 and 24.

Locate the second sequencer output point. You will see a number associated with this point, which relates to the note value being played by this section of the sequencer. Change this value, from the drop-down menu, to a value of 4. Then patch a cable from this location, to the first filter modulation pot, within the filter section. Once connected, set this pot to a value of -40. 8

Much like step 6, we need to assign the next batch of four sequencer faders, to the values 0, 40, 22 and 52. When you play a note, you will see that the sequencer starts to play, but you should also note that this section of the sequencer is running four times slower than the first section. 9

Locate the final patch output point, within the sequencer section, and create a patch cable from this location to the input of the upper Lag Generator. Then patch an output from the Lag Generator to the second filter modulation pot. Moving back to the Lag Generator, set the Attack pot to a value of 2.3, and the Release pot to a value of 1.6. 10

In order to hear this element of the patch, we will need to do two things; firstly, adjust and experiment with the remaining eight faders on the sequencer, which will in turn have an effect on the filter cutoff control. By adjusting the Filter Modulation pot, we can increase or decrease the effect applied by the sequencer. Try setting this pot to a value of 66 as a starting point.

Moving to the OSC2 section, set the PD pot to a value of 50. Then create a patch cable from the output of Envelope 2, to the PD modulation pot. Set this pot to a value of 38. We also need to connect the output of OSC2 to the OUT1 section, and reduce the OSC2 volume pot to 30. 12

Finally, we need to adjust both of our Envelopes. Set the Envelope 1 faders to Attack 12, Decay 50, Sustain 100 and Release 14. Envelope 2 will modulate the Phase Distortion of OSC2, so adjust these faders to Attack 50, Decay 60, Sustain 22 and Release 20.
