PDO mk​.​2 + TBVCA - Demo 01 (Full Track)

from WMD PDO mk​.​2 + Triple Bipolar VCA by Matttech Modular Demos

about

This is the first of a suite of demos utilising the wonderful WMD Phase Discplacement Oscillator (PDO) mk.2 and Triple Bipolar VCA. I wanted to do demos that pretty much only comprised the various outputs of the PDO, showing what can be achieved with one instance of this module. I purposefully kept the riffs on these demos pretty simple, so that the sound manipulation becomes the primary focus. The only other synth part you will hear is a deep saw wave bass sound from Native Instruments Kore that was used to underpin the main riff at points (it enters at around 02.17). Everything else is a single recording of the PDO. It actually turned into something approaching a finished track, which was nice!

PATCH DETAILS:

1. The Moskwa sequencer is providing a sequence to the PDO via its 1v/oct input.
2. Outputs 1 and 2 of the PDO (both set to sines) are sent to mixer A, with outputs 3 and 4 (saws or similarly biting waves) being sent to a mixer B
3. Mixer A is recorded direct, and provides a nice rounded bass part - Channel 1 of the PDO is modulating Channel 2, via an envelope-controlled channel of the Triple Bipolar VCA. This has the effect of adding harmonics to the sound, taking it away from being simply a couple of sines. A nice rounded bass tone is produced, and the added harmonics make it easier to hear on smaller speakers - unlike pure sines, which can "disappear" somewhat. Phase Modulation (PM) is very similar to FM in a lot of ways, but without any pitch instabilities.
4. Mixer B - which contains the more "fizzy", trebly waves on channels 3 and 4 - is sent via the Pittsburgh Filter (In Highpass mode), and then on to the Modcan Dual Delay. This is so that the more "fizzy" sounds appear to be a second, distinct layer to the overall sound, due to their effects processing and delayed timing.
5. The Dual Delay's delay time and mix are both modulated by the vermona FOURmulator, which is producing slow sines wave LFOs.
6. As the recording develops the various controls on the TBVCA are manipulated, causing ever more interaction between the different channels of the PDO, eventually making the whole patch pretty gnarly.
