Pitch tracking is a common synthesizer feature that doesn't get talked about much. It can be ultra important when filtering bass line sounds that travel a few octaves as when you are using a low-pass filter on the oscillator and you travel to a note above the frequency cutoff, the sound gets much quieter and might be non-existent. Key tracking follows the 1V/Octave signal that is controlling the oscillator, opening the filter more when the pitch travels higher.
In this video, we go how to set up a pitch trackin patch with the WMD C4RBN filter. We discuss attenuating the pitch signal and mimicking features found on classic subractive synths. We also go into using the self oscillation feature of C4RBN to create a nice sine-wave oscillator and how to turn that into a banging 808 like bass line machine.
**Be sure to listen to the Self Oscillation demo on headphones or studio monitors as the sine wave is tuned too low for laptop speakers**
