Filters & Keytracking
Added 2024-06-05 14:29:40 +0000 UTCIn this video, I explain how I use filters and filter key tracking in Bitwig Studio. By using a subtractive synthesizer, I demonstrate the process of subtractive synthesis to manipulate harmonics, amplify specific frequencies, and achieve precise sound shaping without relying solely on EQ.
Key Points:
Starting Setup:
Use a single C3 note in a loop.
Adjust the synthesizer settings: saw waveform, remove default modulators, increase sustain, and use an EQ to visualize harmonics.
Subtractive Synthesis:
Use a low-pass filter to remove overtones, leaving the fundamental frequency.
Change filter steepness (e.g., LP2 vs. LP8) to affect the number of overtones removed.
Amplifying Harmonics:
Amplify the first harmonic for bass sounds to make them audible on weaker speakers.
Use resonance and filter frequency to target specific harmonics.
Key Tracking:
Use key tracking to maintain the relationship between the filter frequency and the note played.
Ensures the filter adjusts to different notes automatically.
Removing Harmonics:
Use a notch filter to remove specific harmonics.
Use calculations to target higher harmonics based on their frequencies.
Practical Use Cases:
Use filters to shape sounds precisely, making space for other instruments.
Apply key tracking and filter techniques in both monophonic and polyphonic contexts within Bitwig Studio.
This technique is powerful for sound design and can enhance your ability to create precise and impactful sounds in your music production.
Comments
Since you were wondering about the numbering of harmonics… “Well, actually…” The fundamental is the first harmonic. The second partial is the second harmonic and the first overtone. With inharmonic partials, things get a bit more complicated. https://en.wikipedia.org/wiki/Harmonic Otherwise, about doing those calculations… Was thinking about the little trick about typing in simple equations in the box for that value. Turns out, it doesn’t work with * for multiplication (maybe it uses something else?). It does, however, work with dividing by a decimal. So `262/0.25` gives you the value you calculated.
