Bitwig Guides

The Mix modulator in Bitwig Studio allows you to crossfade between two values, A and B, which can be set to positive or negative amounts and used to modulate parameters like cutoff. You can also enable a per voice option to send different modulation values to each voice, making the modulation polyphonic and more dynamic. Additionally, combining it with other modulators like Random adds further versatility, allowing unique and expressive sound shaping for each note played.

The MIDI modulator in Bitwig Studio allows you to control parameters using different MIDI data like CC, pressure, and pitch bend, and you can easily map knobs from your MIDI keyboard using the learn function. You can filter incoming MIDI data by channel, making it flexible for setups with multiple controllers, and you must disable the PB Expressions option for standard pitch bend usage instead of MPE. Additionally, the per voice option in the inspector enables independent modulation for each note played, unlocking creative sound possibilities when used with advanced MIDI controllers.

The math modulator allows you to combine two modulation sources using various mathematical operations like multiply, add, subtract, minimum, maximum, and quantize, providing flexible ways to shape your modulation signals. You can control each input with knobs or modulate them further with sources like macros or LFOs, and the quantize option lets you set the resolution of your modulation in discrete steps. This tool is especially useful when you want to creatively process or combine modulation signals for unique sound design possibilities.

The Macro 4 interface modulator combines four regular macro knob modulators into one compact, space-saving unit on the modulator front end. It offers familiar options like switching between bipolar and unipolar modulation and supports per-voice modulation settings. Aside from these conveniences, it functions just like four individual macro modulators.

The Macro modulator allows you to assign a name, set a range from 0 to 100 percent, and morph between two different states of a synthesizer by modulating any parameter, even those nested within devices. You can switch between unipolar and bipolar modes and choose targets easily using the modulation handle, offering flexible sound shaping. This powerful modulator is especially useful for smoothly transitioning between presets or settings and includes per-voice modulation for added versatility.

The LFO in Bitwig Studio offers unique features, including audio-rate modulation and pitch-following based on MIDI input, making it versatile for both sound design and sequencing. It provides flexible synchronization options, customizable wave shapes, delay and fade-in functions, as well as polarity, phase, and polyphony controls for deep creative modulation. With these powerful tools, users can shape sounds, create evolving sequences, and even build entire synthesizers using the LFO module.

The Key-Track modulator adjusts modulation based on note input, allowing parameters like filter cutoff to follow keyboard note position, with C3 typically as the neutral center. By tweaking the center and spread, you can control how much and how quickly modulation changes as you play higher or lower notes, and the modulation works best on instrument tracks because they support note input. To apply Key-Tracking to audio tracks, a note receiver is needed to route notes from an instrument track, enabling features like key-tracked filters even on pure audio clips.

The HV/CV-In input modulator in Bitwig Studio allows you to use control voltages from hardware like Eurorack systems to modulate parameters within Bitwig, such as synth cutoff, using audio signals as control sources. You can adjust smoothing and gain to fine-tune the incoming signal and select between DC or AC coupling based on your audio interface, making it versatile for hardware integration. This tool is particularly useful for bringing the expressive control of Eurorack modular setups directly into your digital music production workflow.

The global modulator offers three handles, Fill, A/B, and Play, that let you modulate various device parameters based on different states, such as toggling fill, crossfading between A and B, or responding to the play button's state. These features allow for dynamic control, such as muting devices or adjusting filters, depending on whether you're in performance or mixing modes. Additionally, you can easily rename the modulator to keep your workflow organized.

The Expressions modulator in Bitwig Studio allows you to control multiple sound parameters individually for each note using keyboard velocity, MPE controllers, or by painting modulation curves directly in the note clip. This per-note expression makes your music more dynamic and organic, as every note can have unique modulation for factors like filter cutoff, timbre, or detuning. Features like smoothing and relative note start add further control, ensuring your performance or programming feels alive and responsive.

The Bitwig Studio Polysynth features two identical oscillators with flexible waveform shaping, unison, sync, blend operators, and the ability to blend with noise and modulate filter parameters. It offers robust filtering options, two envelope generators for amplitude and filter shaping, and extensive modulation and voice control for a highly customizable sound. Additional options and voice modes can be accessed through the inspector panel, providing versatile sound design capabilities.

The Button Modulator is a simple tool that lets you instantly apply a preset value to parameters like cutoff or enable switches in your device or preset. You can assign labels and stack multiple buttons for cumulative effects, and use the smoothing option to prevent abrupt changes or clicks by creating a gradual transition. This makes the Button Modulator particularly useful for toggling effects like reverb or quickly adjusting key sound parameters in your music setup.

The Beat-LFO syncs its speed to the project tempo, allowing you to blend smoothly between different beat divisions instead of making hard switches, keeping your modulation perfectly in time with your music. It offers flexible shaping options, bipolar mode, timing offsets, and even integrates with global shuffle settings for a groovy, dynamic feel. This makes it ideal for precise, tempo-locked modulation, and you can use other LFOs to modulate its speed without ever losing sync.

An Audio-Sidechain takes an audio signal, such as a kick drum, and transforms it into a modulation signal that can control various parameters on another track, like the volume or filter cutoff of a bass sound. This technique is commonly used to duck the bass when the kick hits, but it can also modulate many other aspects of a sound for creative effects. Using Audio-Sidechain modulation allows for dynamic and interesting sound design, making your music more lively and expressive.

The Envelope-Follower modulates parameters by tracking the volume shape of incoming audio, using settings like rise, fall, RMS, or peak to fine-tune its response. It only processes direct audio input, not audio from other tracks, unless you use additional tools like an audio receiver. For true sidechaining with external sources, it's best to use an audio sidechain modulator.

The new Channel-16 modulator in update 4.2 lets you assign different MIDI channels to various nodes, allowing for unique modulation of parameters like filter cutoff or waveform shape depending on the channel. This enables creative possibilities by making melodies more dynamic and expressive, as you can control both synth and effect parameters per channel. Additional features like global modulation amount and lag time help fine-tune transitions for smooth and versatile sound design.
