What's New in Bitwig Studio 4.0 [released 13 July 2021]

Audio Comping, Anywhere

Recording to the Arranger or Launcher

• To record on the Arranger timeline: new audio recordings are automatically added as comping take lanes when passing non-looping audio clips
  • For "cycle recording," just enable the Arranger loop
• To record into the Clip Launcher: from the Play menu, enable Record as Comping Takes, and set an appropriate Take Length
• Clips containing take lanes show the comping icon on their top right edge
• Since comping lives within the clip, comping clips can be freely dragged between the Launcher and Arranger
• Since comping lives within the clip, comping clips can be saved to your library, with take lanes intact and editable

Effortless Editing

• When a clip containing takes is selected, the Detail Editor Panel displays the Comping expression view for editing
• Each take lane is given its own color for visualizing the sources used, and each take can be renamed
• Take lanes can be reordered by dragging their headers
• Dragging over a portion of any take lane to create a comping region
• Clicking on any take lane uses that take for the nearest comping region and selects the region
  • Pressing [UP] or [DOWN] moves the comp region to the take above or below
  • Pressing [LEFT] or [RIGHT] selects the previous or next comp region
• Double-clicking a take lane selects it in its entirety as the current comp
• From the composite lane, dragging the top of any comping region up and down adjusts its gain
• From the composite lane, sliding the bottom of any comping region left and right adjusts its timing
• Sliding a boundary where two comping regions meet moves their fade point
  • Sliding a take boundary in the take lanes area also moves the transition point between comp regions
• Dragging near a boundary in the composite lane allows shortening a comp region to remove audio (including breaths, etc.)
  • Deleting a time selection within a comp similarly replaces the selection with silence
• [ALT]-dragging a take lane slides the time of that entire lane (and any comp regions pointing to it)
  • [SHIFT]-[ALT]-dragging a take lane slides the time of that all take lanes (and all comp regions referencing them)
• Comping expression editing keeps track of its own snapping setting, defaulting off
  • [SHIFT]-dragging temporarily inverts the snapping setting

Layered Comp Editing

• With multiple comping clips selected, layered editing mode of the Detail Editor Panel allows comp editing of multiple clips at once
• In the Comping expression view, the target layer shows all of its take lanes, and additional clips show only their composite lanes
• All comp editing gestures work as they do in regular (single) comp editing mode
• Using any of the comp editing gestures while holding [CTL] ([CMD] on Mac) applies that edit to only the single comp you are interacting with

Fold to Takes for Comping Any Source

• Wrap any audio clip into takes by right-clicking on it and choosing Fold to Takes
• Select either how many takes to create, or the length for each take
• Drag any audio file from the Browser Panel to the take lane area to add a new take lane
  • Right-click on any take lane header for Fold to Takes of that individual lane (in case a file is longer than the current comp, etc.)

Operators for any Note or Audio Event

Operators change when and how events are triggered. Devices have modulators; now notes and audio events have Operators. One or more modes can be used on each event.

Mode: Chance

• Sets the likelihood that any event will occur, adding probability to make any loop dynamic
• Is visualized on events like the face of dice
  • A higher die value represents a higher probability
• For notes, a Chance expression editor is available beside velocity

Mode: Repeats

• Causes retriggers within the original event, turning a single event into a ratchet, or polyrhythm, or…
• Repeat Value can be set two ways:
  • Values below 1 set the note rate for repeats (e.g., 1/2, 1/3, 1/12…)
  • Values above 1 set the number of slices the event is cut into
  • Right-clicking on this value provides a menu of common note rates
• Repeat Curve bends the repeats to either start closer together, or to speed up at the end
• For notes, Repeats End Velocity sets a relative target velocity for the end of the note repeat
  • This is also editable from the velocity expression lane
  • [ALT]-dragging on the end velocity point adjusts the velocity curve of the repeats
• Is visualized on events as slices where the repeats happen, just like the event restarts at each of those points
• Right-click on any event to Slice At Repeats, turning each repeat into an independent note or audio event

Mode: Occurrence

• Sets conditions for each event
• One Condition can be selected:
  • Always → Plays unconditionally
  • on First → Plays on first cycle
  • never First → Skips the first cycle
  • with Previous → Plays when last event did
  • without Previous → Plays when last event didn't
  • with Prev Key [note events only] → Plays when this key's last event did
  • without Prev Key [note events only] → Plays when this key's last event didn't
  • with Prev Chan. [note events only] - Plays when this channel's last note did
  • without Prev Chan. [note events only] - Plays when this channel's last note didn't
  • Fill on → Plays when Fill mode is on
  • Fill off → Plays when Fill mode is off
• The Fill button is a global performance control
  • It is available from the Play menu, and can be pinned beside the menus
  • It can be mapped to MIDI controller, or automated from the Master track under Transport > Fill
• Is visualized by displaying the condition icon on the event

Mode: Recurrence

• Gives each event its own looping timeline
• Recurrence Length sets the number of loops per cycle, from 2 to 8
• Toggles are then available for each loop
• So if the length is set to 4, four toggles are provided. And if only the first and last toggles are enabled, then this event will trigger on the first and fourth loops of this clip. (And then the fifth and eighth loops, etc. etc.)
• Is visualized on the event by a series of shaded (on) and empty (off) rectangles

General Workflow

• A new inspector section for Operators is available when note or audio events are selected
• All Operator settings are neutral by default, creating events that always sound
• When an Operator mode has active values, the mode is visualized on the note/audio event as described above
• Each mode icon represents a toggle that can be turned off and back on at any time

Take a chance on predictability with Expand

• Right-click on any Launcher clip and choose Expand to print any number of loops into a new clip
• Unlike Bounce options, Expand generates the type of clip you started with (so an audio clip will create audio clips, and a note clip will create note clips)
• Expand removes any Operator that can be calculated ahead of time (particularly good for "cycle-aware" options, like Recurrence, or the First conditions of Occurrence)
• Options are available to:
  • Preserve Chance values, instead of printing their result
  • Preserve expression Spread values, instead of printing their result
• This provides clips with predictable notes, and a visualization of how Operators are actually creating larger patterns within patterns
• When Chance settings are used, Expand a clip several times to glimpse into different possible timelines

---

Spread for any Expression Point

• Expression automation points each have a Spread value now, defining a range for the point that will be randomly selected each time the clip loops
• Notes have these per-note expressions that can use Spread:
  • Velocity (only defined at the beginning of each note)
  • Pitch
  • Timbre
  • Pressure
  • Gain
  • Pan
• Audio events have these expressions that can use Spread:
  • Gain
  • Pan
  • Pitch
  • Formant (used by some stretch modes)
• Random values will glide to and from their neighboring points, just as regular automation would
• [ALT]-drag on any expression point to define its Spread
  • When the clip is not playing, the Spread range will be visualized with a color gradient showing the bipolar range
  • When the clip is playing, the randomly selected values will be shown at the beginning of each loop cycle
• Spread values are also accessible in the Inspector by:
  • Selecting individual expression point(s), and using the Spread field in the automation Point section
  • Selecting a clip (or multiple note/audio events) and using the parameter's histogram, which now has a value for Spread of that parameter
• To grab a reproducible random sequence, each clip now has a Seed parameter
  • By default, the value is Random, producing different results each time the clip is triggered
  • By clicking this field, a particular Seed value is produced and saved (displayed as a shiny bit field)
  • To produce a new Seed value, just click the field again. Or click the die icon to return to total Random.
  • When recording a performance from the Clip Launcher to the Arranger, the Seed value used during recording will be preserved in the new Arranger clips, preserving the exact sequence playback as what you heard during performance.
  • This Seed functionality applies to all expression Spread values within a clip, as well as any Chance Operators used

---

New modulator: Globals (Interface)

• Provides modulator signals for three project-wide controls:
  • Fill - A modulator signal reflecting the current Fill mode state
  • A◆B - A bipolar modulator signal reflecting the current global crossfade value
  • Play - A modulator signal reflecting whether the transport is currently playing (1) or not (0)
• The Fill and A◆B sources can be used as global control sources, routing hardware controllers or automation (from Master > Transport) to any and all tracks
