Colorfield Mix Stage

Quick start

1. Name your tracks with clear words (Lead Vocal, Kick, 808, Bass, Gtr, Keys, Pad). Colorfield reads the names to guess each track's role, and plots place tracks by role (see Roles).
2. Insert Colorfield on every track you want in the mix, as an insert effect on mono or stereo audio tracks. It is not an instrument and takes no MIDI. Its output is always stereo: on a mono track in Logic Pro, choose the Mono → Stereo version. Keep every Colorfield in your DAW's main plugin process, not bridged or sandboxed, or the stage shows only some tracks (see Hosts and limits).
3. Open any Colorfield window. Every track with Colorfield on it stands on the stage. A Colorfield you just inserted places itself after a moment, at the spot for its role or at the nearest clear spot. If the license window at the top right reads LOCKED, Colorfield stays silent until you activate it or start a trial (see Installation and activation).
4. Choose a room in the header.
5. Play the song, then choose a plot under PLOTS to place every track by its role in one step.
6. Drag tracks where you want them: left and right for the stereo place, forward and back for distance. A track moved back gets quieter, up to 10 LU. To keep its level, start dragging, then hold Shift.
7. Click the COLLISIONS chip at the lower left to see which tracks mask each other, and click APPLY to make a suggested move.

How the stage works

• One stage: every Colorfield in your session joins one stage. Any Colorfield window shows all of them and edits all of them.
• Every edit belongs to its track: an edit always lands on the Colorfield that owns the track, as that track's own setting. It is saved with that track and your DAW can automate it (all but the array), even when you make it from another track's window. SOLO and ROOM ONLY are listening aids and are not saved.
• One room: the room settings (Room, Room Size, Brightness, Room Amount, Listener Seat and Listener Array) are copied into every Colorfield on the stage, so each one holds its own copy.
• No delay: the direct sound is never delayed. Moving a track changes its level, tone, stereo place and room, never its timing. Colorfield reports 0 samples of latency to your DAW.

The window

The header runs across the top. The stage fills the window below it, with the selected track's deck floating at the right and the COLLISIONS chip at the lower left. Each window opens at 1440 x 900 with its own track selected and the deck open. Drag the lower right corner to resize it from 1152 x 720 to 2560 x 1600; it keeps its 16:10 shape.

The header

123456789

1. Room. The room every track shares.
2. SEAT. Where the mix is heard from.
3. Array. The stereo pair that hears the room.
4. Scenes A to D. Four stored stages.
5. PLOTS. Place every track by its role.
6. Undo and redo. Step through your changes.
7. STAGE and PLAN. The two views.
8. MORE (···). Reflections for every track.
9. License window. LICENSED, TRIAL or LOCKED.

Each marker sits just left of its control.

The stage

12345

1. The selected track. Lit in its color.
2. Its label. Name, distance and DRR.
3. Ring and pool. The light on the floor.
4. Every other track. Lit by its own level.
5. The listener. The array at the seat.

Each track stands in the room as a glass shard, lit by its live level. It takes its host track color when the host sends one with a clear hue, or else its role's color (a track with no recognized role gets a color of its own). Its pool of light on the floor widens with WIDTH.

The selected track carries a ring around its pool and a label with its name, its distance and its DRR (direct-to-room ratio, in dB: higher means drier and closer), the same value as DIRECT / ROOM in the deck. The selected track, or the one under the pointer, shows its reflection paths: lines from the track to the points where its sound strikes a wall, and on to the listener. Choose MORE > Show every track's reflections to draw them for every track.

The listener is the array you chose in the header, standing at the SEAT position.

STAGE and PLAN

12

1. The selected track. Its ring, from above.
2. The listener. Where the reflection paths meet.

STAGE shows the room in three-quarter view. PLAN shows it from above, for exact placement. Everything works the same in both. Press P to switch.

The deck

1234567

1. Name window. The track's name and role.
2. CLOSE. Hides the deck.
3. Readouts. Where the track stands.
4. PLACEMENT. WIDTH, AIM and AIR.
5. Value windows. Click one to type.
6. ROOM. REFLECTIONS, ROOM SEND, OUTPUT.
7. LISTEN. LEVEL LOCK, SOLO, ROOM ONLY.

The markers sit at the deck's left edge; CLOSE's sits at its right.

The deck belongs to the selected track. Its name window shows the track name (Track, when the host sends none) and its role, beside a lamp lit in the track's color. CLOSE hides the deck. To open it again, click another track or press Tab; clicking the track that is already selected does not reopen it.

The readouts show what Colorfield made of the track's place: DISTANCE (meters), ANGLE (degrees; 0 is straight ahead, negative is to the left), DIRECT / ROOM (dB) and FIRST REFLECTION (ms).

PLACEMENT

ROOM

LISTEN

SOLO and ROOM ONLY are listening aids. They are not saved with your session and undo leaves them alone.

Working the knobs: drag to adjust, hold Shift for fine control, and use the mouse wheel to step (Shift for fine steps). Double-click a knob, or Cmd-click (Ctrl-click on Windows), to reset it, and click a value window to type a value. Each knob turn, wheel burst, reset, typed value or LEVEL LOCK press is one undo step.

Placing tracks

Moving tracks

• Click a track to select it and open its deck.
• Shift-click adds a track to the selection, or takes a selected one out.
• Drag to move the selection. Left and right set its place in the stereo picture; forward and back set its distance. A selection moves together, stops at the edge of the stage and keeps its shape.
• Cmd-drag (Ctrl-drag on Windows) moves at a quarter of the speed, for fine placement.
• The arrow keys move the selection 10 cm; with Shift, 1 cm; with Cmd (Ctrl on Windows), 50 cm. Up moves it away from you.
• Tab and Shift-Tab select the next and the previous track.

Depth is distance

Depth is spaced so that equal moves back sound like equal steps further away from the front row. As a track moves back, its direct sound gets quieter, the room around it grows, the air softens its highs, and its close-mic warmth fades. Without LEVEL LOCK, a track at the back of the stage can be up to 10 LU quieter than at the front.

Move without changing the level

Start dragging, then hold Shift to keep the track's loudness from that moment: Colorfield adjusts its OUTPUT as it moves, so only the space around it changes. The whole drag is still one undo step. (Shift as you click adds a track to the selection or takes it out.) To hold the level on every move, turn on LEVEL LOCK in the deck.

Movement and your DAW

A move writes the track's own Position X and Depth parameters. Colorfield sends drags and scene glides to your DAW as automation gestures, so you can record them with your DAW's automation. Automating a room setting on one track moves the whole stage; see One room.

Rooms and the listener

The rooms

Choose a room with the arrows either side of the room window, or click the window for the list. Sizes are at Room Size 100 %.

Three room settings have no control in the window. Reach them through automation or your DAW's parameter view:

• Room Size, 70 to 140 % (default 100 %): scales the room.
• Brightness, -100 to +100 % (default 0 %): tilts the room's surfaces brighter or darker.
• Room Amount, 0 to 100 % (default 20 %): from a dry studio to a live room. At 0 % the reflections and the tail are off. It is set relative to each room, so the same amount gives the same wetness at the front of the stage in any room.

To change one, set it on any one Colorfield, then click SETTINGS DIFFER · SYNC in any window to copy it to every track. The Stage app has no parameter view, so there these three settings stay at their defaults.

One room

The tail is identical in every Colorfield only while they share the same Room, Room Size and Brightness, and the stage keeps them matched. If the tracks disagree on any of the six room settings (Room, Room Size, Brightness, Room Amount, Listener Seat or Listener Array), the room window reads SETTINGS DIFFER · SYNC. Click it to give every track the settings that were changed most recently. It is one undo step.

A Colorfield you add to a stage takes the stage's room settings by itself, about a second after it opens: the most recently changed ones, as SYNC would. This works in every DAW, Pro Tools included. One loaded from a preset, a track template, a paste or a saved session keeps the settings it was saved with, so a session reopens exactly as you left it, and it joins the stage it's opened on. If its settings differ from the stage's, the room window reads SETTINGS DIFFER · SYNC, and SYNC gives every track the most recently changed settings.

Automate a room setting on one track, or change it in your DAW's own view of the plugin, and the whole stage follows once the change holds for a moment (about a quarter of a second). If two tracks automate the same setting differently, nothing follows: each track keeps its own automation, and the room window reads SETTINGS DIFFER · SYNC, so the room never jumps back and forth between them.

SEAT and the array

SEAT sets where the mix is heard from, from the front row (0 %) to the back of the room (100 %). The seat moves for every track at once.

The array (the window that reads ORTF, SPACED or XY) sets the stereo pair that hears the room:

• ORTF (default): two cardioids 17 cm apart at 110 degrees. Natural width with time and level cues.
• Spaced pair: two omnis 60 cm apart. The widest, most spacious picture.
• XY: two coincident cardioids at 90 degrees. Level cues only, the most solid in mono.

The array changes how the reflections and the tail are picked up. The direct sound is panned the same way with every array, so it stays mono-safe.

Plots and roles

Plots

PLOTS places every track by its role in one step. There are eight factory plots:

• What a plot sets: each track's position, depth and width. In every plot, the vocal's spot also sets its REFLECTIONS to -6 dB and its ROOM SEND to +4 dB: up front, with its tail in the room.
• What it leaves: the room, the seat and the array.
• Who goes where: within a role, the loudest track takes the most important spot, so play the song before you choose a plot. A track with no recognized role takes the plot's spare places.
• A plot is one undo step.

Roles

Colorfield guesses each track's role from whole words in its track name (in the Stage app, the file name). For example, "Vox" or "Lead Vocal" is a vocal, "808" is an 808, "Kick" or "BD" is a kick, "Gtr" is a guitar and "Pad" is a pad. A track with no recognized word is Other.

When several words match, the longest one wins, so "Lead Vox" is a vocal and "Bass Drum" is a kick. Upper or lower case does not matter.

Track names come from hosts that pass them to plugins. Many VST3 hosts send the track name and color. AU hosts can send only the name. A track with no name is Other. There is no control to set a role by hand: rename the track in your DAW to change its guess.

Scenes and undo

Scenes A to D

• Store: Shift-click a scene key. Storing replaces what the key held, and undo cannot bring it back.
• Recall: click it. Every track glides to its stored place over 1 second.
• What a scene holds: each track's position, depth, width, aim and LEVEL LOCK. The room, the seat, the array, AIR, REFLECTIONS, ROOM SEND and OUTPUT are not part of a scene.
• Each Colorfield keeps its own scenes, saved with your session. A track you add after storing a scene stays where it is when you recall it.
• A recall is one undo step. Undo puts back each track's position, depth, width and aim, but not LEVEL LOCK.

Undo and redo

Use the UNDO and REDO keys in the header, or Cmd + Z to undo and Cmd + Shift + Z or Cmd + Y to redo (Ctrl on Windows). Hold the pointer over UNDO to see what it will undo.

• One step each: a drag or an arrow-key move, a knob turn, a typed value, a LEVEL LOCK press, a plot, a scene recall, a room, seat or array change, a suggested move and a SYNC.
• Not on the list: storing a scene, and SOLO and ROOM ONLY, which are listening aids.
• Per window: each open Colorfield window keeps its own undo history, up to 100 steps. Closing the window clears it.

Collisions

123456

1. The pair. Each lamp in its track's color.
2. Where. The frequency they mask most.
3. How much. The longer the lit run, the more.
4. The suggestion. A move that clears it.
5. APPLY. Makes the move.
6. CLOSE. Folds the list back.

Each marker sits above its item; APPLY's and CLOSE's sit at their left.

The COLLISIONS chip at the lower left counts the pairs of tracks that mask each other where they stand. Click it to open the list; CLOSE folds it back to the chip.

• What it measures: how much two tracks fill the same frequencies at similar levels (40 bands from 50 Hz to 12 kHz, read from each track's own input), times how close they stand. A step in depth separates two tracks more than the same step across.
• The list: up to four pairs, worst first. While it is open, the stage draws a thread between each pair.
• The suggestion: a move for the less important track of the pair, in meters, for example "Move Hats 0.69 m back: 47 % less masking." A move under 0.1 m reads "a step".
• Which track moves: the less important one, in this order, most important first: Vocal, Lead, Bass, 808, Kick, Snare, Keys, Guitar, BGV, Strings, Brass, Hats, Toms, Overheads / Room, Perc, Pad, FX, Other. Between two tracks of the same role, the quieter one moves.
• Where it goes: the nearest spot, within a short distance, that cuts the pair's masking by at least 40 % while adding little or no masking with the other tracks.
• APPLY: makes the move. It is one undo step, named "Suggested move".
• "No nearby place clears it.": no spot close by helps. Move one of the tracks yourself, or change its sound.
• Play the song: the list reads the live audio. Tracks that are bypassed, muted by a solo, set to ROOM ONLY or quieter than -70 dB are left out. "Nothing on this stage masks anything else where it stands." means no pair masks enough to list.

The Stage app

12

1. The message. Drop a folder anywhere on the window.
2. OPEN. Choose a folder of stems.

Each marker sits just left of its item.

The Stage app mixes a folder of stems on the same stage, with no DAW. In Applications (the Start menu on Windows) it is called Colorfield Mix Stage.

• Open stems: click OPEN or press Cmd + O (Ctrl + O on Windows) and choose a folder, or drop a folder or audio files on the window.
• What it reads: WAV, AIFF and FLAC files at the top level of the folder (not subfolders), mono or stereo. A file with more channels uses its first two. Each stem can be up to 12 minutes long; a longer file is cut at 12 minutes. Stems at another sample rate are converted to your audio device's rate, and shorter stems are padded so every loop lines up.
• The session: each stem becomes its own Colorfield on one stage. File names become track names and role guesses, and the session starts placed by the "Pop: vocal forward" plot. Everything in the window works as in the plugin: rooms, the listener, the deck, plots, scenes, collisions and undo. With no parameter view, Room Size, Brightness, Room Amount and Tail Mode stay at their defaults.
• Sessions are not saved: export before you quit. Opening another folder replaces the stage without asking.
• Audio output: the app plays through your computer's default audio output.
• License: the Stage app uses the same Colorfield license or trial as the plugin. Without one it plays silence, and EXPORT MIX opens the license card.
• Its own stage: the Stage app's stage does not show the tracks of a DAW session that is open at the same time.

The transport

1234567

1. OPEN. A folder of stems.
2. Session. Its name and stem count.
3. BACK, PLAY and LOOP. The transport keys.
4. Playhead. Where you are.
5. Timeline. Click or drag to move.
6. Length. The song's length.
7. EXPORT MIX. Renders the mix.

Each marker sits just left of its control; the timeline's sits above it.

Keyboard and mouse

Keys work when the Colorfield window has keyboard focus: click the stage once. Some DAWs keep certain keys for themselves.

With VoiceOver, each track on the stage reads its name, distance and angle. Press it to select it, then move it with the arrow keys.

Parameters

Every parameter your DAW sees. "(room)" marks the six room settings, which are copied to every Colorfield on the stage.

• Monitor is a listening aid and is not saved: every Colorfield opens in Normal. Mono and Direct Only are reached only through this parameter.
• Bypass is the same switch as your DAW's bypass. Bypassed, Colorfield crossfades to your dry track over about 21 ms (at 48 kHz) while its room keeps running underneath, so turning bypass off never restarts the room.
• Extra steps. Some DAWs list more steps than these for Room, Listener Array, Tail Mode and Monitor. Use only the named steps. An extra Room step plays the Tracking Room while the window shows the Concert Hall; an extra Listener Array step plays ORTF, an extra Tail Mode step plays Full and an extra Monitor step plays Normal.

Tail Mode: Full and Eco

Each track has a Tail Mode.

• Full (default): the track sounds in the room completely, with its direct sound, its early reflections and its share of the room's tail.
• Eco: the direct sound and the early reflections only. The track still stands in the room and reflects off its walls, and its reflections play a little louder so it keeps the same amount of room, but it adds nothing to the room's tail, and the tail's processing does not run for it.

Use Eco on tracks that need little room, or when your computer runs short. Keep Full on the tracks that carry the room. Tail Mode has no control in the window: set it per track in your DAW's generic parameter view for the plugin, where your DAW offers one. It cannot be automated.

Hosts and limits

• Each Colorfield always renders its own track correctly. Its sound depends only on its own track and its own settings. Nothing from another Colorfield reaches its audio.
• The shared stage is certain only with every Colorfield in one host process. Some DAWs can run plugins in separate processes: a plugin run bridged, or each plugin in its own sandbox. A Colorfield in another process may not appear on this stage, so the stage is only partial. Its sound is unaffected, but edits you make on the stage (room, seat, plots, scenes) do not reach it. Host every Colorfield in the same process, then reload the session.
• Inputs and outputs. One input, mono or stereo; stereo output. No sidechain and no MIDI. On a mono track in Logic Pro, choose the Mono → Stereo version; in a DAW whose mono tracks stay mono, put mono sources on stereo tracks.
• Latency. 0 samples, reported to your DAW. The direct sound is never delayed; the room's reflections arrive after it, as in a real room.

A Colorfield that finds itself alone

If a Colorfield was saved on a stage with other tracks and opens with none of them in sight, its window shows a short note at the upper left of the stage. The note says how many tracks it was with, names the fix for your DAW and says that its sound is unaffected. It goes away as soon as the Colorfield finds the others. A Colorfield left alone because you deleted the other tracks shows no note.

A Colorfield loaded from a preset, a track template or a paste can carry the stage of the project it was saved in. A few seconds after it opens alone, it joins the stage it's opened on, with its own settings unchanged. If your DAW has two projects open in one process, each with its own stage, it can't tell which one is its own, so it stays where it is and shows the note.

Specifications

• Inputs: mono or stereo. Output: stereo.
• Latency: 0 samples.
• Tail: the longest tail any room can ring, reported to your DAW.
• Rooms: six, installed once for every format and the Stage app (47 MB of room pictures). The sound of every room is built into the plugin.
• Sample rates: 44.1 to 192 kHz.
• Buffer size: does not change the sound.
• Memory: about 1 MB per Colorfield at 48 kHz.
• Processing: Eco skips the room tail's processing for its track. A Colorfield also rests once its input is silent and its room has died away for a quarter second, and wakes on the next sound, so a stopped song costs little.
• Window: 1152 x 720 to 2560 x 1600, 16:10; 1440 x 900 when it opens.
• Formats: AU, VST3 and AAX on macOS, VST3 and AAX on Windows, and the Stage app on both.
• Systems: macOS 10.15 or later on Intel, macOS 11 or later on Apple Silicon; Windows 10 or later, 64-bit.

Not included

• There is no control to set a track's role, name or color by hand; they come from your DAW.
• The Stage app does not save sessions and has no parameter view, so Room Size, Brightness, Room Amount and Tail Mode stay at their defaults there.
• Colorfield works on mono and stereo tracks. It does not support surround or Atmos formats.

Installation and activation

Install

1. Download the installer from vitricaudio.com/downloads or your account at vitricaudio.com/account.
2. Save your work and quit your DAW.
3. Run the .pkg (Mac) or .exe (Windows).
4. Open your DAW. If Colorfield is not listed, rescan plugins.

Use AU in Logic Pro, AAX in Pro Tools and VST3 in other DAWs. The installer also puts in the Stage app and the six rooms. On macOS:

• AU: /Library/Audio/Plug-Ins/Components
• VST3: /Library/Audio/Plug-Ins/VST3
• AAX: /Library/Application Support/Avid/Audio/Plug-Ins
• Stage app: /Applications, as Colorfield Mix Stage
• Rooms: /Library/Application Support/Vitric Audio/Colorfield/Stage

On Windows:

• VST3: C:\Program Files\Common Files\VST3
• AAX: C:\Program Files\Common Files\Avid\Audio\Plug-Ins
• Stage app: C:\Program Files\Vitric Audio\Colorfield Mix Stage, with a Start menu entry under Vitric Audio. A custom install can leave it out.
• Rooms: C:\ProgramData\Vitric Audio\Colorfield\Stage

The installed rooms are the pictures of the stage. If they are missing, the stage says "The rooms are not installed." Your tracks still sound right, because the sound of every room is built into the plugin, but the stage can't be used until you run the Colorfield installer again.

Activate your license

Until you activate a license or start a trial, Colorfield passes no sound, the license window reads LOCKED, and a large LOCKED mark with "UNLOCK AT VITRICAUDIO.COM" sits over the stage. The license card opens by itself once each time you open the window. Open it any time by clicking the license window in the header.

1. Open the license card.
2. Paste the VT-... key from your purchase email or account page. Lost it? vitricaudio.com/license can resend your keys.
3. Click Apply license.

A full license works offline after activation and runs on up to three computers at a time. The Stage app uses the same license. Sessions always reopen with their settings, whatever the license state.

Activate a computer that is offline

1. On the offline computer, open the license card and click Copy code to copy its machine code (it starts with VTM1-).
2. On any computer that is online, open vitricaudio.com/license, enter your key and the machine code, and download the license file.
3. Copy the file to the offline computer, open the license card and click Load file.

Try it free for 72 hours

1. Open the license card and click Start free trial. The trial page opens with the product and machine code filled in.
2. Sign in with the emailed link and click Start my 72-hour trial.
3. Click Copy trial key, paste it into the license card and click Apply license. Or click Download license file and use Load file. A backup copy is emailed to you.

The trial has every feature, runs 72 hours from issue and needs an internet connection while you use it. There is one trial per product, person and computer, and no payment details are needed. During the trial the license window reads TRIAL and the days left. When it ends, Colorfield goes silent but keeps every setting in your projects.

If the license window reads LOCKED during a trial, the card says "Trial verification required": connect to the internet and click Retry trial.

Updates

Colorfield asks vitricaudio.com once a day, while its window is open, whether a newer version exists, and sends only the product, your version and your platform.

1. Click the license window in the header to open the license card. When a new version is out, it shows UPDATE AVAILABLE with the new version and yours.
2. Click Download (the button shows the new version number) to open the product page and get the installer. The notice stays on the card until you install the new version; Later does not hide it.
3. Quit your DAW and run the new installer over the old one. Your sessions reopen as saved.

Colorfield has no switch of its own for the checks: it follows Check for updates in the Options menu of your other Vitric plugins. With no other Vitric plugin on this computer, the checks stay on.

Troubleshooting

Colorfield does not appear in my DAW

Rescan plugins and restart the DAW. In Logic Pro, use Logic Pro > Settings > Plug-in Manager and Reset & Rescan Selection. On Windows, make sure your DAW scans C:\Program Files\Common Files\VST3. In Pro Tools, quit and reopen Pro Tools so it scans the AAX folder. Colorfield 1.0.0 has no AAX version, so Pro Tools needs 1.0.3 or later.

The stage says "The rooms are not installed."

Run the Colorfield installer again. Your tracks still sound right; only the pictures of the rooms are missing.

A track is silent

• The license window reads LOCKED: Colorfield has not been activated, the trial ended, or the trial needs to check in. Open the license card from the license window.
• A solo or ROOM ONLY is still on: they stay in effect when you select another track, and their keys go dark. Click SOLO on and off on any track: every track plays normally again, ROOM ONLY included. Reopening the session does the same.

Some tracks are missing from the stage

Your DAW is probably running them in another process (bridged or sandboxed); see A Colorfield that finds itself alone. Host every Colorfield in the same process and reload the session. Their sound is unaffected meanwhile. A track that is disabled or offline in your DAW has no running Colorfield, so it is missing from the stage too.

The room window reads SETTINGS DIFFER · SYNC

The tracks disagree on a room setting, usually because a Colorfield was loaded from a preset or a saved track with other room settings, or two tracks automate a room setting differently. Automation on one track alone moves the whole stage. Click it to give every track the most recent settings. It is one undo step.

The collisions list stays empty

Play the song: the list reads live audio. Tracks that are bypassed, muted by a solo, set to ROOM ONLY or very quiet are left out. "Nothing on this stage masks anything else where it stands." means no pair masks enough to list.

The mix got quieter after a plot or a move

Tracks further back are quieter, as in a real room: up to 10 LU at the back of the stage. Raise OUTPUT on the tracks you want louder, or bring them forward. To move a track without changing its level, turn on LEVEL LOCK, or start dragging and then hold Shift.

A plot puts tracks in odd places

Plots place tracks by role, and roles come from track or file names. Name tracks with clear words (Vocal, Kick, 808, Bass, Gtr, Keys, Pad), then choose the plot again. Undo takes back a plot in one step.

The exported mix cuts off the room's ring-out

EXPORT MIX ends where the longest stem ends. Add silence to the end of one stem to keep the tail.

My computer runs short

Set Tail Mode to Eco on tracks that need little room, and close Colorfield windows you are not using.

Shortcuts do nothing

Click the stage once so the Colorfield window has keyboard focus. Some DAWs keep certain keys for themselves; use the mouse for those.
