Blazar Core

Less time in menus. More time for music.

Blazar Core keeps the technical side of writing out of your way. Your Kontakt libraries sit one drag from the arrangement. The edit menu opens right at the pointer. Four effects blend with one move. And the busywork can go to Claude Code or Codex while you keep writing.

  • Drag Kontakt programs from the browser straight into the arrangement
  • Hold Q for a circular edit menu that adapts to audio, MIDI or the arrangement
  • Play each key switch once, then drag articulations onto their own lane
  • Align puts recorded MIDI on the grid line you meant, not the nearest one
  • Morph blends up to four effects as you drag one orb
  • Singularity turns a full finishing chain into one knob
  • Eclipse cuts the lead’s notes out of pads and strings while the lead plays
  • The video window glides aside when your mouse heads for it
  • Slipstream renders playback tracks ahead to absorb CPU spikes
  • Claude Code or Codex edit your open session through the built-in MCP server
Interactive preview: press play, click the bar ruler to move the playhead, mute and solo tracks, and search the browser. The cue and the libraries are made up.

Drag the orb. Double-click the pad to centre it.

Blend four effects with one orb

Every channel has a Morph field between insert 4 and insert 5. Load up to four effects into its slots and drag the orb across the pad. Two effects sit on a line, three on a triangle, four on a square.

The shares always add up to 100%, so the level holds while you move. All four effects keep running, and a reverb tail never cuts off halfway.

Press Write and move the orb while the music plays. Blazar Core records the path and plays the movement back.

Load one plugin into all four slots with different settings, and the orb morphs between its presets.

Hold Q for the edit menu

Hold Q and a circular menu opens at the pointer with what you can do to the selection. Point at a slice and let go.

An audio clip reverses, normalizes, shifts in pitch, fits to the nearest whole bars or inverts its polarity. A MIDI container quantizes, aligns to the click, humanizes, or bounces to audio on a new track right under it.

With nothing selected, the menu cuts or inserts time between the locators and adds audio tracks, instrument tracks and folders.

Every edit is one undo step.

Recorded MIDI that sits where you meant it

Blazar Core places recorded MIDI where you heard it, after taking off your interface’s latency. What is left is your own playing: a little ahead of the click or behind it, drifting as you go, slowly over a long take and quickly within a phrase.

Align reads that lean the way a musician would. Note by note, it works out which line of the grid each note was meant for, quarters, eighths, sixteenths or triplets, and puts it there. Unlike quantize, a note that drifted closer to the wrong line still lands on the right one. Chords land flat, and a grace note or a flam keeps its feel.

Switch on Auto and every take goes onto the click by itself when recording stops, as its own undo step. Ctrl+Z gives you the playing as it was.

Align sits beside Quantize and Humanize in the piano roll, and in the Q menu.

Drag Kontakt programs into the arrangement

The Programs tab lists every Kontakt instrument in your libraries, found through Native Instruments' own list of installed libraries. Folders adds any others.

Drag a program onto empty space. Blazar Core makes a Kontakt track, opens Kontakt and loads the program. Drop a program on a track that already has Kontakt, and the program loads there.

The track takes the program's name: the library in three capitals, then the patch. A name you typed yourself stays.

The Sounds tab does the same for the audio files in the folders you add.

Play each key switch once, then drag it where you need it

Orchestral libraries switch articulations with key switches, keys outside the playing range. Click Learn key switches in the instrument’s window and play each key switch once on your keyboard. Every key becomes a button, named by what the library’s window shows for it: Legato, Spiccato, Tremolo, Pizzicato.

A key that plays a note is left out. Blazar Core keeps the key switches with that program, so they are there the next time you load it.

In the piano roll, the buttons sit above the notes. Drag one onto the articulation lane below the notes, and the notes from there on play with that articulation until the next change. Blazar Core sends the key switches during playback.

With notes selected, a click on a button gives them that articulation. Right-click a button to rename it.

Let Claude Code or Codex work in your session

Blazar Core has a built-in MCP server. Connect Claude Code, Codex or Claude Desktop once, then ask in plain words.

  • “Double the cello line an octave up on a new track.”
  • “Put a limiter on the master.”
  • “Cut bars 17 to 20.”
  • “Export the stems.”

Your AI app reads the whole session: tracks, plugins, containers, notes, tempo changes and hit points. Changes land in the open session while you watch, and each one is a single undo step.

The Claude button in the status bar copies the setup command.

Zoom into a track and its channel

Press Z and the selected track fills most of the arrangement. At the same moment the mixer opens that channel’s strip beside it: filters, EQ, gate, compressor and tape, each with its display and knobs.

The EQ draws the channel’s spectrum under its curve while the music plays.

Select another track and the zoom follows. Press Z again and everything folds back.

Every channel has the strip built in, after its inserts and before its fader, like a console. Each module stays off until you switch it on.

Work on one track and nothing else

The Event horizon key on a track’s header leaves that track alone. The arrangement shows only that track, enlarged, with specks of light drifting above and below it. The mixer shows only its channel, zoomed, with its fader and modules.

Every control stays as it is, and nothing in the mix changes. Click the key again and all tracks come back at the height they had.

Switch on Bypass to see the strings cover the horns.

Make room for the lead

Eclipse goes on a bed, such as a string pad or a choir, and follows the lead you pick from its list. Whenever the lead plays, Eclipse cuts the exact notes it holds, and their harmonics, out of the bed. The cuts last only while those notes sound.

The horn line stays clear over thick strings, and the strings keep everything else.

Eclipse reads the lead’s notes straight from Blazar Core. There is no sidechain to route and nothing guessed from the audio.

Depth, Width and Harmonics set how deep and how wide the cuts go. Release sets how long the room stays after a note.

Finish a track with one knob

Singularity pulls a whole finishing chain into one knob. Turn it up and the track gets gentle glue compression, lows lifted, steadied and made mono below 100 Hz, cleared low mids, eased build-ups and harshness, silky highs with air on top and a wider top end.

Then a touch of tape and a soft clipper push the body up while the peaks stay where they came in. The track sounds louder and denser, not simply turned up.

There is nothing to set for the material. Singularity follows the sound’s own level, so a quiet flute and a loud drum bus get the same care. At 0% it is neutral.

The window is the knob and nothing else. The black hole of the Blazar Core mark comes alive as you turn it, and near the top of the range the jet fires.

A delay that plays the rhythm you draw

Quasar is a delay whose echoes follow a rhythm you build, instead of one note value. Click the grid and an echo appears on the nearest step, as loud as your click is high. Drag it to move it or change its level, and drag the dot beneath it to place it in the stereo field.

The rhythm runs over one or two bars at the song’s tempo and plays again, quieter by Feedback. Turn up Uncertainty and the echoes drift off their places and now and then skip a pass, so no two loops are quite alike.

Patterns has starting points, from dotted eighths and tresillo to Bo Diddley and a two-bar spiral, and Random rolls a new rhythm.

Low cut and High cut shape the echoes, and each loop comes back a little darker.

A picture window that gets out of your way

Drop a video on the arrangement and its picture opens in its own window, showing the frame at the playhead with the timecode and bar under it. Put the window on a second screen and it opens there next time.

On one screen, the picture always sat over the thing you wanted to click. Now, when the pointer heads onto the picture, the window glides off to the corner of Blazar Core furthest from the pointer. Head for Save in the top left and the picture moves to the bottom right.

Its title bar and edges still move and size it, and right after you move it, it stays put.

Frames are exact, and picture and sound line up to the sample.

Playback that rides out CPU spikes

While the song plays, Slipstream renders the tracks that are only playing back a little ahead of the audio device, on CPU threads of their own. When a plugin spikes, that time ahead absorbs the spike, instead of the spike reaching your speakers as a dropout.

Tracks you play, record or monitor, and any track whose plugin window is open, stay in real time, so a knob you turn is heard at once. Faders, pan, mute, solo, sends and volume automation stay live on every track.

How far ahead adapts by itself, deeper after a close call and back again when things are calm.

Slipstream is on by default. The audio load meter in the status line shows how far ahead it is.

Put the tracks you’re not using to sleep

Blazar Core notices instrument tracks you have left alone for ten minutes. A snowflake key appears in the top bar and gently pulses, offering to put them to sleep.

A sleeping track plays exactly as before from a rendered copy of its sound, while its instrument is unloaded and its effects rest. Their memory and CPU come free for the tracks you are working on. Fader, pan, sends and volume automation stay live.

Select a sleeping track and it wakes by itself, with its instrument loaded again as it was.

Blazar Core only ever offers. Nothing freezes by itself while you render, mix or open an effect.

Dark or Daylight, at the click of a key

The sun key at the bottom right switches the whole of Blazar Core to Daylight, warm paper and ink, at once. The moon key switches back to Dark.

In Daylight, track colours, timecode and hit points take deeper shades so they still read on the light ground. Blazar Core keeps your choice for the next launch.

See where your time went

Aevum, built into Blazar Core, keeps track of the time you spend on each session. There is nothing to start or stop.

Aevum sorts the time by what you actually do: composing, arranging, recording, choosing sounds, sound design, mixing, mastering and listening back. Only time with your hands on the keys, the mouse or a MIDI keyboard counts.

See the total for the session, each day’s sittings, and the time per channel and per bar of the song.

The time is kept in the project folder and written every half minute, whether or not you save.

Also in version 0.3.7
