Sortie - Mecha War Music Pack, Military Sci Fi Orchestral BGM - 44 Tracks

Sortie is a 44 track mecha war music pack for military science fiction games: 38 full looping pieces and 6 short mission cues, 42:38 of music, as OGG files with sample accurate loop tags plus all 44 editable MIDI sources. RPG Maker MV and MZ read the loop points with no plugin, and the Readme gives the import steps for Godot 4 (followed in a blank Godot 4.7.2 project, all 44 files), Unity and GameMaker. Royalty free for commercial games. Three full tracks are free to download on this page, with their MIDI.

One war from the hangar to the treaty. The base: "Sortie", "Briefing Room", "The Hangar", "Night Shift", "The Mess Hall", "Barracks at Night", "Launch Catapult", "The Ace", "The Commander" and "Colony Streets". The front: "Patrol", "The Front Line", "Combat Engaged", "Elite Squadron", "Outnumbered", "Ace Duel", "Recon", "Behind Enemy Lines", "Orbital Drop", "The Flagship" and "Fortress Assault". The loss: "Retreat", "For the Fallen", "Requiem for a Pilot", "The Occupied City", "The Enemy's Anthem", "The Captive" and "The Resistance". The turn: "Counterattack", "The Rival", "Final Battle", "The Last Ace", "Ceasefire", "The Treaty", "The Long Way Home", "Memorial", "After the War" and "Sortie (Credits)". Mission cues: "Mission Start", "Mission Complete", "Mission Failed", "Enemy Detected", "Promotion" and "Unit Lost".

One march in eight guises. The march comes 8 times on the record, 4 in D major and 4 in D minor, each at its own tempo with its own lead instrument and everything under it: "Sortie" (major, 104 BPM); "Launch Catapult" (major, 138 BPM); "For the Fallen" (minor, 66 BPM); "Requiem for a Pilot" (minor, 58 BPM); "The Occupied City" (minor, 84 BPM); "The Resistance" (minor, 120 BPM); "The Treaty" (major, 72 BPM); "The Long Way Home" (major, 92 BPM). In all eight the lead plays the same rhythm and the same scale degree note for note, 105 lead notes in each, measured in the shipped MIDI. The minor versions lower the third, sixth and seventh (136 notes across the four) and keep the seventh raised over the major dominant chord (20 notes), so a game can carry one tune from the launch to the funeral to the treaty.

The engine. In all 11 combat tracks the bass plays on every eighth note of every bar from the loop point to the end: 2088 of 2088 eighth note positions across 261 bars, measured. The combat tracks are "The Front Line", "Combat Engaged", "Elite Squadron", "Outnumbered", "Ace Duel", "Orbital Drop", "The Flagship", "Fortress Assault", "Counterattack", "Final Battle" and "The Last Ace".

One theme, one horn. The seed theme, The Line, is a dotted call up a fourth that steps back and climbs to the fifth, and all 44 tracks state it in its own shape, counted by the harness in the finished MIDI. Four more themes come with it: Fallen is the seed turned over, for the retreat, the desperate battle, the enemy anthem and the ceasefire; Sortie runs three eighths up and drops, for the hangar, the patrol and the orbital drop; Ace climbs in thirds, for the pilots and the duels; Signal opens on a held note, for the briefing, recon and the captive. The French horn plays in all 44 tracks, leading 2 of them and playing the pad, the counter line or the colour in the rest. 1,971 statements and fragments of the 5 themes across the album.

What is in it. 38 full pieces and 6 cues, 42:38 of music, 15 in aeolian, 11 in dorian, 9 in ionian, 4 in mixolydian, 3 in phrygian and 2 in lydian, 32 keys, 58 to 160 BPM, all in 4/4. 31 General MIDI instruments, among them French horn, trumpet, trombone, tuba, brass section, synth brass, strings, cello, contrabass, timpani, choir, saw and square leads, synth bass and polysynth. Every pitched note is in its track's mode or is a tone of a chord the track declares: 18,977 notes read, none outside both.

What you get. 44 OGG files, 38 of them with sample accurate LOOPSTART and LOOPLENGTH tags, which is what RPG Maker MV and MZ read; each looping file ends exactly at its loop end. 44 editable .mid sources. A Readme with per engine import notes, the proof reports, and a royalty free commercial licence.

Gate results. 788 theory checks and 510 audio checks, 0 failed, and the reports ship inside the download. They say the music is correctly written, rendered and tagged. They are not a claim about taste, which is what the free tracks are for.

Three full tracks are free on this page, with their MIDI: "Launch Catapult" and "For the Fallen", two guises of the march (the same lead in major and in minor), and "Ace Duel", a combat track with the engine under it.

An honest note. The renders are a General MIDI reference render through a conventional soundfont, and the instruments are the General MIDI sounds of those names; the MIDI is there so you can use your own. No game cue or film cue is quoted; every tune was composed for this record. The composition system is AI written code and no generative audio model is used anywhere.
