# LACRIMA AI

> LACRIMA AI turns a feeling into an original orchestral composition. Describe it in any language and get studio-quality 48 kHz WAV audio, multi-channel MIDI, a chord chart and Python source. You can add bass, chords, arpeggios or strings that follow an earlier piece, or start from a YouTube reference.

感情を言葉で伝えるだけで、AIがオリジナルのオーケストラ曲を作曲。高音質WAV・MIDI・コード譜を書き出し、前回の曲に合うベースやストリングスの追加、YouTube参考曲のスタイル分析にも対応。

## What it does
- Text-to-orchestra composition in any language
- 48 kHz / 24-bit WAV rendered with sampled orchestral instruments, hall reverb and mastering
- Multi-channel General MIDI export for any DAW
- Automatic chord detection and chord chart export
- Context-aware generation: add parts, continue, or make variations of an earlier piece
- YouTube reference style analysis (tempo, key, chord loop, feel, instrumentation)
- Optional in-browser audio analysis for BPM, key and bar-level chords
- Arrangement engine: 8 bass styles, 8 comping rhythms, 10 arpeggio patterns, 6 string techniques, pads

## Typical uses
- Composers and producers sketching cinematic, game, anime or video BGM ideas, then finishing them in a DAW
- Adding a bassline, chord comping, arpeggios or a string section that fits an existing chord progression
- Writing original music "in the style of" a reference track (tempo, key, harmony, feel) without copying its melody
- Learning arrangement: see detected chord charts and how each part is voiced

## Output formats

## FAQ
### Can it add a part to a piece I already made?
Yes. Each piece is saved in your browser. Turn on “Build on a previous piece”, choose “Add parts”, and ask for something like “a bass line that follows the chords”. The existing chord progression is analysed and sent to the composer.

### Can I make music in the style of a YouTube song?
Paste a YouTube URL and LACRIMA builds a style profile: tempo, key, typical chord loop, feel and instrumentation. It then writes an original melody, bass, chords, arpeggios and strings in that style. Reference audio is never downloaded, and melodies are never copied.

### How is the audio made?
Your browser renders the notes with multi-sampled orchestral instruments, then adds hall reverb, orchestral stereo seating and gentle mastering. The result is a 48 kHz / 24-bit WAV.

### Which DAWs are supported?
Any DAW that imports standard MIDI: Logic Pro, Cubase, Ableton Live, FL Studio, Studio One and more. Each instrument is on its own channel.

### How much does it cost?
Audio rendering and downloads are free. AI features use coins: a new composition costs 10 coins. Pro is ¥1,980/month and includes 300 coins every month (30 during the 3-day free trial). You can also buy coin packs, which never expire.

### Where is my history stored?
Only in this browser (localStorage). Clearing site data or switching devices removes it, so download ZIPs of pieces you want to keep.

### How do I cancel?
Cancel anytime from PayPal → Settings → Automatic payments. Cancel before the 3-day trial ends and you will not be charged; after that, ¥1,980 is billed monthly until you cancel.
