My co-founder and I have spent the past while building Ivory (https://ivory-app.com), a tool for converting piano recordings into editable notation, and I wanted to introduce it here because this community is exactly who we built it for: people who compose at the keyboard.

The problem we set out to address is a practical one. Composers who work at the piano routinely capture ideas as audio , a phone recording, a quick DAW take , and then face the slow task of transcribing their own playing by ear before they can develop the material. Manual transcription of dense voicings, fast passagework, or pedalled textures can take longer than writing the piece itself.

Ivory is built specifically for that step.

What it does

• Converts a piano recording (MP3 or similar) into notation in the browser : nothing to install.

• Uses a model trained specifically for piano, rather than a general-purpose audio-to-MIDI converter.

• Produces editable output, exportable to MusicXML (Sibelius, MuseScore, Dorico), MIDI (any DAW), and PDF.

The intended workflow: record an idea, transcribe it in Ivory, then export to your notation software or DAW and compose from a working draft rather than a blank page.

Why we focused on piano Piano is one of the harder instruments to transcribe automatically: overlapping voices, sustain pedal blurring note boundaries, fast runs, and up to ten simultaneous notes. General-purpose tools tend to struggle with exactly these cases. By narrowing the scope to piano, we handle chords, fast runs, and pedalling considerably better than the broader tools we benchmarked against.

Honest limitations

• Piano-focused , not intended for full multi-instrument or orchestral arrangements.

• The output is a first draft; expect to correct some rhythms, re-bar passages, and make voicing/enharmonic decisions yourself.

• Free tier is capped at one minute of audio per transcription (unlimited number of transcriptions) , enough to evaluate properly on real material.

We would genuinely value feedback from composers here, both on transcription quality and on how it fits your existing notation workflow. Happy to answer questions in this thread.

The matrix is:

[0,2,9,3,7,11,4,8,10,1,5,6]

It's based on, Webern's Symphony, which has no transformations according to my theory of matrix modulation. It moves at 30 BPM, and follows Mason's rules of composition, albeit serialism, at that tempo.

Attached is a complete analysis of the numbers. You can tell, according to the galactic harmonics, how much thought was put into that matrix. I Joke. However, looking at the analysis, there are some interesting inferences:

64. GALACTIC FREQUENCY ANALYSIS ▸ COSMIC ACOUSTIC SIGNATURES

Milky Way Frequency Drift....... 0.9305

Andromeda Collision Sonic Reflection 0.5836

Dark Matter Interaction Tone.... 0.2100

Supernova Remnant Frequency Mapping 0.3495

Pulsar Waveform Analysis........ 0.9389 Black Hole Sonata............... 1.0000

Neutron Star Collision Harmonics 0.2377

Galactic Echo Sonification...... 0.6505

This is what I'm jamming on now. It's said that we are composing the very thing that the universe's materials encompass. It's only fair to analyze it as such, too. I mean, we don't have to agree - there is room for independence in what I have to offer in the website.

So, what do the numbers mean? Numbers, are often static. When paired with music, the numbers become realized through motion. In this case, as each number permeates through a representation of music, the numbers become more viable. That's expensive to convey, and data intensive; I guess it just means that the numbers are a symphonic glade of information that is easier to ingest than learning about it.

I hope it sounds good, in any case.

Based on the acoustic signatures, I can conclude that there is a weak correlation to Dark Matter, but there is a strong correlation to Pulsar Waveform Analysis. I do like the idea of Galactic Echo Sonification, in my music too. I hope you have fun with the website, empowering your music, too.

Other than that, the chorus was botched to good effect, read as the melody after a vowel chant.  In effect, AI made a new chorus.  Overall, the song is represented well, and I am happy with that.

Enjoy!

Jesus Was Born this Day_Harper.mid Jesus Was Born on this Day (David Harper) - MSMT.mid

Молчи, скрывайся и таи И чувства и мечты свои

Пускай в душевной глубине Встают и заходят оне Безмолвно, как звезды в ночи

Любуйся ими

и молчи. Как сердцу высказать себя Другому?

Как понять тебя?

Поймет ли он, чем ты живешь?

Мысль изреченная есть ложь; Взрывая, возмутишь ключи

Питайся ими

и молчи. Лишь жить в себе самом умей

Есть целый мир в душе твоей Таинственно‑волшебных дум;

Их оглушит наружный шум, Дневные разгонят лучи

Внимай их пенью

и молчи…

Tons of effort went into this song. It began with a piano performance by, Guqi. Before that, I composed the song in agnostic silence; my apartment was completely taken from me while I was in the hospital. I should have reacted 'appropriately' and fought the person that took my apartment, but instead I wrote this song.

It's my first atonal fugue. I wrote the fugue pen to paper, while my apartment was gone right there, on the spot. I gathered my thoughts, and composed the notes in order as each emotion struck my heart.

Anyway, the form is subtle. It's ABA' and the chords are the numbered set stemming from [0, 4, 6, 11] modulated in a simple way. But for brevety, you could use my website:

ATONAL FUGUE

The website will set you off on a compositional journey where the notes spiral. Try it.

Compositionally, the song was written with intense conviction of the notes rotating while each chord turns them. It's hard to recall, but if you could just sit in a room, pen with paper, and a candle; all to write music. Do it.

My 2nd submission titled “Glory to God”

I wrote the lyrics and included bible verses. The song is about God’s goodness and the reason for the season.

I used AI, so if you don’t like AI, just don’t listen to it or make any comments on my post. Thanks!

Suno is a blessing, I can go make a lot of music faster and reach people with the word of God in all musical genres. 

Christmas is about the Lord Jesus and our mission is to spread the gospel. We can use AI for good or bad, let’s all leave a trail for the lost souls to reach heaven.

My submission, if you don’t have spotify ill put the file in too
