## What is YouCompose?

Meet Aimée, your AI assistant composer, ready to help you create amazing music effortlessly.

Aimée: Originality You Can Trust.

In the evolving landscape of artificial intelligence and creativity, concerns about originality and copyright are paramount. Aimée, the AI-powered assistant in YouCompose, stands out by ensuring that the music she helps you create is entirely original and free from copyright issues.

Aimée Doesn't Steal!

Aimée's AI isn't trained on existing musical data. Instead, she generates her own unique musical content. This innovation is achieved through the clever use of an expert system that combines music theory with advanced genetic algorithms. As a result, Aimée produces truly original compositions that are not based on or derived from existing works.

At the heart of Aimée's originality is an expert system grounded in comprehensive musical theoretical data. This system provides Aimée with a deep understanding of music, enabling her to compose with creativity and precision. Whether you're crafting a symphony or a simple melody, Aimée applies her theoretical knowledge to ensure your music is harmonically rich and structurally sound.

Aimée also leverages genetic algorithms, which allow her to evolve and refine musical ideas through a process akin to natural selection. By iteratively improving upon initial ideas, Aimée can explore a vast space of musical possibilities, generating compositions that are both innovative and musically coherent.

This approach is crucial in addressing potential copyright infringements. By not relying on pre-existing musical data, Aimée ensures that the music you create with her assistance is genuinely yours.

Why Originality Matters?

In the realm of music composition, originality is not just a matter of artistic integrity but also a legal necessity. Copyright infringement can lead to significant legal challenges and financial liabilities. Aimée's ability to create original music provides peace of mind, allowing you to focus on your creative process without worrying about potential legal repercussions.

### 2/5 — MIDI Failure

*2026-04-09, version 9.17*

This app has such potential, but each time I try to load a MIDI file, it only loads one instrument part - and even then, it doesn’t sound anything like the original. I got this to work with my MIDI files which is not doable at the moment.

### 5/5 — Awesome helper!

*2023-12-31, version 8.22*

This is a great app!  A major boost to one’s creativity.  I’ve been eyeing this app for a while and finally decided to check it out and i am pleasantly surprised by all the features and capabilities.  It is very simple and yet gives you so much room to experiment.  MIDI connectivity is great and the selection of in app instruments is great!  It won’t necessarily compose for you but it will do most of the work and leaves you in control of your sketches.  Great for composing something beyond the mundane.  A cherry on top of your inspiration.

### 5/5 — Awesome !!!

*2023-01-06, version 7.21*

Fantastic app, thank you very much !

### 1/5 — Deleting a song ?

*2022-03-04, version 5.17*

That’ll stop ww3 from igniting 
And deleting your app from half its users

### 1/5 — Plante à l’ouverture

*2022-02-21, version 5.16*

Inutilisable

### 5/5 — Full of Surprises - coremidi? Inter App Audio? Yup! Ignore low raters

*2021-11-06, version 5.16*

Low Raters, I’ll deal with you later in the review… Starting with the cheerful and clever tutorial, this app surprised and delighted me. I’m not a trained composer but this app made me want to be one. I think the devs and creative minds behind this gem need to be recognized as a real rarity these days - quality for quality’s sake. Bravo! ———— ————- ————- To all the confused reviewers who want this to be better than Cubase and Sibelius combined # or the reviewer who’s big complaint was that this software couldnt possibly be used because there’s not a $6,000 full multisampled orchestra included - have some perspective and recognize the cost of this app in comparison. I imagine you are the kind of person who regularly gives Uber drivers 3 stars or rarely tips more than 15% at restaurants. You understand it’s not like a movie rating, right? It’s pass/fail. After a certain number of non-5-star ratings, the app starts to suffer. Just like Uber drivers. Sorry, rant over.

### 5/5 — iOS 14 problem!!!

*2020-09-19, version 5.14*

Update please

### 5/5 — De loin la meilleure aide à la composition sur le marché

*2020-05-14, version 5.14*

Une aide précieuse pour aider à solutionner un problème ou à l’aborder sous un angle différent. Cette application mérite beaucoup plus de reconnaissance, et surtout ses développeurs. C’est vraiment très intelligent.

### 4/5 — Yo

*2020-04-15, version 5.14*

Se cierra actualizan porfavor y si fuera posible exportar xml gracias.

### 3/5 — Very Interesting, Needs More Tools

*2019-10-28, version 4.25*

I really love the idea of this app, but it needs better note drawing tools in piano roll midi note drawing and modification. It also needs to save the settings you make when writing original melodies. Currently, if you delete the melody, it resets the settings. It also really needs a count in when playing a melody live. In fact, I would really like to see an implementation for melody loops to go beyond a single bar.
