Most parameter combinations in synthesizers sound like shit.
That flexibility is what makes new sounds possible.
But if we release a neural synthesizer and one prompt doesn’t sound as you expect, you’ll be mad at us.
So we’ll just keep the new neural synthesizers to ourselves.

The ACE-Step 1.5 paper can be confusing.
In this post I share are its main ideas: artintech.substack.com/p/ace-step-1...
1. DIFFUSION MODEL: supports multiple tasks.
2. LANGUAGE MODEL: reprompting & semantic tokens generation.
3. DATA PREPARATION: 27M songs.
4. OPEN WEIGHTS: supports LoRAs.

The future of AI music won’t shape itself. It’s up to us to imagine what it can become.
If its current state feels like ‘slop,’ consider creating something different yourself.
While this essay has focused on Interactive AI Music, I’m sure there’s still much more to discover.

AI art is criticized for feeling soulless, lacking relatability and human narrative.
But AI art does not need to be like that.
I strongly believe that AI can be used to create art that was previously impossible and that it will be equally appealing as previous art forms.

The key issue in AI art is agency. We need workflows that produce art that clearly feels like it’s from the artist.

Lately I’ve been meeting many AI musicians.
I enjoy that first day when I don’t yet grasp their artistic practice or fully follow what they say.
But as we interact, our language becomes similar. Especially in how we refer to concepts/ideas.
I’m not sure if that’s good or bad.

AI should be used to create art in ways that are both ethical and compelling.
Ethics are important, but being compelling is just as important. If it isn’t, there’s little reason to use AI for artistic creation.

I would modulate that by saying that it's possible to create AI art that draws attention to its process, mechanics and biases - its artefacts and politics. But I think you probably agree with that already, there just aren't enough characters in posts to say it all in one.

Repetition is a human invention.
Nature rarely repeats itself.
Yet, we play the same music and films over and over.
Generative art changes every time you experience it.
What if generative AI ends up feeling more NATURAL than the static media of today?

Got the Pixel—the AI is built-in and great.
I don't understand the need for separate AI devices.
Maybe glasses could work to help our posture, but having a camera on your face is awkward.
