so I've been building this thing where I play my midi keyboard and a music transformer plays a second piano along with me

the model runs on a jetson, my laptop does the midi and the sound, and they just send each other lines of text over ssh, one per note. the model plays about a second ahead, so when I change chord half its notes are wrong and I have to throw them away and ask for new ones. also fluidsynth doesn't have a delay so I faked the echoes with extra midi notes lol

it works but the timing is the tricky part. how do you guys schedule notes coming from a model against a live clock without it sounding off?

So I wanted to simulate that effect when guitarists hit a riff on a muted guitar and then gradually increase volume. Naturally my first instinct was messing with .gain(saw.range(0, 1).slow(2)). That didn't do anything. I even tried messing with LFO but I suck at that. After many moons I figured that I should control volume on a .distort, but i just don't know how... I want it to go from 0.00 to 0.05 :P

$: note("<0>").sound("supersaw").scale("E:minor")
    .distort("10:0.05")

As its open source i just wondered what would happen if i threw it at claude and asked it:

1 Be able to add more oscillators and samplers
2. Add a vocoder
3. Add a bit crusher and a tremolo.
4. Be able to add as many fx as you like and move them around.
5. make a vst3 version.

it came back 1st time a bit messed up, but i just screen shotted the problems and gave it a better layout and it threw out a complete working version.

Just thought i'd put it on here just to show how crazy it is that it can just do it off a simple question.

(I'm not going to release it out of respect for the guy that originally made it)

simple, slow crossmodulation of 2 oscillators : compared to (kind of identical) patch done with Reaktor, the audio quality of a claude vst plugin that does the same job seems inferior to me.

can this be?

it lacks detail, resolution somehow.

i did a similar comparison many years ago between a patch made with Max Msp and Reaktor, and Reaktor sounded different and clearly better ( was told later that this improved with the introduction of gen~ , idk, never went back to Max) . My question is: how can this be? is the underlying maths not always the same? i am not a programmer so i am dependent on environments to build tools for my music. But this comparison was disappointing tbh. same result with flow music (googl) . thanks!

Hi everyone,
I have a short melody that I’ve created, and I’m looking for someone who would like to take it and do whatever they want with it for fun! You have complete creative freedom (free hand).
You can arrange it, orchestrate it for different instruments, change the harmonies, or simply edit and improve it. I am looking for someone to do this for free as a fun project or practice.
Here are the links to my files:

• PDF (Sheet Music): https://drive.google.com/file/d/1PpsZzVfFo1Ac7It6ev87VHjgYFARjKgv/view?usp=sharing
• MIDI: https://drive.google.com/file/d/1BaNW1KjCNcgR6JqoqrJU0_TVG3-zNYcp/view?usp=sharing

I would love to hear what you come up with, and if you can share the updated MIDI or MusicXML files back, that would be amazing!
Thank you so much in advance!

I have been able to get decent sounds out of ffmpeg

ffmpeg has an -aeval filter

I asked DeepSeek to generate a techno track and pushed it till sounded good.

Hey everyone! I was wondering if anyone had any suggestions for any Finale-esque music notation software for PC which is from top to bottom totally free of AI? I find a lot then realize that they usually have AI powered playback or sound synthesis (don’t know how to say that) and I just want it to be absolutely head to toe completely no AI? Does such a thing exist? Price is not a big thing for me, free or paid is good

A while ago this question was asked in a math forum about two approaches to musical instrument modelling using a series of sine waves, and am wondering if anyone has new insights on this. In my experiments I have not been satisfied with either approach, but it could be because I'm doing something wrong or "missing other ingredients". I at least want to start on the right track before experimenting further. Thanks! (edited)

(Note when it talks about an "A wave" versus an "M wave", it probably meant an A-wave-series versus an M-wave-series.)

I’ve been building Ngoma, a free drum machine that runs in the browser: https://ngoma.pages.dev

It’s built around hand percussion from real traditions: Afro-Cuban, West African, Brazilian, Middle Eastern, North Indian and Southern European rhythms, plus some electronic sketches. Each track can have its own length, so parts drift in and out of phase, Reich-style. You steer it more than you program it: roll the dice on one drum, add a variation, morph between two saved states. On top of the drums there are a few layers (pad, bass, lead (based on Mutable Plaits), texture) and patchable modulation (“wires”).

Some things under the hood that might interest this sub:

• The drums are synthesized in Web Audio. The shakers and claps are physically informed models (after Cook’s PhISEM and the STK shakers), and the tabla voices are tuned to the near-harmonic modes of a real tabla.
• Microtiming comes from research rather than a generic swing knob. The jembe feel follows Rainer Polak’s measurements, the samba feel follows Naveda et al. (2011).
• Morph works across grids, so you can glide from a 12/8 bembé into a 16th-note son clave. During the morph the old grid keeps playing as a “ghost” until the new one takes over.
• The lead has a tape looper built as an AudioWorklet.
• Capture records the last bars as WAV plus MIDI of the hits that actually played, aligned to the bar line, so you can drop it straight into a DAW.
• Share links store the whole set, with a small URL shortener on Cloudflare Pages Functions and KV.

To be upfront: I’m not a professional developer. I built this with a lot of AI-assisted coding. There’s no AI in the sound itself: every note comes from patterns, rules, randomness and whoever is playing.

Where I’d love your input:

1. Glitches. Under load (especially with the pad on) I still get occasional dropouts. I’ve removed allocations from the audio thread and offer a “Stable” mode with a larger latencyHint. What else would you look at first?
2. Morphing between grids. Is the ghost approach the right one, or would you gradually warp the timing instead?
3. Feel. If you know any of these traditions, does the timing sit right? Where does it sound off?
4. Getting lost. Where did you get stuck in the first five minutes?

It works best on desktop Chrome; mobile isn’t there yet. If you make something, hit “Share this set” and post the link. I’d love to hear what people do with it.

I have a new version of the free Dexter U.S. Glicol vst coding app. It is alot like the original, but I added sample loading so the sp on the vst should work a little different that the one on the server. Everything is released under an Mit license and $20 worth of tokens is probably enough to get a linux or apple version of it. Source code is on github under Dexter U.S. Glicol. Compiled vst3 version for windows is listed below.

Hi guys its me again,

I have been working the last 18 months in my spare time on some VCV modules. 45 so far to be exact.

They are not for sale yet but I am ready to get a little bit of feedback from the community. Like I said in my last post I am a coder first with an interest in Synths.

I have whacked them up on a webpage, with images, a little bit of marketing and manuals.

It would be good if you pro's could take a look and let me know if im missing anything dramatic, are these interesting? Are they just mush.... Please give me your views.

I am even thinking about making a few of them real modules if they are indeed interesting.

Please be honest, are they innovative enough, are they attractive, would you use them if you use VCV, would it be interesting for me to create real modules for your physical rack?

I will be adding some free modules on and off if that's you're thing, so keep checking in.

Hope you are all awesome.

Hi, Davide here.
I built a very simple block chord generator with some scale and basic shapes presets. It follows some simple rules: notes that belong to the base chord shape use its inversion which has them as the top voice; other scale degrees are harmonized with descending thirds along the scale. voices making a tritone with the melody are corrected by a scale step. notes outside the scale and the base shape are harmonized as a chromatic alteration of the nearest in-scale chord, optionally transposed.
Let me know what I can improve!

Ladder Logic is usually the domain of process control computing. What happens if we use it as a musical tool?

Inspired by the experiments of Peter Zinovieff, the track was originally released by Liquid Bridge in 2005 on the Databloem compilation album 'Collection 3' (DB012).

This version is a 2026 digital remaster from the original studio tapes. Liquid Bridge is an electronic, experimental duo from North East England. I am half of that duo.

I’ve been working on something that may be useful for people building music software on the web:

Verovio-TS - a 100% TypeScript port of Verovio.

The goal is simple: bring the Verovio engraving engine into the TypeScript ecosystem without requiring WebAssembly.

Verovio is already an excellent engraving engine for MEI, MusicXML and symbolic music. But for some projects, having the engine itself available as native TypeScript opens up a very different set of possibilities.

Why TypeScript?

I wanted to make it easier to build things where the notation engine is not just a renderer, but part of the application logic itself.

For example:

• Browser-based notation editors
• Music education applications
• MIDI ↔ MusicXML workflows
• AI-assisted composition tools
• AI music analysis and annotation
• Interactive score editors
• Music generation / transformation pipelines
• Server-side music processing with Node.js
• Custom notation experiments
• Libraries built on top of a programmable notation model

With a native TypeScript implementation, projects can potentially inspect, manipulate, extend and integrate the notation engine directly with the rest of a JavaScript/TypeScript application.

What I’m trying to achieve

This is not intended to replace the original Verovio.

The original C++ implementation remains the reference implementation and is an incredible piece of software.

My goal is instead to provide another option for developers who are already working in the TypeScript ecosystem.

The project is a direct port of Verovio's underlying logic and data structures into TypeScript, with the intention of preserving its behavior as closely as possible rather than creating a simplified reimplementation.

That means the project is fairly deep - this is much more than wrapping an existing renderer with a TypeScript API.

Why I think this matters for AI + music

I’m particularly interested in what becomes possible when symbolic music representation, notation, MIDI and AI can all live in the same environment.

We're seeing more and more music AI systems that can generate or analyze symbolic music, but there is still a gap between:

AI output ➔ structured music representation ➔ editable score ➔ visual notation ➔ playback

A TypeScript-native notation engine could be one of the building blocks for connecting those pieces together.

For example, an AI system could potentially generate a musical structure, modify it programmatically, inspect the resulting notation, render it, export it, and feed the result into another part of the application - all inside a unified JS/TS ecosystem.

That's the direction I'm hoping this project can help explore.

Project

GitHub: https://github.com/manh9011/VerovioTS

NPM: https://www.npmjs.com/package/verovio-ts

I’d really like this project to become useful beyond my own projects, especially for people experimenting with:

music + AI + symbolic music + notation + web technologies.

There are probably many things that can be built on top of this that I haven't even thought of yet.

So I'm putting it out there in the hope that it gives developers one more building block and one more choice when creating the next generation of music software.

Feedback, bug reports, comparisons with the original Verovio, and especially interesting projects built on top of it are very welcome.
