<80s flamewar> Pah, Cakewalk? "Voyetra Sequencer Gold" for the win! :-P

Huge fan of horizontal trackers so this is very cool. If you haven’t already, strongly consider adding some simple quantization options (selecting group of notes, and quick quantize by eighth, quarter, half notes, etc.)

8mo agoHN ↗

Nice, the AI enabled Cambrian explosion of software is happening. Any idea can be built and validated in a few hours or days.

I've built something similar, but focused on guitar backing tracks. It's a TUI built using go, with midi output. Backing-tracks: https://github.com/ako/backing-tracks

Very cool, thank you for creating and sharing. Literally yesterday YouTube searched (for the first time in a long time) for "D blues backing for Harmonica". I am interested now in exploring LLM paths for that.

You did a great job on the visualizations!!

I couldn't get sound to work on OSX yet, but will keep trying. We uke here, so will make an issue for that ;)

I work on NTCharts and also just yesterday had an LLM fix a visual bug using world understanding, one that I had thought about multiple times prior. In the end, the solution was obvious once revealed and I had overthought the problem.

Video in OP Miditui project is amazing, I missed it on first skim.

Thanks, everything was vibe coded, so visualizations thanks to vibe coding. I'm prompting like key user/product manager/architect, so expressing user needs, and ensuring the overall architecture seems reasonable.

For uke, would you expect same functionality but with 4 strings?

8mo agoHN ↗

Validated? TUI-based sequencers have been around since the 80s.

It's nice that someone can vibecode what used to take probably a manyear of work though.

8mo agoHN ↗

Not the generic concept of TUI sequencers (i know, have used sequencers on c64), but any weird slightly different idea.

In my case i wanted flexible way to display lyrics, chords, strumming, metronome, fingerpicking, scales, chord shapes, etc, with an easy way for LLMs to define the backing-track, so a backing track DSL.

I think we'll see a lot of these very specialized software popping up, instead of generic solutions that contain everything and the kitchen-sink, where you don't use 90% of the functionality.

8mo agoHN ↗

Any idea can be built and validated in a few hours or days.

Let's not oversell it to that degree, please.

The amount of ideas that can be built and validated within a few hours or days went way way way up, but is still very very far away from "any". Nor will it ever get there unless we get actual AGI with "free" compute.

8mo agoHN ↗

What a weird coincidence. Literally today I started building a fully keyboard driven MIDI sequencer in Rust. I was originally going to build it as a TUI but then decided against it because I wanted to have more control over the UI, so I'm building it as a pseudo-TUI with Bevy. But the idea is very similar, I'm approaching this project as a "vim"-like editor but for MIDI editing.

8mo agoHN ↗

Really nice! Reminds me of my "Voyetra Sequencer Plus Gold" which I still have running on a 286, because it has great midi timing! "Miditui" would need a descent recording feature besides easy keyboard roll editing, quantization and so. Any plans to implement this? So you actually could compose music with your real midi devices.

8mo agoHN ↗

I clicked only because I'm interested in doing a project related to MIDI, so I was surprised to immediately see that this project was built with Claude Code and unlike, most AI-assisted projects, includes the prompts. Skimming the comments here it appears most people have not noticed this. I suggest re-submitting this project again but with a headline that promotes it as a demonstration for vibe coding.

8mo agoHN ↗

There really isn't a good way to put a note to those prompts in a headline (putting "I vibecoded this" would just get it flagged). I'll likely do a blog post discussing the prompt process at some point.
