Hi,

So, in context, we can do text, and we can do graphics, and also fonts, now do we also need an interface to midi? Are you thinking about Knuth’s ĩ🛎TeX?

That is way too ambitious, maybe more like 🎹TeX (but in order to suite tex/mp extreme precision we would have to support microtones which is not in midi so that immediate abandons the project).

LilyPond supports microtones in MIDI via pitch bending; it’s not supported by all MIDI players. Maybe MOD (XM/IT) would fit better. https://en.wikipedia.org/wiki/Module_file Hraban

That is way too ambitious, maybe more like 🎹TeX (but in order to suite tex/mp extreme precision we would have to support microtones which is not in midi so that immediate abandons the project). Of course, when Mojca had ever push for 🪗TeX I'd given it a try. Too late now.

I kept misusing Lilypond for generating the MIDIs, and either Timidity (and something else that I forgot the name of, even though I think I packaged it for MacPorts) or Arduino + RPi (with some python-based synthesizer) to play them from the toy wood-laser-cut accordion. Lilypond was a good-enough approximation / similar user experience as what ConTeXt provides for typesetting text, which is why I never requested support for music in ConTeXt. A good support for \startlily c d e f \stoplily and passing the work to lilypond should be more than enough (I have an impression that I've already seen some code doing exactly that). I always used full-page scores, so I didn't really need support for short snippets either. I got stuck (read as: never took the time to finish it) at lighting up a led strip (with individually addressable colours, "neopixel"-like) at predefined places on a musical instrument to aid learning how to play new songs. (Someone who knows how to play could record a midi, then the "student" would load the midi at reduced speed and hit the keys that have been litten up.) I'm not saying that ConTeXt wouldn't be helpful in the process, but you would then ideally need some new backends for producing movies: video & audio output ;) I could surely use a metapost-drawn image of the instrument and fill the keys that need to be pressed in the video output ;) Anyway, reading midi is probably straightforward, but it really sounds like a too limited feature unless one could use video/audio output or music typesetting (which is hard enough and outside of scope of ConTeXt, I would say).

fluidsynth, I guess.

see https://wiki.contextgarden.net/LilyPond That’s what I’m using for my songbooklets. I don’t create MIDI this way, even if it would be easy, because I keep pure LilyPond files that include MIDI setup – if I copy or compose a song, it’s much easier and faster to work in Frescobaldi and compile only LilyPond. If it’s complete, I copy the melody into a ConTeXt component – not a perfekt workflow.

I always used full-page scores, so I didn't really need support for short snippets either.

Since LilyPond can create single-system PDFs, I leave page breaking to ConTeXt.

Anyway, reading midi is probably straightforward, but it really sounds like a too limited feature unless one could use video/audio output or music typesetting (which is hard enough and outside of scope of ConTeXt, I would say).

It usually makes no sense to typeset music directly from a MIDI file, there’s too much information missing (e.g. time, measures, repeats) or subject to individual interpretation. There’s midi2ly.py included with LilyPond, but it usually makes more sense to re-type the music. Hraban

Wow, that's great :) Would be nice to have it in the Garden so newcomers see what ConTeXt is able to do. Jairo El mié, 3 de feb. de 2021 a la(s) 14:00, Fabrice L (fabrice.alpha@gmail.com) escribió:

Hi,

Off topic (I hope this is ok), an animation made 100% with ConTeXt / MetaFun. Several elements in the 6 840 images are sync to the music (i.e images « react » to music - although imperfectly). Theses thousand of pages are used to make a 3m49s animation. If somebody if ever interested I can give more details of the process.

Yes, we should definitely collect links there.

Thanks a lot for your nice words ! Hans, all your covers have been very inspirational to me.. ! I use ConTeXt in my work day, and ConTeXt/Metafun to do generative work in the night ! ;-)

I usually do images ; if you or the list ever want to see more, the site https://art-aleatoire.com https://art-aleatoire.com/ is to show my work, and all you can see there is made by me using 100% MetaFun, with sometimes the help of you and the list, and all the time the help of your wonderful MetaFun manual. I’m often so much impressed by what could be done with a couples of lines of MetaFun code; life is made from DNA, art (perhaps illustrations would be a better world) could be made by the MetaFun « randomized » function.

« art-aleatoire » is french, and can be translated to « random art ». So the function I use the most in MetaFun is « randomized » !

These are beautiful! Aditya (another fan of `randomized`)

Thanks so much ! And also thanks to all the other very positive comments I had ! All welcome ! ;-)

I think I’ll come back to you about using some of your works as illustrations for our (Dreiviertelhaus’) German literature magazine.

I will be happy to contribute an illustration to the magazine !

Anyway I’d like to fill many pages of the ConTeXt journal with them.

Thanks ! Yes, I can do and article with pleasure. Just give me more indications about the level (perhaps some examples) and length of the paper.

Well, the range of level and length of articles in our (ConTeXt group’s) journal is quite big. Many of the documentation files in the distribution started as meeting talks and journal/proceedings articles.

I would be delighted and honoured to present at a ConTeXt meeting, but they are usually in Europe and I’m in Canada, so this could be really challenging.

I understand. This fall we’ll meet in Belgium again, and in 2022 in Germany. (I couldn’t afford joining a meeting overseas myself.) Maybe we could include you remotely? Last time we had “online” talks by Taco – personally is better. Hraban

OK. Maybe I could start with an article explaining the approach to do the video, highlighting problems and solutions, and then we can discuss on this ?

That would be great. Just send it to my personal address hraban@fiee.net

Why not ? ;-)

We had long discussions about online participation in the meeting. The regulars like the “intimate” atmosphere, and that doesn’t work online. We don’t want to stream anything publicly, but at least allow “known” members of the community to participate remotely. We’ll further discuss this within the CG board, I guess. Hraban
