Fwd: Re: Creation of a community on Qt for art software : Creative Cuties
be at mixxx.org

Hi Krita developers,
I am one of the developers of Mixxx, the free DJ software. We recently
got this invitation to organize with other developers of free artistic
software using Qt. I thought I'd pass this along if you're interested.

This is very likely of interest to the Mixxx community. I posted this on
our Zulip chat. <https://mixxx.zulipchat.com/>

it seems that the Discord link had an expiration date which I forgot
Here is an unlimited one : https://discord.gg/wJdQ6sS
Apologies for the annoyance.
I also created a #creativecuties channel on freenode, which will in time
be linked with the discord channel unless we find a better way of
All the best,

You are invited :-)
You are receiving this mail as you are likely to be part or know
persons who may be part of the development team of a software
which fulfills the following criterions :
- It is free software.
- It is developed with the Qt framework.
- It is a software mainly used by artists & creators - visual
arts, music, lighting, stage control, creative coding, video...
This mail is addressed mostly to individuals as it's easier to
find out, but can (should) be discussed with the dev team of the
organization you are affiliated with,
and shared with any person or project that may be interested in
As you all know, developing with Qt is some days very nice, and
some days very... not nice :-)
In order to improve on this, I am trying to organize a
conference / meetup / community which would be centered
specifically around the use of Qt for software targeting artists
as end users.
The reason for that scope limitation being, that we often have
fairly similar problems to solve across different software in
that field, especially as OSS devs :
allow users to make extensions & plugins
- Rendering nice graphics with the GPU
- Handling real-time operation for audio
- Communicating with various kind of hardware through various
uncommon protocols / drivers
- Creating custom widgets used in art contexts - color choosers
of various kinds, knobs, vumeters, waveforms, etc etc
- Interoperating with web through websockets, for instance for
remote control apps & similar.
- Creating timelines & similar kind of complex widgets with
complex user interactions
- Building & testing for platforms we don't own (e.g. most
likely an overpriced intel and soon-to-be ARM CPU in a metal
chassis with a half-eaten fruit on it)
- Theming, skinning - art makers sure do love their dark themes
& skeuomorphic UIs :-p
The central idea for this meetup would be to create a space
where we could share knowledge around these topics, and discuss
which solution experimentally works best, what pitfalls are
encountered, etc. as it's not unlikely that for any of these
problems, someone else in that community would already have
encountered it in some way.
The second idea is to identify the Qt shortcomings, and work
together either on fixing them in Qt (as it is often the most
future-proof way) or provide potential alternative libraries /
ways of doing things. (or just complain very loudly on the
mailing lists or bugreports :-p).
A first thing to do would be to create a kind of community space
to discuss a few points - this can be this mail chain at first
but I think that using a chat platform such as Mattermost,
Slack, Discord, RocketChat, Zulip, or IRC channel of some kind
would be better.
These few points are for now :
1/ What would be the meetup format ? In an ideal world we'd do a
conference with a nice hackathon and lots of pizzas :-)
but it's more likely that things would look like an online
meetup soon. Any idea would be appreciated - other than that
things could start as soon as mid-september for instance if we
are to do something over a video conferencing service.
2/ Should this only be about free software, or should we also
invite proprietary software developers ?
I am thinking of Blackmagic, Allegorithmic, Arobas, VIDVOX and a
For now I've created the following Discord instance to discuss:
https://discord.gg/n2TCrR - any other idea is appreciated, as
long as everyone can get on board :-)
The meetup would follow the Berlin code of conduct
(https://berlincodeofconduct.org/) ; it is important to me to
ensure that we encourage diversity among the attendants, and all
have a nice time overall.
To finish, here's a few words about me: Jean-Michaël Celerier.
I've been working on a sequencer for live show control, ossia
score (https://ossia.io) since 2014, using Qt5 & mostly C++.
I've worked at KDAB (a company fairly involved in Qt
development) from 2019 until now where I can afford to work
full-time on my project.
Also, I like organizing things and I love art and making
artists' lives better, with free software :-)
I live in France, and am affiliated with the Université de
Bordeaux and the SCRIME (Research and Creation Studio for
Computer Science and Experimental Music).
I can easily have access to a conference space if we are to
organize something in the physical world.
Hoping to hear from you all soon.
