''In general,its an allright MIDI sequencer.Can use VST plugins,but im unsure how that works since i haven't tried that out.Nice if searching for an free MIDI sequencer,since most aren't for free.''

I have really been digging this app for the past year or so. It is primarily an android app (which is not free), but they developer also released a native windows version that is completely free.
It really reminds me of Rebirth with a lot more features. I use it to lay down beats while I'm commuting on the metro every day

In case the link is outdated by a new version, the developer usually posts the latest windows version in the front page.

Found this piece of gold when i was searching for an decent 2D animation program.
For 2D animations,this program is definetly a good choise. Only thing i wish is an option for Pixel precise editing (zooming in an area,without it altering the resolution so the points can be worked with to get an great image).

My favorites Open Source music applications:

• OpenMPT : The Best Tracker. The first tracker that I use when jumping to Module Music creation.
• Mo3 Encoder : GUI application for converting module to lossy format Mo3.
• spc2it : Simple command-line program for converting SNES music format to Impulse Tracker.
• BeRo Tracker : Tracker which has a nice MIDI to Module exporter

It seems here wasn't a link to fantastic software HourGlass by Xenakios. It's a granular synthesis studio: you open various samples, set tens of options and envelopes and play it or export to a file, or play with the app live and export a live recording! It can make great sounds if used wisely—I used it unwisely, and still got some!

Runs on Windows and OS-X (maybe Linux with Wine too?). It's stand-alone—but surely you can generate many long samples and use it in favorite sampler plugin or so.

Ardour 4.0 released for Linux and Mac OS X (and Windows beta)

The Ardour project has announced the release of Ardour 4.0. This release brings many technical improvements, as well as new features and over a thousand bug fixes. The biggest changes in this release:

- Better cross platform support. Ardour now runs on GNU/Linux, OS X and for the first time, Windows.
- JACK is no longer required, making it easier than ever for new users to get Ardour up and running (though JACK is still usable with Ardour).
- The user interface has seen a thorough overhaul, leading to a more modern and polished experience.

The Free/Demo version is gratis. It is fully-featured except that after 10min it will periodically go silent.

MusineKit

MusineKit is a software package dedicated to the practice of music and sound art. MusineKit is a tool resolutely turned towards the new digital practices.
The software grip is very fast. It can be controlled or interact with most industry interfaces (MIDI interfaces, Leap Motion, joysticks, tablet, Zil, etc.).

MisineKit is definitly a modern tool, in line with our digital practices and those of users.
This software allows anyone to create music, playing with sounds, to understand the world of sound around us and so to access the music through new technologies.

MusineKit is the result of the meeting between Sensomusic and la Muse en Circuit (national music creation center). La Muse en Circuit has extensive expertise in digital audio creation and creative music transmission practices.
Its educational work has always relied on consumer technologies and tools for live performances.

The Sensomusic company has been developing the "Usine" software for twenty years with  efficiency and reliability in mind. This offers the professional user an efficient tool for the practice of music on stage or interactive installations.

I'm not sure if this sounds as software, but Google developed a new general-purpose compression format to replace DEFLATE, and they are actually releasing it Open-Source according to some sources.

https://en.wikipedia.org/wiki/Brotli

Combined with things like FLAC and Opus, and with solid packaging of multiple modules into one block, it might be possible to create a successor to the MO3 encoder, or to host your own module archive (exclusively using lossless samples) should a certain site go down again.

What do you guys thinK?

Brotli is useless for modules. It is specifically targeted towards HTML/JavaScript compression and won't perform much better than zlib/deflate on binary data like modules. There are much better zlib replacements which Rich Geldreich discusses on his blog. In particular, BitKnit would most likely perform better than Brotli, and if you want to trade speed for size, there's of course always LZMA and its variants. I don't really think it would be worth the speed dent to use LZMA for compressing module data though, since this is by far the smallest portion of a module anyway.
There is currently simply no reason to replace a proven-to-work library (which is needed by OpenMPT anyway for existing formats) with a new library for a minimal increase in speed or size.

Oh. Well, that's a shame :/

101st reply! Lol, me.

Seriously, though, who in the world could forget the project that started Chrome?
