Some improvements:
* It is now possible to see the section names in the visualizer
* A new "Song Info" window that contains info about the structure and instruments in the current rendered song
* In modern browsers, compose and export midi works without logging in. The browser has to support workers, blob constructor, typed arrays and url construction (URL object). It works in new versions of Firefox and Chrome.

This is going to be a library some day. That was my main objective when I first got started with procedural music. I wanted to "solve" the music "problem" and make it reactive . I'll tell you when I have some code to share.

Do you have any more feature requests for this?

I am currently working on better tutorials.

It is very nice to be able to share code between server and client and use json "natively". Also, if you combine this with mongoDB, you get a very neat package.
Also, please check out the meteor framework for something really crazy using this combo. Made my jaw drop

The songs become public domain. You can use them for anything but you can't claim copyright. This might seem strange but the idea is that nobody should be able to use the seed "123" and then prevent anyone else from using that song/seed with their copyright.

These "terms of use" might radically change if I find some better solution.

The missing instruments seems to be solved. Darn linux flags...

I added a very simple player for browsers that support web audio (only Chrome so far I think). It can only play with one crappy, procedural instrument so far and doesn't support percussion, but this will change. The idea is that you should eventually be able to create your own procedural instruments and export to wav on the client side.

Edit: The player now supports percussion and a few procedural instruments

Also, I made the "result link" open in a new tab/window, after UprightPath's suggestion. Thanks!

I will write this in tutorial 2. Good point!

I don't know how long the server will be online. It depends on the issues that pop up

Increased that to 20 minutes just now. It felt a bit short

Ohh, almost forgot... The mp3s/OGGs are only stored 10 minutes on the server so make sure that you download them

Thanks!

The "result link" points to the generated song in the "Export" window.

You will feel limited when you want to add objects. Especially if you want to have parameterized objects in your map.

The server is temporarily online!

Abundant Music

Some known issues:

• Some mp3/ogg renders are missing instruments (they are available in the midi file so I blame the midi synth and the soundfonts ). Will look closer at this
• The tutorials and "terms of use" are WIP

In this initial stage, I might have to take the server down due to crashes etc. but I'll do my best to keep it running when I'm awake

The website is probably going online for a first test next week

I have ported the server to linux instead and feeling happy for that decision. Linux is much better and cooler for servers + it is cheaper

It is really cool that you have three games available from start in Steam for linux.

Congrats!

It is quite hilarious sometimes when they try to make names look more interesting that way. In Sweden, we also have Å (a circle above an 'a') which sounds like 'au' in 'augmented'.
In the stargate SG1 series, they added a circle above the 'a' in 'gate' which make the title sound like some funny dialect in Sweden (östgötska).

So, watch out for making your names sound really strange in other languages, even if it is just a decoration

The development is almost complete for a first test.
I used it for my music in LD25 (jam, link to post-jam version), and I found it quite sufficient. It will be available for the public during LD26 so I am discussing and thinking about server solutions at the moment

I also have a devlog at TIGSource now where I have posted some updates.
Summary of updates: Added custom harmonic rythms + optimization

I am looking forward to opening it up to the public and listen to the songs that you produce

60% funding after just 2 days, looks really promising

I think you are doing a great thing Eli!
I can imagine that this is a really fun and great learning experience.

Nice water shader!
It could be improved if you allow the specularity of the water to vary. Water gradually stops being a mirror when the angle increases. But then you might have to change the shader for rendering the terrain?

I like povray as well but I found it a bit tricky to use it as a sub-module for rendering things in windows. The runner (at that time) sometimes popped up an annoying dialog box.
I modified the code for it but then it is not ok to distribute it any longer according to the povray license.

The website looks really great!
A small comment: A bit confusing that the "Contact" and "Forum" header links switch places when you click on "Forum".

I wish you good luck with the Kickstarter!

Some more ideas of things you can do with midi/gervill with sfxs:
* doppler shift with pitch bend
* positioning with balance
* attenuation with volume
* environment effects with chorus, reverb and lp filter freq/bandwidth

If you have a channel for each sound source and manage/prioritize these depending on context, it should be a pretty straightforward coding adventure

Gervill has also an implementation of key-based tuning, which you can use (see the demos). It also has a bunch of different chorus and reverb filters that you can change with some fancy midi messages.

Box2D is of high quality but there are many ports out there of old and alpha versions of it which degrades its reputation.
I think that you can increase the quality of collision detection for fast moving objects like bullets to deal with tunneling more robustly.

This is exactly how I did with my L-system(s) . It works very well.

This book about plants/flowers and L-systems is really great:
http://algorithmicbotany.org/papers/#abop

I read that before I implemented my own L-system(s)

Is the player a point or has it some width or height? If it is a point then you can just ignore the minX, minY etc and just use playerX and playerY instead.

Is the player supposed to move in steps of whole cells or can it move a fraction of a cell? If it can just move in whole grid cells you can just perform a simple array[playerY][playerX] (with bounds checking). If it can move within fractions of cells, the player can overlap several cells at the same time. You need to check what cells that the player overlaps and then you need to know the size of the cells.

Here is some code where I assume that the level starts at position (0, 0) and the player position is at center of the player rectangle.


You also have to add some checks for not referencing something outside the array.

You don't need to specify rectangles for each cell. You just need to know the total grid size, it's start position and the number of cells in each direction. Then you can calculate all the rectangles with some very simple math.

If you assume that the player is a rectangle, it is pretty easy to check collisions within a grid. Just get the grid index from the (minX, minY) and (maxX, maxY) points for the player and iterate over those cells to check if they are occupied in your tile map.

Also, when the player moves you also want to perform several checks that the player doesn't move into an occupied cell in the next tick.
Also, if you allow diagonal movement, you would like to know if the player can move in one direction (either x or y) only to avoid that it just stops when diagonally moving into a wall.

Nice!
I get a quite steady 40fps with shadows, which is really impressive
