Well, it’s about time I released another application right? If anyone has ever played Bloom on the iphone, I’m sure you’ll recognize my port from iphone to table.

If you’re not familiar with bloom, it’s a very simple music creation application. Press anywhere on the screen to create circles that grow and ‘bloom.’ As they fade out and re-appear, they play a note. The note is based on the x-axis. As you move right, the notes go higher.

Click the above image to play

How to use:

-Press on screen (mouse, touch, multi-touch)
-Rollover/touch/click already created circles to remove them and their sound
-Press the upper left ‘clear’ button to clear all circles and sounds on screen.

The source folder should include everything you need to run the application. You don’t need to copy anything into your current AS3 directory. I’ve commented the Main.as file very well and it should give a good look into making simple applications with the AS3 Touch API.

Thanks to Christian for the background color tweening effect.

New video of the new system that loads and unloads applications. Also, the desktop is now sending out OSC message to PureData to create some sounds based on finger number and position on screen.

No, I haven’t forgotten about the other programs that I first started on. I’m still developing Audioshape Sequencer as well as Musical Squares, but recently I have made some big changes/additions to the MuliKey application. I think all of the changes are great improvements and will allows for much more functionality and experimentation within a simple application like MultiKey.

First, if you’ve seen the first versions, you’ll notice that the look has changed slightly. I’ve gotten rid of the background (for now) to allow for best performance. Also the border of the keyboard has changed a bit so that it is easier to resize the keyboard. Previously the border width made it somewhat hard to select the keyboard for moving, rotating and scaling. I think the little circle ends will help with selection.

You’ll also notice a tab on top of the keyboard that didn’t used to be there. This tab is a control unit. Click on the tab and controls will pop out. On previous versions, when a key was pressed the note would play until it hit the end of the sound file. Now, when a note is pressed, the note will end when the key is released. With the control center, you can control how notes start (Attack time), how they are released (Release time) , and their sustain amplitude (Volume). It is similar to an ASR or ADSR without the Decay (for those that are familiar with audio envelopes). There is also a control for switching between a few different sound libraries (synth keyboard, violin, overdrive guitar, and percussion) .

Also, now you can move, scale, and rotate the canvas (black space).

For those that don’t have a multitouch table, this application, for the most part, will now work with a mouse! It’s single “touch” this way, but you can get a general idea of how everything works, although it will be much more natural with multitouch interaction.

I feel these are some really great improvements, but I welcome any suggestions or ideas you may have. Feel free to throw out any ideas in the comment box and comment how you feel about the application.

*Note: I’m including a .swf, .exe (for windows), and .app (for mac). Make sure to set the security settings so you’re able to connect to FLOSC if you’re using this with a multitouch table.

I finally have everything up and running decently enough to make some videos. So here’s a couple videos of the software I’m currently working on. I combined both the multiKey and Musical Squares applications into one canvas. A user can move the canvas, or the individual applications around, rotate, resize them as well as some subtle extras.

Enjoy! Hopefully I’ll have some better quality videos up soon.

MultiKey is a simple multi-user, multi-touch music application. In the standard version, there are two music keyboards. One is a full octave, while the other is two full octaves. By pressing on the white border, the individual keyboard will switch into move/rotate/scale mode and can be rotated and resized to your liking. Press on the white border again, and move/rotate/scale will be turned off. Have fun!

MultiKey v1.3

Possible Future Changes/Additions/Bug Fixes:

-Ability to change to different sound library
-Ability to add (drag out) multiple keyboards. Idea: use a gesture that is assigned to keyboard creation.
-Add some kind of dynamic movement in background when key is pressed since keys are transparent.
-Fix canvas and create ZUI so pianos don’t fly off of screen range.

How it Works:

1) Start FLOSC,
2) Open Touchlib OSC.exe,
3) Start up the application (exe or swf).

If you would like a different set of keyboard sounds. Replace the mp3 files with your own. Rename them to the same as in the folder. A = A natual, As = A sharp etc.

If you have comments, would like certain features added or would like to add them yourself, please comment below. I will also add them to the “Possible Future Changes/Additions” section. Thanks and have fun playing!
