Q is an interactive music software. It controls BeOS's software synthesizer through a geek's favorite interface with a lot of volume knobs and blinking LEDs, very similar to ancient analogue sequencer hardware. Turning these knobs at random, you may encounter unforeseen fantastic melodies. Try it, and have fun!
Q 0.351 is a multiple launch application like a BeBounce, properly. Some new features are added to collaborate with other instances of Q. Instructions in English and Japanese are included.
The source code of Q is available here.
