I’ve been playing around with several online music generators over the last year. Mostly, they are simple timewasters to help me avoid being a productive member of society. But with the help of Audio HiJack Pro from rogueamoeba these browser sounds have made their ways into ProTools on occasion.
5. BALLDROPPINGS.com

I can’t believe that the domain name “balldroppings” wasn’t taken. They put it to the best possible use. I’ve spent way too much time trying to create the most ambient or most rhythmic sounds, and just as much time trying to get the balls to bounce exactly straight up and down or in a certain line.
4. The Indian Music Generator

This one might be a little bit racist, and not all sounds sync up in rhythm.
But in a pinch it’s a fun introduction to Indian musical elements. If you’re already familiar with Hindustani or Carnatic Music, you can go here for an online Tanpura,.
3. Tiny Drums

It looks like Q*bert would be at home using Tiny Drum 3.0 with its 3-D grid of 16 x 5 blocks.
The y-axis is a pentatonic scale for Versions 3-5. Version 1.0 and 2.0 use drum sounds.
The x-axis is a standard 16th note grid.
The tempo is adjustable, though there isn’t an option for swing or for accents. You can also save your patterns in a text file by copying the number commands (like 4369-0-21845-17681 )
2. Grotrian Piano

Similar to balldroppings, the Grotian Piano is auditory and as well as visual and relies on a gravity effect. It allows a good deal of control over 12 tones. Then it lets things get out of control in very delightful ways.
The “Grotian” setting also includes percussive piano knocks and taps.
1. Hobnox Audiotool

This one blows me away and is sure to only get better as Flash, browsers, and computers speed up. Recording is built in, the sound is amazing, and the possibilities are great. The only problem is that the learning curve is not for beginners. For musicians who want to spend some hours with Hobnox, the rewards might be something special.
