Recently, my brother Matt introduced me to a website called Audiotool.com - it's a web app that facilitates music creation and it includes several virtual instruments, a mixer, a multitrack sequencer/editor, and the ability to import your own sounds or samples.
I played with it for a few minutes the night he showed it to me, and then yesterday I played with it for a few hours. I didn't get super deep into the features available with Audiotool, but it's pretty intuitive and I was able to play with several of the included modules. None of the modules are directly named what they've been designed after, because of course the names are copyrighted. That said, I used a TR-808 and TR-909 (both Roland drum machines), a TB-303 (bass sequencer), and a 3-oscillator synth that seems a lot like a Minimoog. I also used a couple of reverb pedals, a distortion pedal, and two somethings. In Audiotool it's called a Tonematrix but I'm not sure the real-life thing it's modeled on, though it looks more or less like a Novation Launchpad, but with 16x16 buttons. The virtual instrument acts as a sequencer though it can also output its own notes as well which sound a bit like a marimba.
Anyway, here's what I came up with. I hope you enjoy it!
