See Web Audio API documentation for more info. This rough demo was thrown together using the tutorial information for the API.

to play with your qwerty keyboard:

WE TYU OP ] = piano black keys
ASDFGHJKL;'<enter> = piano white keys
Q = change the waveform
<space> = lfo trigger (momentarily sets depth value to the trigger depth value)
Z = octave down
X = octave up
C = vcf freq down
V = vcf freq up
B = vcf eg range down
N = vcf eg range up

(you can also use a midi keyboard if your browser supports it)
