1.Go to google translate (http://translate.google.com)
2. Set both languages to german
3. copy and paste this (more on how to create your own beatbox in a bit)
"pv zk pv pv zk pv zk kz zk pv pv pv zk pv zk zk pzk pzk pvzkpkzvpvzk kkkkkk bsch"
4. If it worked then a button called beatbox should appear
To create your own beats heres a quick little key:
zk = suspended cymbal
bschk = snare
pv = brush
bk = bass
tk = flam1
vk = roll tap
kt = flam2
kttp = flam tap
krp = hi hat tap
pv = short roll
th = better hi hat
thp, ds = instant rimshot.
