when the bass plays, the highpassed version of the pad w/ rasselbock reverb stuff plays, and when the bass isnt playing the lowpass dry version is heard.
If its not to much to ask for could you explain what you did with all the compressors, because looking at this its super confusing. plus thanks for this ive been trying to achieve this sound for some time.
it causes tone fluctuations so the reverb doesnt become ringy, that happens in AT when you have just 1 static tone, although from the HTML5 demos i think they r gonna change it, i hope so
