1 3xOsc for the 303 (That thing can do anything! Trust me with that one ;] ) with the camel crusher VST for the distortion. Some drums waves (pulled from a 909, 808 and 606) along with the fruity kick.
This is only a small portion of the track BTW :]
To get the squelching sound from the 3xOsc I left the filter at it's default Fast LP and 99.99% of the time I left the res at 100%. I played with the Cut-off wheel as well as the Attack and Amount wheels on the CUT envelope. Simple stuff really ^.=.^
