I reckon some good instruments to try out could be tau pro, or some other 303 type emulator. I think ive come quite close to the wobbly flutlicht bassline! (as they are still me fave producers R.I.P. Reverb) I reckon its got loads to do with the compression and eq on the instrument, layering it up with another patch or two maybe, group kick and bass together and compressing again there, with other plugs on the group like possibly a maximiser to make sure its phat as me nan... also i reckon flutlicht's basslines are chorused to ****. Hope this is some help! Ive been on a mission to create that style of bassline myself since i started producing! let us know how ya get on! ;) :lol:
