I've been getting down with the Dark Star on a serious level the past couple of weeks. Synth design is amazing. The bassline in my "Work In Progress" was done on the Virus.

Loving the Arp. I've got another variation I'm playing with on the Lemur controlling some of the Arp parameters.
Any advice on beefing up the bass would be appreciated ... if you feel it's needed. Distortion, Low EQ and Sub Osc have all been used. Not sure if it should be deeper.
