Bass Station II. Here's what they had to say:
"Bass Station II is an analogue mono-synth based on the classic original Bass Station but re-worked for the 21st century. It has two filters, two oscillators plus a third sub-oscillator, patch save and a fully analogue effects section. Add a step sequencer, arpeggiator, full sized keys and a powerful modulation section and you have the makings of a synth that is built for bass, but capable of so much more."
