Moog Taurus II

 "When I need some BIG THICK BASS I use the Taurus II. I also love feeding the audio input and letting that Moog Filter do it's magic during remixes and sound effects design. Auto Trigger & Sync for the Oscillators.. plus Attack & Decay and SUSTAIN Switch for the filter section.. don't forget portamento & Keyboard (foot pedal) Tracking..."
