The sound and usability is enhanced. NoiseMaker has two oscillators en one sub oscillator. The synth now has effects (reverb, chorus and a bit crusher), a ring modulator, an enhanced amp envelope (ADSR) and new filters. The 128 presets give a good impression of the sounds you can make with this vst instrument.
Patrick Kunz of Togu Audio Line (TAL) is the maker of some great vst plugins, which he made available for free to the vst community. If you use his plugins a lot you might consider to give him a donation by PayPal. A personal favorite for great basses is the user friendly TAL-BassLine synthesizer, inspired by the analogue Roland SH-101 hardware synthesizer.
