Serum Polysynths is a small collection of 4 soundbanks - the one of them is free.
Those four small soundbanks are sold individually. They contain classic soundind poly synth presets in a conventional way. They carry a nice nostalgic mood that makes them a nice fit when the creation of out of this epoch feeling and emotion is the desired goal in your productions.
Xfer Records Serum beside being a very contemporary and modern synth is also very capable of breath sounds of the past.
