Korg has just announced three brand new mini-synthesizers in which each are all under $150. The Volca series consists of the Volca Keys lead synthesizer, the Volca Bass synthesizer and the Volca Beats rhythm Machine. While most companies take their premium product and work down in order to make cheaper versions, Korg seems to take a different approach.
