Nice music samples. Well developed. To low quality equipment for about 230,-. Good feedback about possible use. Unique device. Not high tech & matterials. Every electro or electromagnetic puls, could be translated into music. I really thought compared to the outcome, that for that price, more would & is be possible. Understandable cause of patent. Good feedback to or lower price so more people can buy it, in mass. All Understandable. From my perspective, not advisable to people with low income.
