We thought we would use the most commonly used method "Sampling" as a basis. Unfortunately, human voice does not scale gracefully as in other instrumental sounds. We realized that it is nearly impossible to cover the entire instrument range with Sampling Technologies itself. We are currently studying how to overcome the problem. For the time being, we demonstrated our prototype "12 Note Mapper with the 12 Note Solfege" at Cool Product Expo 2009. The purpose of this demonstration was to find out the interest level. We might introduce this intrim solution if we can meet a certain need.
