Abstract
One of the many practical applications of the MIDIM‐system in the last few years has been the duplication of existing sound families, in particular those of musical and speech sounds. In the first part of this article we will define the concept of a sound duplication and show a method by which means duplications may be found. This method is particularly suitable for the MIDIM/VOSIM‐system. In the second part an application of this method is shown for the instrumental concept Gender drawn from the Central‐Javanese Karawitan. We shall also concern ourselves with a number of other concepts from this music culture.
