Abstract

The instrument contains a memory (14) which contains samples of wave shapes in several individually addressable memory areas. An interpolator (15) can determine intermediate values between adjacent basic sound data in real time during the reading out or during the storing. The individual sound data are read out as a function of sound parameters. The order of the individual sound data to be read out is determined as a function of these sound parameters (Figure 1). <IMAGE>
