ABSTRACT:
Address memories storing address data, individually, for respective parameter determining factors (e.g., tone color kind, tone pitch, key touch or other factors) are provided for the respective parameter determining factors. Address data stored in at least one of these address memories is read out in accordance with a combination of the parameter determining factor corresponding to the address memory and data corresponding to at least another parameter determining factor. In other words, plural address memories corresponding to parameter determining factors (designated as first parameter determining factors) are provided with an address memory corresponding to another parameter determining factor (designated as a second parameter determining factor). One address memory is designated by data corresponding to a first parameter determining factor and address data is read out from this address memory in correspondence to the second parameter determining factor. Address data read out from respective address memories are operated by an operation circuit and an address signal corresponding to a combination of plural parameter determining factors is thereby formed. A set of parameters is read out from a parameter memory in response to this address signal.
