<p>Address memories (16) 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. In at least one these address memories (16), address data stored therein is read out in accordance with combination of the parameter determining factor corresponding to the address memory and data corresponding to at least another parameter determining factor. In other words, as an address memory corresponding to a certain parameter determining factor (designated as a second parameter determining factor), there are provided plural address memories corresponding to other parameter determining factors (designated as first parameter determining factors). 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 (19) and an address signal corresponding to combination of plural parameter determining factors thereby is formed. A set of parameters is read out from a parameter memory (17, 18) in response to this address signal. </p> |
