Description

ABSTRACT:
Tone amplitudes of signals which are generated in an electronic organ are converted into digital values and such values are cyclically memorized by a RAM storage at locations which are selected in accordance with a first function. The locations in the storage are then scanned in accordance with one or more second functions which differ from the first function in dependency on time, the thus ascertained or read-out digital values are thereupon converted into analog values, and the analog values are consolidated into processed tone signals. The second functions are or can be derived from the first function.
