Abstract

Abstract A programmer for a music synthesizer including a keyboard and M independent voice modules (channels) and wherein the characteristics of each module are dependent upon K independent parameters, each parameter defined by an analog voltage level. The programmer is capable of storing N distinct programs, each program including information defining K parameters for each of M modules. The programmer is comprised of a common set of K potentiometers which are coupled through an analog to digital (A/D) converter means. The output of the A/D converter means is applied selectively either to a digital memory for storage at a location defined by operator controlled switches or through a digital to analog (D/A) converter means to the voice modules. Alternatively, information applied to the D/A converter means for application to the voice modules can be derived from the digital memory.
