Abstract
An arpeggio notes generating apparatus includes a ROM which stores data defining a plurality of arpeggio patterns and a plurality of groove patterns. An arpeggio pattern is composed of a succession of chord constituent notes to be generated at respectively corresponding timings. A set of data for each note include data to identify the note generation timing, the key number, the duration and the velocity value. A groove pattern is composed of a succession of note generation modifier data sets, and each set is for each arpeggio note and includes data to define amounts of modification to be applied to the data for each note generation. Two arpeggio patterns and two groove patterns are selected in correspondence. The note generation timing, the durations and the velocity values in each arpeggio pattern are individually modified according to the corresponding data in each groove pattern to provide two modified arpeggio patterns. The note numbers of the keys depressed in the arpeggio key range are allotted to the key numbers. The modified arpeggio patterns are read out by interruption processing, and determine each note generation to impart groovy sensation in the musical performance.
