Abstract
An electronic musical instrument has a generator assigner for supplying note data and octave data by key stroke entry, a top octave synthesizer for generating 12 of the highest pitch signals for each note, a circuit for selecting one highest pitch signal from the 12 highest pitch signals according to note data, a binary counter for dividing one highest pitch signal to produce several pitch signals, and circuits for selecting one pitch signal out of several pitch signals obtained by the binary counter. The circuits are further controlled by both octave data and note data to generate octave series tone signals and non-octave series tone signals such as quint series tone signals.
Claims7
An electronic musical instrument comprising:
- a generator assigner which outputs assignment signals composed of note data representing the name of the particular note whose tone signal has been designated by a particular key stroke, and octave data representing the octave number of the selected tone;
- and at least one tone generator which has at least one pitch signal generating means and at least one octave controlling means, wherein said pitch signal generating means is controlled by said note data and generates the highest frequency pitch signal corresponding to the note name of the tone selected, and wherein at least one of said at least one tone generators produces plural signals by dividing said highest frequency pitch signal, and wherein said octave controlling means is controlled by said octave data and selects pitch signals from said plural signals, and said pitch signals have octave numbers corresponding to the tone selected, and said octave controlling means contains means for modifying the octave number of the pitch signals in accordance with said note data.
