摘要： A keyboard operated musical instrument is disclosed in which the number of tone generators can be less than the number of keyswitches in a keyboard array of keyswitches. A binary-tree search is programmed to search subsets of the keyswitches to find keyswitches that have been actuated. The subsets are selected in an adaptive fashion which minimizes the search time required to detect and identify all the actuated keyswitches. A modular assignment subsystem is described whereby tone generators are assigned to actuated keyswitches according to a predetermined priority logic.

摘要： A keyboard operated electronic musical instrument is disclosed which has a number of tone generators which are assigned to actuated keyswitches. Musical tones having an anharmonic overtones structure are produced by generating a number of component waveshapes each having a different fundamental frequency. These component waveshapes are summed to produce a single tone. Each component waveshape has a spectral content of a preselected subset of non-zero harmonic coefficients. The various components have mutually exclusive selection for the non-zero harmonic coefficients.

摘要： A keyboard operated electronic musical instrument is disclosed in which an independent monophonic tone synthesizer is operated from the same keyboard that controls the generation of tone from a polyphonic tone generation system. The highest frequency note is assigned to the monophonic tone synthesizer and all other actuated keyboard switches are assigned to the polyphonic tone generation system. The detection of the highest note is initiated each time that a keyswitch changes from an unactuated to an actuated state. An alternative arrangement is to assign the lowest frequency note to the monophonic tone synthesizer.

摘要： In an electrical tone generator apparatus is provided for automatically selecting one of a library of chord types which is closest to a chord fingered on a fretted string instrument. The closest decision is made by processing the fingered fret input data by a set of matched filters each of which corresponds to a member of the library of chord types. The chord type decision is made to correspond to the matched filter producing the maximum output response. The selection between chord types yielding equal responses is resolved by priority logic based upon the frequency of chord usage. A root note is chosen for each chord type. Note keying data is generated from the selected chord types which is transposed to the correct musical pitches in response to the chosen root note. The note keying data is grated by an automatic rhythm generator and the output is used to actuate electronic musical tone generators.

摘要： A complementer for floating point binary numbers utilizes two digital logic decision rules selected by the value of the power of the input number. The first decision rule is selected for an input power of -1 and constructs a power and mantissa determined by the binary sequence form of the input mantissa. The second decision rule is selected for input powers less than -1 and constructs a mantissa determined by the binary sequence form of the input mantissa and the value of the power. The complemented power is set to a -1 value. The complementer is advantageously employed in digital electronic musical instruments.

摘要： A keyboard operated electronic musical instrument with polyphonic portamento and glissando effects in which each key controls one of a number of tone generators through a table of frequency numbers. The frequency transitions are achieved by subtracting the frequency number of a new note from the frequency number controlling the current frequency of an assigned tone generator. A predetermined fraction of the difference is stored in increment registers and added successively to the frequency numbers of the current notes until these numbers are equal to the frequency number of the new note. The addition rate, which determines the frequency transition time, is adjustable by means of a variable frequency time clock. The assignment of the tone generators to the actuated keyswitches is accomplished in a manner which prevents objectionable frequency cross-over transitions even when the number of notes in successive chords is changed.

摘要： A keyboard operated electronic musical instrument in which a number of tone generators are assigned to actuated keyswitches. When a keyswitch is actuated, a tone generator is assigned with a musical waveshape selected from a library of waveshapes which are ordered in a predetermined arrangement. The assignment of waveshapes is made in a priority order according to the musical frequencies associated with the actuated keyswitches so that a chorus effect is obtained in which each note of a group of simultaneous notes has its own tone color. The assignment of waveshapes is made in an adaptive manner so that the melody line retains its own distinctive sound even when the number of notes played simultaneously on a keyboard changes. Vibrato effects can selectively be applied to any of the set of waveshapes.

摘要： An electronic digital type organ having one or more keyboards generating two or more harmonically related tones in response to keying a melody monophonically on one of the keyboards. The harmonic tones may be of different tonal quality, so as to produce the effect of different instruments. The harmonic tones are generated automatically at a pitch determined by either the next lowest note to the accompaniment notes played on another keyboard or, if no other key is depressed, a pitch that is determined by the melody note and stored half-tone interval information.

摘要： An automatic arpeggio for a keyboard-operated instrument in which a tone generator is assigned to a key when the key is actuated, the fundamental frequency of the assigned tone generator being determined by octave and note data stored as a control word in a memory in response to operation of the key. On keying the different notes of the arpeggio chord on the keyboard and activating an arpeggio Load switch, a control word is loaded in the memory for each key of the arpeggio chord, the words being coded to identify the value of the note and the sequence number of the note in the arpeggio chord. The arpeggio chord control words in memory are transferred one at a time to a tone generator in a sequence according to the stored sequence numbers of the control words. Arithmetic means, in synchronism with an arpeggio clock, generates note sequence numbers by which the control words are addressed in memory. The note value is transferred to the tone generator together with octave information from the arithmetic means. The tone generator, in response to the octave and note information received with each control word, generates the corresponding tone. The arithmetic unit changes the note sequence number for addressing a different control word of the arpeggio chord with each arpeggio clock. The arithmetic unit is capable of modifying the note number and the octave number in various types of sequences under the selective control of the musician.

摘要： A single amplitude curve generator is time shared amongst a plurality of musical tone generators for controlling their musical shapes. The curve generator creates a wide variety of envelope characteristics by implementing a recursive computation algorithm for selected choices of a single curve shape parameter coupled with the use of a collection of timing clocks used to vary the time intervals associated with the attack, decay, and release regions of the musical tone envelope. Provision is made for forcing the release of a tone generator when a limited number of tone generators have been completely assigned in a keyboard musical instrument and a new note key switch is actuated. Note release signals can be ignored until the amplitude curve generator has completed the attack and decay regions for a given tone generator.
