Abstract: 1317820 Electrophonic musical instruments THOMAS ORGAN CO 8 June 1970 27643/70 Heading G5J Apparatus for use in a keyboard electronic musical instrument comprises means for enabling sounding means for selected notes in each of a plurality of octave locations, and means for activating the enabled sounding means in octave locations selected in accordance with a control voltage, the apparatus, Fig. 1, is capable of several modes of operation. In a conventional organ mode, signals from the manual 11 and pedals are passed to keying control units 15, subsequently to the bass and treble keyers 25 and 26 and finally to the tone generators 27 and the output system 32. The output system consists of conventional tone filtering circuits, stop controls amplifiers and speakers. Lower manual 12 may key signals from tone generators 27 to output system 32 by a direct switch which is not shown. In the second mode, the keying drive unit 16b is energized to cause all notes being played on manuals 11 and 12 to sound in a predetermined relation to the note of highest pitch being played. This mechanism prevents wrong notes being played. Lockout means in control units is present notes in lower octave locations being sounded. In the third mode the automatic chord selector is energized. This provides enabling signal to the control units 15 for the notes of selected chords so they may be played in relation to the note of highest pitch played on manual 11. When the chord selector detects playing of a note incompatible with currently selected chord, a new chord is selected. The chord selector may have time constants such that a new chord is not selected so long as the melody notes are played legato. Signals from an automatic rhythm device 33 can control the sounding of the selected chord notes, e.g. root and fifth, in rhythmic patterns.

The invention is particularly useful for low angles of elevation, where ground reflexions detract from accuracy. In the embodiment there are n (n > 2) aerial elements above a common element c, Fig. 1 (not shown), the phase difference between element c and element n being # n . In general # n  = 2#(I n +F n ) where F n  is a fraction and In is an integer. The phase discriminator can measure only 2#F n  and the Specification includes a detailed analysis for finding I n . The difference in phase ## between the outputs of aerials n and n + 1 is given by: ## = (A/#F/ + B + C#F). 2#, provided /##/<#, where #F is the measured (fractional) phase difference, where A, B and C are zero or unity, as tabulated in the Specification, in dependence on whether |#F| is less than, equal to or greater than ¢ and the sign of #F. Digital phase measurement as described in Specifications 1,333,546 or 1,295,010 may be utilized and the logic processing corresponding to the above equation may be effected as shown in Fig. 5. The Specification considers the case where further ambiguities arise, Fig. 9 (not shown). For angles of elevation up to some 24 degrees a combination with overlapping-beam digitalamplitude comparison is utilized, Figs. 10, 11, 12 (none shown).
