PCT No. PCT/EP88/00702 Sec. 371 Date Jan. 14, 1993 Sec. 102(e) Date Jan. 14, 1993 PCT Filed Aug. 3, 1988 PCT Pub. No. WO89/01219 PCT Pub. Date Feb. 9, 1989.A pitch control system for the automatic pitch correction according to a harmony-dependent tuning, especially the harmonic tuning, for a musical instrument, having an input device for the input of note input signals in a pre-determined fixed tuning, especially the tempered tuning, and having a note generation device to which the note input signals are applicable, comprises a chord recognition circuit which ascertains at each input signal pattern corresponding to a chord whether this input signal pattern corresponds to a chord pattern from a pre-determined quantity of chord patterns, a signal pattern store circuit in which for each chord pattern of the pre-determined quantity of chord patterns a signal pattern is stored, and a control circuit which, when the chord recognition circuit ascertains that an input signal pattern is present corresponding to one of the pre-determined chord patterns, causes the signal pattern store circuit to emit the signal pattern, corresponding to the ascertained chord pattern, to the note generation device, for the production of the chord in each case in the variable tuning. |
