摘要： A sustainer for providing sustained sounds from a musical instrument has a feedback circuit for converting a pickup signal representing a vibration of a string or other vibratory element to a drive signal and applying drive forces to the vibratory element responsive to the drive signal. The sustainer is arranged to compensate for the phase lag of the pickup signal relative to motion of the vibratory element and to compensate for the phase lag of the drive forces provided by the driver relative to the drive signal. The feedback circuit may be arranged to provide a phase difference between the drive signal and the pickup signal such that the phase difference varies with frequency towards a drive signal leading phase difference with increasing frequency. This phase compensation provides enhanced response of the strings in the fundamental mode of vibration. The driver preferably is arranged so that the drive forces applied to the strings do not vary with lateral movement of the strings.
