A flyback system is described for use with a Mo¨ssbauer drive transducer of the coupled loudspeaker type operating at constant programmed velocity. A flyback control waveform is generated which quickly returns the transducer to its starting position and reestablishes the programmed velocity without exciting mechanical resonances. In addition, the range over which the velocity is maintained constant and counting is permitted is automatically held constant, independent of the programmed velocity, to eliminate systematic errors that would result from a correlation between average position and velocity.
