  The pulse-to-pulse modulation of the SIS-ESR control system is described. Fast response to operator interaction and to changes in process conditions is emphasized as well as the essential part played by the timing system in pulse-to-pulse modulation. The benefits of pulse-to-pulse modulation in acceleration operating have been described as early as ’77 for the CERN’s PS complex. It is an effective way to increase the overall output of valuable beamtime of one or more accelerators. With beamsharing, rarely all users of the beam will be unable to accept the beam at the same time. If the PPM-handling quickly responds to changing conditions, there will be virtually no dead-time in the machine operating due to inevitable dead-times of experiments, e.g. during new experimental setups. In a multi-accelerator facility, PPM is almost imperative. Asynchronously running machines, every one of them operating as an injector for the next one, normally have time left between subsequent injections that can be used for experiments.
