  When the Eu­ro­pean Muon beam­lines at the ISIS pulsed neu­tron and muon source [1] up­graded their front end mag­nets, it was de­sired that these new mag­nets should be con­trol­lable re­motely. This work was un­der­taken by the team re­spon­si­ble for in­stru­ment con­trol, who are in the process of a phased up­grade of in­stru­ment con­trol soft­ware from a lo­cally de­vel­oped sys­tem (SECI) to an EPICS [2] based one (IBEX [3,4]). To in­crease the com­plex­ity of the task, parts of the front end needed to be con­trolled only by an in­di­vid­ual in­stru­ment beam­line, whilst some val­ues needed to be tuned to the best com­pro­mise avail­able for all three beam­lines. Fur­ther­more, the muon in­stru­ments were not ready for an up­grade to a full IBEX sys­tem at that time. By com­bin­ing SECI, IBEX and the Man­tid [5] data re­duc­tion pack­age the re­quired con­trol and tun­ing has been achieved. This paper will give de­tails of the chal­lenges, the topol­ogy of the so­lu­tion, how the cur­rent mixed sys­tem is per­form­ing, and what will be changed when the muon in­stru­ments are con­verted to IBEX.
