Help please; am baffled ! 18A Controller to choose musical form with old key (7,5) I have ?P???A?M?U?E. Not sure if 19D (Opposite to rhyming) is adverse or reverse, but even trying A or R doesn't help. Thanks

optical mouse (controller) - 'opt' (choose) + anagram of 'musical' + 'o' (old) + 'e' (key)

OPTICAL MOUSE [=controller, of computer]

choose = OPT
musical form with old = anagram of musical+o = ICALMOUS [in this case]
key = E

[dannyk13]

OPtical mouse - choose = Opt followed by anagram of musical with old = o and key = e
