I've tried to do a search but haven't found anything on this subject. So if I'm opening up something already discussed, please give me the reference and I apologize in advance.
I'd like to use my oscilloscope to display signals coming out of analog synthesizer modules or other audio devices. The plugs could be banana, TRS, RCA, XLR, etc. I suppose I could just make plugs with exposed wires and use clips, but I'm worried that might wreak too much havoc on the probe's signal. I've been searching the net for probe tips using these plugs and the only ones I'm running across are for meters, not scopes.
So, can anybody lend some advice or assistance here? Am I thinking like a newbie, should know better and just do it?

Ideally, XLR are balanced, so you could, if you want to maintain balance, make a lead with two BNCs, one for each leg, with the outer part of the coax connector returned to the cable shield, & use two channels in the "poor man's differential" setup.
Often, people don't bother, though.
RCA to BNC adaptors are common, not so much TRS or banana plugs.
There are plenty of cheapo BNC to alligator clip leads around---you could just ditch the alligators & replace them with banana plugs or whatever.
If you are looking at something which expects a 600
termination this complicates things, as they aren't a standard BNC terminator, so you would probably have to make one if you are fussy about setting the "correct voltage".
A lot of more modern designs have very low output impedance, so will present "near as dammit" the same voltage to a 600
as to much higher loads.
