Well, mostly, I'll need to analyze audio and CV signals, indeed, so bandwidth and levels will be rather low, but too high for audio devices (+/- 15v max). Thing is, these signals coming out of home made devices, and me not being too much of an expert into building them, I wouldn't want to take the risk of screwing my audio hardware's input
Thanks for your reply.
In the meantime, I've a rather laconic reply from the makers of my scope, saying that no, "there are no plans at this moment to write software for the MAC OS.", which isn't very encourageing either :/
