[primis]

There's an entirely web-native replacement for upload/downloading tracks now https://stefano.brilli.me/webminidisc/ It's based off the reverse engineer minidisc python libraries and, imho, is super impressive. The author even figured out how to dump atrac data off any netMD capable deck (not just the MZ-RH1).

Minor note: ATRAC extraction on non-RH1 models and Hi-MD support is only available on the fork at web.minidisc.wiki (Web MiniDisc Pro).
