note that the destructive/tape mode added to enable Harrison's XDubber
product was designed to replace the Tascam MMR8. This is a different
device than the MX2424, but its a point worth making, i think.

yes, ardour can replace the mx2424 fairly easily.

ardour does not do varispeed recording, but assuming your MTC source is
audio-clocked synced to your audio interface (typical in a pro-studio
setup), this issue doesn't arise. in fact, ardour's default assumption
is that an MTC source is audio-clock synced (this can be modified to
accomodate varispeed syncing to an MTC source).

yes, it writes BWF files and the "original" time is in the file, for
some definition of "original". it works for others. if it doesn't work
for you, that can be fixed.

RME HDSP MADI is fully supported under linux. Improvements are coming,
but not necessary for almost anything you might want to do with it.

not natively. Harrison have their own implementation of this, so it can
be done, but theirs is not available as a GPL'ed product. it does
understand MMC natively.

convert to MTC. at which point, ardour will sync more accurately and
quicker than just about anything on the market (according to people who
should know about this stuff).
