I guess the question is what are you doing with the 8 tracks. The
default 8 track channel has only two outputs. So it would mean only 32
extra ports (compared to jack_capture).

Many might want to use 8 channel tracks with 8 separate outputs for each
track. This would mean a lot more outputs.

You can use jack_lsp to check the amount.

See the third line of the usage:

v2 at mustis:~/dev/audio/jack_capture-0.9.16$ ./jack_capture --help
Usage: jack_capture  [--bitdepth n] [--bufsize seconds] [--channels n]
[--port port] [filename]
                     [ -b n]        [ -B seconds]       [ -c n]
[ -p port]

If it doesn't stand for seconds, what does it mean? --bufsize?
