I heard you.

Up to this point I've been using timemachine for all audio captures - I can't 
use Ardour for recording soft sound sources due to CPU/Memory restrictions. 
Timemachine works fine for this, you just set the lead-in time to a 
relatively small amount. I like the 'One Big Button' design of the GUI :)

My main reason for using timemachine is because it's on the menu and it works, 
I confess. The one limitation is that mostly I want the captures to be easily 
time-synched i.e start at 00:00:0000 and end at nn:nn:nnnn as audio dumps 
from Ardour and Hydrogen do by default. I've kind of assume that timemachine 
wasn't really built for this, so haven't bothered to look too hard.

Would this be easy to set up using jack_capture?

I want a big red button which does precisely this, I can make my own gui if 
need be, but Ideally I'd like to see a record button on qjackctl.
