The closest combo at the moment is rosegarden+ecasound. RG implements the JACK transport master mode while ecasound can operate as a transport slave. I don't know if anyone has tried this yet (I'm not a regular RG user myself, so I haven't had the time/energy to test this). As the whole transport thing is still very new, there will probably be quite a few problem before this works nicely out of the box. But anyways, we are getting closer. In case you are wondering, neither RG or Ardour implements the slave mode, so that's why you are stuck with ecasound for the moment. ;) Another interesting app, which recently got JACK transport support is Soundtracker. Far from perfect, but I've managed to get ecasound+soundtracker to work together. Basicly I had one soundtracker as the JACK master and two ecasounds as JACK slaves. I could press 'start' and 'stop' in soundtracker and both ecasound sessions would react to these events. Unfortunately soundtracker doesn't yet map the position information to song position, so you always had to start the recording from start. Still, I did manage to record a simple track with this setup and then mix it (.xm from st, one .wav from each ecasound). This is a big improvement as normally I'd need to render the .xm to .wav after each change. For those interested, I posted the following to linux-audio-dev (this thread eventually led to JACK) ~two years ago: http://www.eca.cx/lad/2001/May/0071.html So this was in May 2001. A lot has happened, but there's still a lot to do left. You can find more history info at http://www.eca.cx/laaga ... -- http://www.eca.cx Audio software for Linux!
