[LAD] Jack MTC/MMC slaving

Hello, I'm guessing from the research I've done online and from the lack of responses to my LAU message ( http://www.nabble.com/Slaving-jack-to-MMC-MTC-to20357929.html ) that JACK does not currently support slaving to external (or internal?) devices via MMC/MTC. I'm a C/C++ developer by trade, so I'm happy to get my hands dirty, but I wanted to know what other work, if any, has been done on this front. I've been told that both Rosegarden and Ardour can sync to MTC, but that they cannot then drive JACK transport in that mode. Would it be difficult to move this code over to JACK? Is there a reason this in't desirable? There's a small program called jackctlmmc that seems to do want I want, but it's a bit limited (seems pretty hardcoded) and I think that such a desirable feature should be integrated into a more widely used program. Any thoughts? Thanks, -- Alex
