[ardour-dev] MTC & MMC issues Beta 19...

this is what I've been doing to solve said problem:

run ecasound in interactive mode as jack master, sending mmc out the midi
run ardour in jack sync mode
ready sequencer to start on MMC

then when I type
in ecasound, both the external sequencer and ardour start

this has been working, but see my ranting and raving about float and xruns

I really recommend tracking each sequencer track to ardour before mixdown -
or at least a stereo mix

that way when you're actually MIXING the final mix, ardour won't have to be
sync'd with the sequencer.  all that'll already be done and there and in
sync (watch out for ardour placing audio late and you having to slide it
back in place - this is another issue that may be fixed in your version) and
you can mix mix mix

At Jessie's request I am posting this to Ardour-dev as well after posting it
to Ardour-users.

This was the initial post that Dave Phillips responded to...

I am trying to do this;

I need to run a sequencing app (In this case Sonar XL on an external box) to
sync midi accurately to Ardour so I can lay my new recorded audio trax into
Ardour. THen, when I have the takes I'm happy with, I'll mix down the synced
midi to stero at the same time I mix down (and Master with Jamin) the
guitars, etc.

I can run Rosegarden and Ardour when they are both slaved to Jack
transport...but Rosegarden is a pain... and is it accurate as in song
accurate? And I'm not sure I can have the sounds I want in RG
anyway...Specifically I wan't the Edirol Hypercanvas softsynth 'cause the
format and sounds are just killer!!! So that's kinda why I need to run it in
Sonar. I have jack_vst working but Hypercanvas dies out after about 10 mins.

So far in my experimenting, when I set Ardour up to send MTC and Sonar to
listen for it, Ardour puts up an error message like {paraphrasing} can't
quarter note message or something?? It's transmitting something but nothing
Sonar will recognize.  I don't think I tried to slave ardour because that
would defeat my purpose in keeping it synced later for mixdown / mastering.

Does Jack transport have the ability to send MMC or MTC?

I need to get this demo ~done~. I have tried dumping the midi stuff into a
pre mixed stereo image in Ardour but it just doesn't work; I have no control
over those instruments at mix down. It's hard enough to mix vocals in with
midi generated backing as it is...If ther is some other work around, I'd luv
to know. I am trying to avoid doing this simple demo in Windows at all. I
look at the Sonar thing as another form of "hardware sequencer" if you will.
