As I had no reply to my first post last week... I ask again!

I need to use Ableton Live inside max (rewire~) and I want to sync it to an external MIDI clock. Here is my problem : With rewire~, I can send Start/stop/tempo/position messages to Live, but I can't see how to sync it to a Midi clock. I tried to send the midi clock with the "midi" message to rewire~, but it doesn't seems to work (or I don't know how to format this message correctly...).

Any help is welcome...

I already ask this 2 times... and no replies. Does it mean that it's a really stupid question, or does really nobody can answer ?

Ok, I try a third (& last) time :

Hey Mathieu,

here are some ideas: I'd use rtin -> sync~ and see if the (float) bpm info from sync~'s middle outlet is accurate enough for syncing (strip the bpm and send to rewire~ with 'tempo $1'). You should get the start/stop messages with 'sel 250 252' directly from rtin. If this doesn't work you could try detecting the beginning of a bar from the signal outlet of sync~ with >~ and edge~ (or by counting midi ticks), and send a position message to rewire~. You would need to calculate how many samples are in a bar at the current bpm and count how many bars have already played. Haven't tried any of this ... Good luck, g.

Thanks for your reply, Georg. I already tried the sync~ -> bpm -> tempo -> rewire~ solution, but it's not accurate enough. (I want to be able to follow fast tempo changes and start / stop messages... sync~ doesn't react very well and sometime takes a couple of beats to output the right tempo after a change). In fact, I need to know if it's possible or not to send a midi message to rewire~ containing a midi clock. If it's not possible that way, I will have to deal with tempo / position messages... I just hoped that could be easier. Midi clock is a simple and robust sync ; It would be too bad to not be able to use it directly with rewire~.

Thanks

Mathieu

Dear Mathieu, please explain me if you have some particular reason to use Live inside Max ,..i work with my max patches "inside" Live, receiving reliable and solid timing from it using hostsync~ and ad_rewire driver..and then sync Live to any external device via midi..

Because with max "inside Live" (ad_rewire driver) adc~ is disabled. With rewire, as far as I know, audio can only go in one way : from client to host. So in your configuration, you can't process an external audio source in max, and you can't send audio from live to max.

Am I wrong ?

MathieU

you are right :(

Hi Mathieu,

I only just saw your post

You can sync Live using a pitch bend message from Max/MSP If this is useful write back to me at andrew.robertson@elec.qmul.ac.uk

Also, I have a question for you. Can you sync Live by sending a Midi Clock message from Max.

I've always used my pitchbend method with Ableton's Midi map, but for various reasons want to check out other ways too.

If you're interested, check out youtube.com/bkeepersystem

for some of the work

Regards, Andrew

I am very interested in this as well. If it is not proprietary knowledge, could you please share with us as well? I am sure others in the future may want to know this.

Hi,

I discovered a nice way to do this thanks to Mitch Turner who posted on this forum. He posted the following patch which you send on midiout "from Max/MSP 1 (or 2)"

In Live you must make sure you are set to recieve Midi Clock - i.e. from Max/MSP 1 is set sync ON in Midi preferences. Then activate external switch by switching EXT on in Live's main control bar.

So here's the patch in Max:

And if people are interested in how to sync live using Midi pitchbend, let me know or search previous messages here.

Cheers, Andrew

i am so glad that i found this patch! thankyou so much. its ancient - but still works well. i couldnt figure out why my midiout was not working - now i understand that the midi clock message is 258! mine was sending out 'midi'!

thanks!
