I'm new to Pd but gone through a few tutorials and done some simple patches. My main DAW is Ableton Live and I'd really like to use Pd with Live when performing in the future.

I've tried to do this myself in a few ways. And I've asked in the Pd IRC for help. And spent a bit of time on Google. But no results.

So I wonder if there's a way to control / sync Live and Pd tempo via MIDI routing? Well any other method would be nice!

Thanks for the help

Hm, I suppose no-one know how to do it :/ I'll get down and try some more.

I was looking up info on this briefly recently. A good place to start is looking at midi clock signals and midi clock sync. That's the hardware solution for some syncing that already exists in the midi standard.

From what I remember, there are numerous ways to implement this, and its handled differently in different hosts.

not sure how helpful this is.

I have never heard of an external or patch that could receive or send midi sync signal.
Maybe you can try to set Live's tempo via midi notes or cc message. Connect pd's midi out to ableton via IAC (osx) or midi yoke (win) and map a cc controller to the tempo or a note to the tap tempo in Live. For Live -> pd communication you could simply use a dummy clip as a metronome.
I don't know if any of this will work as I didn't try it. These are just some ideas..
It would be nice to have a way to sync pd with any DAW. I think it would require a external that understands MTC and MMC messages, but I have not enough programming skills / time to learn to write one..

hope it helps.

I've tried (with IAC) to sync the tempo. But when I try to sync it it always gets weird. I might have some parameters wrong.

I'm looking for a solution to this as well. I would like to be able to increase/decrease Abletons bpm/tempo from PD CC messages. Any luck?

I know you can do this its simple

I think you should read the Ableton Live manual thoroughly and find out which midi messages it can respond to and then try to control it from outside. If you have a purchased (legal) instance of Live you should write to their support email asking for that. After all, you've paid for it.
A friend of mine bought a very nice 16-channels midi controlled mixing board (motorised faders and such) and had to swim its whole manual to find out that it uses port 110 to send midi machine code (MMC) to control the DAW playbar. The problem was not on the DAW but on his own lack of info.
Best regards.
