how to update ableton's tempo

October 23, 2013 | 7:05 am

i am a little confused how to update the tempo of ableton from max. i am getting this tempo from a number box in a max patch (max is playing middleman between another application here).

i looked up hostsync~ help and couldnt figure out how to get it to send anything over to ableton. I tried the adl_rewire as my audio driver and the DAC kept flipping off.

now i am wondering, should i be using the rewire~ object instead? and does it matter what driver my system is set to?

Is there a reason you’re avoiding M4L? it’d be really simple to do it using the API.

and what about midi ?

Evan: i’m using this program called Espgrid, so i’m not sure how to integrate that into m4l. you can find it here inside the helpful code subfolder.

Chapelier: how do i go about this with midi? that would be ideal!

Make an empty scene (remove all stop buttons) in Live and set the BPM and time signature.
Do a midi learn with the play function of the scene. Send that note from max to ableton. Voila !
A very simple but old school solution.

hi andro: not sure if that will work because i’m not going to be updating the tempo using note values or sliders. it’s through a number box. i will try it though!

what is espgrid outputting? OSC, I suspect?

And yeah, an m4l client would be ideal.

I don’t get it i guess. I would stick a ctlout to your number box, scale it and midi learn your tempo in live. Am i totally missing the point ?

ctlout and midi learn works only for a limited range of 128 BPM values.

and it’s kind of hacky, in that you need to redo mapping for every new live set where you attempt to use espgrid.
