Why can't master tempo be controlled by Max For Live device?

[digid]

I have mapped "Master tempo" as the destination for the new LFO device in Live 9 (Max For Live device), but it's not working at all. Live seems to slow down to a halt, and even though the master tempo is sort of(!) changing according to the LFO, the master tempo is not reacting as I thought it would.

Why doesn't this work? Have also tried with another LFO Max For Live device, but with the same result.

Is "Master tempo" not made for this kind of live modulation?

[digid]

Changing manually works just fine - tempo is slowing up and down as I slide the tempo up and down with the mouse.

I would therefore expect the same kind of behaviour if I modulate the master tempo with a sine curve through the LFO Max For Live object, but this is not so.

So, no - this is not the behaviour one should expect.

is your lfo synced to tempo ?

[synnack]

does it behave the same for you if the LFO is synced to tempo versus not?

What is the Amount of LFO? At 100..... That'd be insane haha

Edit: but I may have to tinker with this idea to attempt Risset beats

If i open a blank live set, add a MIDI LFO device from the library to an empty MIDI track. Map it to global tempo, it works exactly as expected. Tempo following the sine wave. Seems to work here.

Ah I see what you guys are saying now. You're right. No errors in the Max window either.

Nope, it is running on its own clock ("Freq" is active, not sync), so that shouldn't be an issue.

This has now been confirmed as a bug by Ableton, so hopefully they'll get a fix out soon(ish).

Was this ever fixed? Still not working with the LFO in Live 9.7

Have you tried to map the song tempo to an external MIDI parameter? Or an alternative LFO? There's also a discussion elsewhere in the forums about tempo and sync that migt be enlightening.
