live.observer stops observing when transport is off ?

[chapelier fou]

Hi.
I'm monitoring the time signature and output a midi note to light led when it's a 3 beats or 4 beats time signature.
For some reason i got a note off sent when i stop transport. Can anyone explain this ?
This only way i've find so far is to send a continuous flow of bang with a metro to keep it going.
thanks !

I think that Live generally sends note off at stop if needed to avoid hanging notes.

But remember that you can also use [plugsync~] to monitor the time signature.
It continually reports info from the host at intervals of 64 samples (~1.5ms @44.1kHz).

Gosh, you're right ! My bad...
And thanks for the plugsync~tip, i didn't know that !

[chapelier fou]

I just encounter another problem with this. Observers seem to be stopped when transport is off. For instance, with my clip linker device, i won't work if the transport is not running. How do you guys deal with it ?

I don't think that observers in general are depending on transport state.
Can you describe a reproducible situation where it doesn't work as expected?

[chapelier fou]

for instance, in the patch above, the live.observer observing property fired_slot_index doesn't report anything if transport is off and i launch a clip.

[broc]

I've checked with 'print' that in this case the observer reports -1 which seems correct as the clip starts immediately. Note that the property fired_slot_index refers to the blinking state (see LOM). Maybe you need to observe the property playing_slot_index instead or additionally.

[chapelier fou]

It makes sense. So i can't imagine it working with quantized launches of clips...
Thank you.

[greaterthanzero]

Don't quantized launches require the transport be moving anyway?

[chapelier fou]

i mean : with a 1 bar global quantization and transport stopped, launching 2 clips at the 'same' time would result to a 1 bar offset between the 2.
