Latency between Ableton and Resolume

[dcotecol]

Hi !

I'm working on a new show in which I want to controll video (with Resolume) and audio (with Ableton Live). I download LoopMidi in order to send midi note from Live to resolume with a midi clip. Its work very well. The problem is when I try to controll an effect with a fader or a potentiometer. Ableton send the Midi informations to Resolume, but there is a big latency, and the motion is really not smooth.

So, it's looks like there is a problem about sending multiple data in the same time (with a fader for exemple).

Does everyone have an idea about how to fix that ? I really need to controll my audio effect and my video effect in the same time

I've tried other virtual MIDI, as LoopBeOne, and I have the same issue.

Thanks !

Have you tried using OSC from Ableton to Resolume?
This too might be another way of conversion without the need for driver installs:

Thanks for your reply !
No I didn't try OSC yet because I read that to link Ableton and Resolume on the same computer, MIDI is the best. I think OSC is needed when you have multiple computer. But I will try it, maybe I will have less issue with OSC :/

I think I have the same issue with OSC, with Chataigne...
I also tried LoopMidi on an other PC (my laptop) : I have the same issue

Dumb question but are there any delays setup in ableton, and are there any buffers that can be modified? I haven't used ableton in a hot min.

[dcotecol]

Yes there is a buffers that I can modified. But it's for sound, not for MIDI, so it don't change anything. Anyway, when I launch a simple MIDI clip with a note with Ableton, there is no latence to send it to Resolume. Once again, it's only with the faders and potentiometers

Hmmmmm, I can see the latency is between Live and loopMidi (there is realtime data, so I can see there is a latency). So the problem is there... and I need to send Midi before send OSC

What are the machine specs, and what kind of footage are you playing?

[dcotecol]

I'm juste playing basic test footage from resolume (line scape), in order to test the configuration.
I have a PC with Ryzen 2700 + GTX 1080 + 16GO DRR4 + SSD for system and applications.
So, I don't think it's a performance issue .

Yeah, my money was on the conversion from Live to the midi driver adapter you are using, which is why I suggested OSC as I thought it might use a different driver (at least for troubleshooting purposes). What I find troubling is that it's not a global latency but only on faders, that has me a bit puzzled.

I have Live 10 on my machine, let me see if I can re-create.
