Hi, it’s about two or three weeks than while I’m playing In ableton with sp plugin, suddenly It lost the sp mixer output.
I mean the inputs are still comin in, like you can see in the picture attached, but aren’t flowing out from the sp mixer outs channels.
If I close and reopen ableton it works again but, after let’s say 20 min it losts again the outputs.

Someone has experienced the same issue?

When happens, if I press stop and then play it works again.
