[S37E] S37 Editor sometimes not responding in Ableton Live

Hi there,
I encountered a strange problem. Im using Editor 1.0.0 (VST-Version) with Firmware 1.2.0 under Ableotn Live 9.6.2 on OS X (latest El capitan build). Sub 37 is connected via usb. I have mapped the controls of the editor to ableton macros. When I switch a patch or change the active trak, changes from the mapped controls dont change the sound. The knobs are turning and moving in the editor, but the sound of the sub 37 doesnt change. I have to click with the mouse in the editor window, move the knob a bit, and then it reacts again and changes the sound to the controlls.

Any help?

Cheers

Please send me the Ableton project with clear steps for reproduction, and I’ll check it locally.

Thanks for the info.
