-> Sometimes the controller enter in a power off/on loop since last firmware, and I have to close the DAW to stop it.
-> Faders starting positions are inaccurate, like 3 db under the daw, and it cause problems when touching them, moving DAW faders down to that 3 dbs.
-> Tried to change Fader Speed to launch calibrate mode, but the controller switching off and on before calibrating process.
The controller is almost unusable at this point ....
EDIT :
I talked to technical support, who led me to resolve 99 % of the problems :
My Ableton Push and my Presonus Faderport power supplies was inverted ! Too many power supplies under that desk, in a closed box with an APC anti-surge ...
So, with the good power supply, I could change fader speed and the controller entered in calibrating mode without any problem. The way faders are working is a lot better.
It still not 100% precise, with a -0.3 db at the very first touch of a fader, with any touch sensitivity.
