Hi,
The problem comes from Analog Lab 3 (and not from the Piano V2).
We have reproduced the issue here, and are currently fixing it, we will release a hotfix soon fixing the problem.
However, installing the Piano V2 standalone only is ok, the workaround should work on your side.
Does the sustain pedal works into Piano V2 in standalone ?
Could you check on Analog Lab 3 using the same Piano preset than the Sustain Pedal is still not working ?
Thanks,
PL
