As I didn´t get any reaction from developper side, I´ll post this again, this time in the english forum:
The state of the Solo Buttons in “MixConvert v6” is not being saved.
When Solo is active and the session is being saved and closed, the Solos will be deactivated after loading the project again.
We´re using MixConvert v6 to route specific sub-channels of a Multichannel track to a mono-bus or a sub-channel of an output bus. This is essential in Multichannel or 3D environment.
The standard MixConvert (not v6) is not usable as an alternative, as it sums all channels in the first step. A sub-channel solo doesn´t have an effect here (Bug Nr. 2 ?)
This behaviour is the same unter Nuendo 7.0 and 7.1.0
System: MacOs 10.11.6 (El Capitan), Nuendo 7.1.0 (Build 188)
Steinberg, please give a feedback wether you intend to solve this issue.
