Good morning.
I don’t know why, but when I add a new song to VST Live Pro and want to set up a piano plugin, for example, my midi channel changes from 1 to 13. What’s the matter? I will be grateful for your response.
If you talk about Layers:
set up your Layer as you like, then menu Layers/Save Default Layer. From now on, each new Song, Part, or Layer will appear with those settings. You probably accidently saved a default Layer with Midi ch 13?
