RE: How is Z3ta and Automap working out?
I understand Automap uses the plugin automation to control the parameters. Therefore if you can access the automation in your DAW then Z3ta should give that parameter to Automap 3.1 to allocate to your Remote SL.
I have just tried loading the Automap version of Zeta+ from Sonar 8 and I can acces the EG parameters directly. Presumably this is independent of the internal velocity mappings.
However, there is no built in automap template for Z3ta+ so the prameters are mapped in the order they appear accross 13 pages without regard to the layout of the controls. Either you would need to edit the template yourself or hope someone posts a template on the Novation community website.
I've tried doing this for Dimension Pro and have uploaded it on the website but it was a major pain to edit with so many parameters. I wouldn't fancy doing this on Z3ta + without a very large monitor!
