After setting up the JV1010 as an External Instrument in VST Connections, I went to Add track–>Instrument, and set my virtual instrument as the JV1010 (external plug-in). So then the JV1010 is my output for the instrument track. I can then select all the patches from the drop down on the instrument track, but it doesn’t play any of them. I’m pretty sure they are only showing up because Cubase has the script file for them, not because Cubase is getting them from the JV1010. And again, when I try to edit the sounds of the JV1010, I get a small window that doesn’t allow me to select patches. It only lets me change delay and return gain. When I click edit instrument, this should open to an edit window like any VST plug-in with a list of all the patches and tons of tweakable parameters.
Let me know if you need to know anything else. Still at a loss.
