I am using the most up to date version of FL Studio and Vital. Upon initially opening up Vital, everything seems to be running smoothly. But I start to run into problems as soon as I minimize it and reopen it. The only way I can reopen any given vital synth on my channel rack again is by closing FL Studio and reopening it. Which is completely out of the question. Here is an image of how Vital appears after reopening it after having minimized or closed it. (mind you, Vital runs just fine on my computer when it is working so I do not think this is an issue regarding my PC.)
Are you using any scaling in FL Studio or Windows ?
Are you using the VST 2 or VST 3 version? For the time being I recommend using the VST 2 version.
For the record Vital opens just fine here in FL Studio.
I think this issue only occurs on the scaled version of FL20. Using the non scaled version right now and everything is running fine. Thanks!
