I have been using templates in FL Studio from friends that come with instances and presets of Q3 and the only way I can access them is to use the eval. I purchased Q4 a few months ago. Once the eval is gone, how do I access the presets in Q3 using Q4? Is there a way to acquire a Q3 license to use both to make this workflow easier or when the eval is gone am I outta luck?
Thank you,
