I have two issues that aren't about FL studio directly, but they're compatibility issues regarding third party VST plugins in FL Studio.
My first issue is regarding Hypersonic. I love this VST to death, but it has major issues with FL Studio. I kept geting errors when trying to save my project, the plugin would randomly stop playing, and I could even lose progress on songs I was working on that used this VST. I googled to see if others were getting the issues I was, and sure enough, there were. There's a "workaround," but all it does is minimize the chances of the plugin going ape shit (and I use the word "minimize" lightly). It's helped me out, but it's not enough. Has anyone figured out a way to get this damn plugin to work properly with FL Studio? I have FL Studio 9, by the way.
The other issue is regarding Dune. It works fine for the most part, except arpeggio programs/presets. They play fine if you use the digital keyboard in the Dune window, but if you try to use them in the FL Studio Piano roll, you don't get any playback. I've searched high and low for a solution on Google but found nothing. I'm not sure if it's the plugin's fault or FL Studio's fault (or mine, even). Anyone else have this issue?
