I like the active visualizations and the editing options to shape the curve to one's own desire. Also the up to 10 shapes per plugin instance is great for testing which one is the most suited.
Now, the vertical design is unique but however feels a little incomfortable when editing to be honest (even if it actually gives a better immersion of how the sound is traveling between L and R). Having a metric to time or beats/bars on the x-axis is my preference. I wish there would be an option to swap PanCake to 'horizontal mode'.
Another thing: The text of the parameters and its values as well as some elements are extremely small and very hard to read on modern desktops. And on other location, many space is useless wasted at the interface.
The design in general could also be improved. The modulation to be stronger visible and beat divisions (maybe by numeric values) a little bit better to notice.
After more than 10 years, an update would be really appreciated.
This is a false alarm of your virus scanner (if you downloaded PanCake from directly from our website http://www.cableguys.com/pan-cake.html)
So please disable your virus scanner during installation and turn it back on immediately afterwards.
In general, if you're unsure, you can also upload the file to an online virus scanner, such as https://www.virustotal.com, which checks with a ton of different virus scanners. If only one or two report a virus, then most likely it's a false alarm.
