For the most part Neptune is highly stable as both an application and a plugin, however there are some rare use cases that cause Neptune to run less than perfectly. Fortunately, in every such case we've identified solutions to get everything running smoothly again.
For Mac OS X
Issue: The Neptune application is silent, sounding crackly, digital, and in general not good.
Solution: This issue is easily resolved by opening Neptune, clicking 'Options' in the upper left corner and changing the sample rate from 44100 to 48000 and then back to 44100. This resets the Bullseye Audio Cable. Also make sure that the input device is set to 'Bullseye Audio Cable' and the output is your desired output device (mine is called 'External Headphones').
The Cause: This issue is caused by the Bullseye Audio Cable receiving inputs from different sample rates and not being properly reset. Changing the sample rate alerts the system that Bullseye Audio Cable needs to be refreshed.
Issue: The Neptune application is suddenly sounding crackly, digital, and is skipping.
Solution: There are a few things you can do here. The first would be to follow the steps in this video and increase the buffer size using FlexASIO and/or increase the latency of the input and the output. If you still are having an issue you should consider using an alternative ASIO driver like ASIO4ALL.
Unfortunately routing audio between devices on Windows isn't quite as smooth as it is on Mac OSX, however with a little bit of patience and fine tuning the parameters the Neptune Application can run very smoothly on windows.
Issue: Neptune is very CPU intensive and my computer is over heating or slowing down.
Solution: The Neptune spectogram can be quite CPU intensive and has the power to slow down older machines. Neptune is still able to function with the window closed and the spectogram will no longer run.
