Week 7
Glad that I passed the midterm evaluation! 
In this week I mainly focused on fixing issues mentioned in last week’s code review. Outcomes included a caching system that doesn’t involve too many manual memory management operations, a simplified yet more intuitive user interface (still, inspired by Sound Spectrum), some refactoring, and also bug fixes.
The screenshot above shows the new design of the node, which replaced absolute frequency value with relative factors, added units onto parameters, and placed rarely-used settings into the side bar.
After the last code review, more of the design goals has been clarified. Hopefully I will finish the caching system and be able to continue adding more new features in the coming week.
