Thank you for your nice comment! It includes a bit of a difficult question, so it's not a definitive answer.
Major 8-bit game consoles did not have a reverb function as an audio effect, so I don't think it will be added in that way.
It was common to reproduce pseudo delays, etc. with note data. If we add a feature, there may be a feature that makes it easy.
If we make a 16-bit super version in the future, I think that reverb etc. will be implemented.
The Python library for playing song data was initially released, but as a result of many customizations, it has become unusable for general users At this moment.
There are not many functions other than normal playback, and now intro loop playback is also supported for audio file export, so I don't think there are many benefits.
