First, my example shows not a fingerstyle piece. The product is not meant for microphone recordings, it is meant for electric guitar in the first place, and works well with many piezo acoustics.
Conversion via mIcrophone is not really supported.
I just showed you can wiggle it to do it anyway. But it is very much dependent on the type of guitar and what you expect from it.
Machine learning is not something that is done on the userside, there is no way to adapt MG to different instruments other than playing that other instrument in such a way that it triggers a bit better.
