InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
It hasn't been updated since 2020, and going by this open issue (https://github.com/NFJones/audio-to-midi/issues/11) it seems to be experimental rather than actually usable.
Haven’t tried it but check this out: https://github.com/tiagoft/audio_to_midi
Might be worthwhile checking out Spotify’s basic pitch library.
