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.
So I'd start by looking for a datasheet or library for it (quick google search turns up this repo) and then I'd start by trying to get some debug output.
you can get a ploopy nano which runs qmk, which has programmable USB midi support. I don't know of anyone has done this exact config before, but people have done midi encoders before. I recommend the qmk discord for more info.
