Training on midi

[ep-oi]

I want to train a S4 model on midi, which I already have as discrete events, for example in the form of .csv. How do I create a dataset with which I can train?
In other words, how can I create a dataset consisting of three columns in a .csv files or how can I train such files with python -m train? I would be very grateful to get an answer as soon as possible.

This is what the csv data looks like: 960 | 70 | 0 0 | 70 | 74 120 | 70 | 0 120 | 70 | 70 120 | 70 | 0
