The author here. Cool. Yes, it's a similar experiment. The difference is that you use Python. I guess from your code, it's a CLI application that talk to MIDI devices and read the data from Sheets. Is that correct?
That’s right, it’s a pretty thin layer. Parses the sheet and schedules the midi to be sent to a particular (virtual) device. Having it all in one place sounds a lot more convenient.
