`musicxml-grooves.js` #50

Closed infojunkie closed 2 months ago

infojunkie commented 3 months ago

This cli tool runs through all MMA grooves, and converts them to MusicXML. In conjunction with the groove to MIDI generation API /groove, we can now have a Web-based drum machine that works with the existing musicxml-player technology.

Missing:

Some MIDI drum voices are missing in drums.xml
Some advanced beat timing detection such as triplets and swing are missing in getNoteTiming()
Tests

Here's the latest progress. This file was exported by musicxml-grooves and imported by MuseScore (3.6, because 4.x has broken MusicXML import) without a validation complaint.

JazzWaltzMainA-1

As per the attached log, a number of cases remain to be handled. I think the trickiest is to deal with articulated notes that are shorter than their scored notation, such as staccato.

Getting close... Here's a highly jittered groove, first manually quantized: JazzBasieAQuantized-1

And now automatically quantized against a grid of 16th notes + 8th triplets: JazzBasieA-1

Latest progress in quantization using a (4, 3) grid with optional beat dashed lines on:

JazzBasieA-1

For reference, here's how MuseScore imports the corresponding MIDI file:
