Where Can I Find Resources To Make A MIDI Dataset Of Guitar Tablatures?

I’m making a dataset of MIDI files of guitar accompaniment to various melodies. Ultimate Guitar is the only resource I have found for this so far, but it doesn’t actually provide MIDI files for its tabs; in the Pro plan, it provides tab sheets and those must be converted to MIDI with a transcription software. Provided there are no such existing datasets, where could I scrape for these MIDIs?
