Thanks for the info ! I don't know how many drums have stems now in 2024 ?
I know they haven't got around to adding the shots holds pushes in the stems (maybe they were added in the stereo tracks after the artist recorded the drum track ?).
I thought you could use the drum chart midi with the SforzandoVST with the Playable RealDrums .sfz in the DAW to replace any stem track that you can get right or add the missing shots etc...
