Before this post, I had never heard nor read of York Bowen. Some York Bowen enthusiast should create MIDI files of some of his public domain works for piano, which could interest others in seeking out sheet music and published recordings.
Due to Bowen's life span, his later works would still be under copyright. Copyright restrictions are a major factor in preventing the revival in popularity of composers whose works are only partially in the public domain. This swings the advantage to long-dead composers like MacDowell, whose works are completely in the public domain, making trancribing sheet music into MIDI files legal. Although sequenced MIDI is by its very nature crude, it does give a rough idea of what the music is like, and unless people get some idea of the character of a composer's music, they might have little incentive to investigate further.
To put it bluntly, a Google search on "york bowen", "piano", and "MIDI" does not produce much to go on. But "Edward MacDowell", "piano", and "MIDI" calls up my website with its MIDI sequences of 147 MacDowell piano pieces or movements.
