I always loved how new items where displayed on VORC, so I’ll ape that for a bit.

hard plAYer- is an 8 bit tunes hardware player, which allows you to listen to the same melodies you could listen to in some of the 80’s home computers and videogame consoles. In next versions It will also work as MIDI synthesizer. It’s audio sound generator porcessor is the General Instruments AY-3891X the same one that was used in vintage computers like the Atari ST, Amstrad CPC, Spectrum ZX, MSX, Oric, or Colour Genie, and consoles like the Intellivision or Vectrex. The YM-2149 was a Yamaha’s licensed version of this processor.

I am really looking forward to the next update when it will support midi in. As it currently stands, you can play tracks off sd cards.  In the meantime check out a overview of the player or this video of the interface.
