Hello there,
I have a question. I'm a choir conductor and I use BIAB to create backtracks for my choirs.
I also use Musescore to create midi files to practise with or create a piano accompaniment.
My question; What would be the easiest playback gear for me?
An iPad. Much software and many apps that let you do what you need. Notion for iPadOS is very good and accepts MusicXML 3.0 from MuseScore. Now that Fender has purchased Presonus, Notion for iPadOS has gotten better and the in-app purchases are less expensive.
I load my singer's guide tracks as mp3s into Dropbox.
I find the idea of buying yet another piece of playback gear silly.
