The wind quartet used in the 8 Squares soundtrack is not a standard quartet, but instead a normal wind quintet minus the flute, so you’re right in not hearing a flute. That instrumentation leaves only instruments that I do play, but what you hear in the game is simply synth sounds. I did experiment with recording the first part of it the way you suggest, but it got a bit difficult and while the “live” recording I have is played more musically and with better sounding instruments it also contains some imperfections and off tune playing so the synth version ended up in the game.

I plan on returning to this score and record a real version of it, but I need more practise with playing together with myself first. (And I need to practice the music, too. When writing it, I took no considerations for it to be easily played. Idiomatic for the instruments, yes, but not easy.)

(The “other games” page contains a listing of what I call the parts in this little quartet. The initial Allegro was inspired by French wind music. The Blues is obvious. Tango Rhythms was an attempt to write a tango based on the “rhythm changes” used in several jazz tunes. The Passacaglia and the Rondo are two more pieces where I used traditional forms. I didn’t make much research though, so the music doesn’t follow the forms or genres that inspires it strictly.)
