It's a rough recording. Purely a guess, but it sounds like the same instrument on all 3 tracks, and it doesn't sound like a 4-reed single row instrument to me. Maybe a 2-row or 3-row instrument, based on the range (goes to some high range notes on track 3) and the sound of the reeds. Perhaps a 2-reed instrument? Hard to tell if it's 2 reeds per note, or if the player is hitting octaves. The left hand notes are present but hard to hear; doesn't sound like a 1-row left side to me. Songs are in C (1 & 3) and F (2), which hints at a box with 2 rows.
