I am fairly certain the QY70/100 have 16 song and 8 pattern tracks where as the QY700 has 32 song and 16 pattern tracks (48 tracks total)… as well as an extra midi port (or two, I can’t recall).
Absolutely true! Thanks for the correction Eric. I meant the 16 + 8 was on the 100, and I listed it as 700.
