I have a Clavinova CVP207 which has some similarity to the Tyros (without the megavoices but with Natural Piano voices). I owned several Lowrey Genius models (100, 200, 300) in the 80's. Of course voicing is better now, but the Genius models had random rhythm patterns; there were 2-4 patterns for each chord and they alternated randomly, so the auto-accompaniment was never the same. I assume that was borrowed from the MX1 but am not sure. Are there any current Lowrey owners and can they tell us about the autoaccompaniment? On the Yamaha products, the same 2-4 bar pattern repeats endlessly for a given chord. On my old Genius models, there was random variation and the system chose between several patterns. What do those organs do these days?
