I would guess I've about 40 or so arrangers... Let's see, three EARLY low-end Yamahas, PSR60, 70... Then PSR6100, 6300, 510, 620, 740, 2000, 2100, 8000, 9000, Tyros, T2, S900, S910, S950, S970.
Technics KN800, 1000, 2000, 5000. Roland G800, G70, E50, E80, BK7m, BK9. Solton/Ketron X1, SD1, SD5, Midjay, Audya, SD7. Korg PA80, 800, 900, PA3X, PA4X, MicroArranger.
I may be finished now.
It would be really hard to justify the price of a Genos, even if I loved it after playing one, because I don't NEEEEED one. Maybe PA5X? ... I'm probably finished though. Maybe . . .
