OKAY, before I get shot down in flames for talking rubbish in my last posting!... I've just had a look at my brochures for Technics keyboards:
The KN1000 has 3 so-called 'Rhythm Variation' buttons, in addition to the Dynamic Accopmpaniment, (or D.A.). The brochure describes D.A. as "...an advanced new function(then!)...which detects in BOTH HANDS, how hard and fast you strike the keys..."
The KN2000 has only 1 Variation button, strangely, as well as D.A.
Then, as KN3000 owners know, the now-familiar 4 Variations & M.S.A. arrangement appeared, with D.A. still intact.
I guess, by the time the KN5000 arrived, D.A. was superfluous, due to the reasons I mentioned in my previous reply. The powerful Composer and Sound Arranger allow for far greater flexibility than D.A. ever could!
Any further thoughts?...
