It's a no brainer to offer a 61 and 76... absolutely we should have a choice...
There is only one answer that really makes any since why Yammi does not do it. Since it is a piece of cake to do. All the logical reasoning doesn't apply.
POLITICS amoung divisions of the company...Maybe some one very high up has drawn a line in the sand. Home keyboards 61 keys only. Be nice if we knew if it was true?? Maybe that's not it, but to me it makes the most sense.
If you want 76, you just have to buy from someone else. Or add a 76 (or 88)MIDI keyboard under the Yammi. Not expensive and works well. I use the CME UF70.
