I hear you. As a piano player, I just can't stand the piano sound in my Roland accordion or when driving a piano sound in an external sound source from the Roland accordion. It lead me to believe that they keyboard action(the velocity response and all that) is the source of the problem.

Just wondering if you tried changing the velocity curve.
That might help.

I remember having tried the Roland Fantom-G, and the velocity levels of the sounds were not smooth. Maybe, the BK-9 suffers from the same thing? When I tried the Integra-7 briefly, it seemed to be exhibiting the same "problem". Have you noticed this?

Finally, how does the sound quality of the BK-7m compare to the BK-9?

Thanks.

I recorded two relatively demanding pieces by Brahms and Chopin on it - you can bet I tried everything about the velocity curves to play these as dynamically as possible. The outcome is ok, but I never managed to get piano much less pianissimo, at some point I felt the keys switch from mezzopiano to zero sound abruptly. Playing the CP1 piano on the MoXF yesterday, I managed to differentiate dynamics from piano up to fortissimo quite easily at once.

Sounds like you want an RD800 .... 88 keys granpiano action.. there is so much finesse in that keybed.. it does not have 128 vellocity steps but 128*128=32k..

And it makes a great masterkeyboard as well..

What about the actual sound quality of the BK-9 vs the BK-7m? How do they compare? Is the BK-9 noticeably better? Thanks.

Most of the demos I posted here feature highlights of the BK-9 that are not found in the BK-7m.
- the SN-A piano you can hear in the Chopin Mazurka
- the SN-A trumpet, pipe organ and symphonic strings you can hear in the Händel piece
- the strings again you hear in the 'You only live twice' song (same as in SRX 04)
- the SN-A steel guitars that make the Gipsy Kings tune quite authentical.

The BK-7m pianos are good, too, but the differences with respect to strings, acoustic steel guitar, pipe organs (soft and full) and trumpet are substantial.

Personally I think the Gipsy Kings tune and the Alpine Folk tune 'Trumpet echo' are quite outstanding and sound as realistic as the BK-9 or any current arranger keyboard can get.
Yet, I can achieve roughly the same results if I midi a BK-7m to my Integra and edit thing accordingly.

rosetree ... excellent sounds and excellent playing ... thank you ...

Thanks for your comparison, Rosetree, and your very well-done demos. I always look forward to hearing new ones.

Thanks, Tony & Mike.

I should add that many other sounds like electric guitars, saxophones, ethnic sounds etc. are overall on a comparable level in BK-9 and BK-7m. The only real weaknesses I see in the BK-7m are strings and acoustic guitars. The BK-9 offers some highlights, but of course, these don't go beyond what I already had with the Integra.
The overall package of the BK-9 is really quite appealing, in my case the crucial point to try to sell it (only for a good price) is that I prefer the MoXF to some extent soundwise (and for the better keybed dynamics) and simply don't want to transport two full-size keyboards.
