After I bought this keyboard, I thought it would be good. But it was not. The sounds are good, and that's all that is good. I thought the 16 tracks Sequencer would be perfect, but no. You can not record in the same key transpose that you have selected in the setup. One can only record tracks in the "Key transpose 0". This means that the 16 tracks Sequencer is useless. After four days, the keyboard has also crashed. Suddenly there comes a sound from an instrument and it does not go away and I have to turn on and off the keyboard with the on and off button. 3 times this has happened now. And there are several bugs in the last OS 1.06. It can not save volume on the tracks when you wish to change a track. I had a major problem to change the volume after it is saved. It retains the old settings and you can not change different settings as volume on a track ex. I do not know if it is always so, but often it happens to me. I bought BK-9 because I wanted to use the 16 tracks sequencer in the right Key transpose during recording, but it is impossible. I have already received answers from Roland. Key transpose works only in playback. Who want it to be so? I think none. I want to say that the BK-9 is not for songwriters at all or on live performing. Songwriters must be able to record the tracks in the right Key transpose, and there are many bugs in OS 1.06. This means that you can not concentrate about music. Instead you concentrating on irritation. Will there be any good music this way? Hmmmm. Not for me, as I want to do it professionally. This is just a useless toy. A keyboard you can throw in the trash. I regret buying this keyboard.
