This is what you will get with the BK9..
A Juno Stage keybed..
Sound bank from the Jupiter50..
VE series vocal processor..
Independent screens from the BK5..
Most likely they will add..a Drawbar organ (VK) with sliders..
Chord sequencer..
16 track sequencer besides the 8 track style composer..
Benefits will be the mic input with effects and harmony..
76 keys with semi weighted keybed..
The great playback ability of the BK series..
This could be the ideal all in one lightweight keyboard..that many desire..and probally under 22 pounds...
Maybe a street price under 2 G's...(well under).
No...it will not be the replacement for the G70...but most likely a stablemate..
