I’ve always been a fan of Roland’s effects architecture. To have two insert effects for KBD sounds and three for the style/SMF Parts was very ahead of its time on the BK9.
Sadly, as with so much with Roland’s during its last few years, there was virtually no use of this in the BK9 ROM styles. They used it a BIT on the EA7 styles, and made a slight use of the multiple Drum Track feature also available (so you could mix and match kits, or have perc on one track and drums on the other) but these features AND the synced audio loops feature were completely missing from the BK9’s ROM.
As I’ve said so many times, the BK9 was a decade ahead of its rivals with its basic features, but Roland didn’t make use of them at all, and missed out on some obvious OS additions, like allowing the Performance to call up saved chord sequences and saved graphics (for sheet music or lyrics), and for the want of a nail, the battle was lost.
I really think this late OS change for the EA7 is probably a nod to EU energy saving regulations to keep legal the sale of the remaining stock. But once again, the EA7 was doomed by almost zero use of its new features (the sampler and the multipads).
It just goes to show, putting a successful arranger together is more than slapping some features on it and saying ‘Here you go, do all the work yourself!’. The arranger market lives and dies by its CONTENT.
