That’s a pretty comprehensive list of current arrangers you have, Danny. It’s gratifying to hear how you find the decade old BK-9 still competitive in terms of overall sound and live ‘feel’, given you have most of the latest, greatest!

I’ve been saying for decades that it often is way more than 10 years between arrangers that TRULY take a really noticeable change in live sound and believability. Roland’s ‘live’ sound has always been its strong suit, and it is taking other brands a long time (and a lot more money!) to catch up and finally pass…

While the BK series might be a bit barebones as a true ‘arranger player’s arranger’, there was never a doubt its raw sound was incredibly ‘live’.
