Roland now primarily concentrates on the Pro market with only entry level arrangers being aimed at the Home Hobby Player, (They have even dropped the Atelier range as well as any TOTL Arrangers) and before anybody starts moaning that arrangers get a bad rap, the sales to pros are miniscule compared to Workstations, Synths etc. as it always has been.
The BK7m module used the technology that was being developed for the G90 (The G70 replacement) before it was shelved by Roland and TOTL Arrangers ceased, the rest of the BK line was taken over by Roland US (The Europe arm was either winding down or had already gone) with all the products being made in China.
As to the future then sales of traditional keyboards that most SZ members are used to are dying out (The next decade will be their Swan Song) as the younger generation don’t want them, so expect something new to come along that will also have remnants of the past. (The way development has always gone)
