Many have the same question: why not TOTL arrangers when they do invest in advanced technologies like sound modelling etc. on their high end synths. Earlier, they would incorporate the technology advancements of their other product lines onto arrangers like the multi velocity switched samples of V drums etc. They have SN tones which has great realism like the SA on Yamaha ( SA still has the edge over DNC and SN ) but it hasn't made its way to the arrangers.

Bk-7m is the MOTL TOTL , bk-5 is the TOTL MOTL and bk-3 is the TOTL BOTL

Deane, nice to see you back.
