I go along with that definitely. On average I bring down reverb levels on drums to approx. 15-25 and bass even zero.
As to the acc. tracks I generally cut out the reverb ( or most of it) on pianos etc. whereas I am quite generous with strings and to some extent brass,trumpet, sax etc. This was how I started out when programming the PA80 way back in 2002 and only with those ( in itself minor) adjustments, folks would be pleasantly surprised as to what their keyboard was capable of.
Just imagine tweaking most other variables !!!!
