Not nearly often enough. But they're both weighted, they're both legendary, and I love them both dearly. One's a K2500XS I got for $1200 back in like 2002 (it still has the $9,999.95 Guitar Center pricetag on the bottom) and the other is a Roland A80 I found abandoned at a Guitar Center for like $90 back in 2011. The K2500 has moved with me like four times, down to LA and back.
Of the three Internet shows I mixed last year, I'd say I created about seven music cues. And when I have time and can give myself the space, I just sit there and space out and play.
