Thank you Abacus! And I'm used to setting up my BK-7m with various equipment. What I was wondering, is how easily and flexibly the various buttons and sliders on the SK1 can be used to control more advanced functions of the BK-7m such as part volumes, registration changes, trigger fills and variations, etc.

I know a Roland A800 Pro MIDI master keyboard would be best for this purpose. But as I said, i really like the feel, and "straight down" vertical depression of Hammond organ keybeds. Triggering arranger chords cleanly often requires pressing two or more keys at EXACTLY the same time. On a lot of synth-action keybeds with keys that are hinged at the rear, my fingers struggle with the difference in leverage between the longer white and shorter black keys. Not so with the SK1 !!
