When playing the organ you gotta keep it smooth and connected. No more choppy chords
Those "valves" are called Drawbars
When it comes to drawbars I keep it simple. I use:
008500000 (Quiet talk music) Left Hand Chords (you can also add the 2' drawbar)
888800000 Left Hand bass
888800000 008888000 (Same Sound as the previous one, but allows you to play lower on the keyboard)
088800000 (for quick right hand soloing)
658868558 (for old school Hymns) (Add C1 chorus)
888000000 Jazz setting
808500013 hymns
008804004 backing up preacher/west coast style
888880000
008030000
848400012
Sometimes I'll even take out the 8' on some settings and it gives a nice unique sound for backing up the preacher
I do a few more, but the you have to experiment with different settings. I some times add the 1' dawbar or some of the dissonent ones like the 1 3/5? (black ones) ex 808800601 if you use this setting play the left hand chords on the other manual with a softer setting)
You also have to expeirment with playing in diffeent areas of the board with different settings
As for the Leslie switch, you cant just hit it every 2 seconds. When I do hymns I leave it on slow during the verses and switch it to fast during the refrain or chorus.
To get a full sound, you have to play a lot of notes and play in the proper range relative to your drawbar settting and you also have to play bass pedals
Vibrato Chorus settings
I DONT use V/C during talk music. I think its too distracting.
C3 should be used when doing Preacher or house raising chords
C1 can be used when doing hymns or soloing, so you can get that "key click" effect
V1 sounds nice when doing hymns
V3 I dont use to often during service, but I guess it could be used if you are playing an old school shout or doing some funeral music.
