Arlene said "I'm having trouble accessing the drum set so I can play it on the organ. Help would be appreciated." Very well, here goes: As you probably know, you can dial up lots of individual percussion sounds on the PR300/300S and assign one of them to each MIDI piston, two on each manual and two more in the pedal. When the MIDI piston/coupler is on, you will get that sound on every key of the respective keyboard, but since there are only two MIDI pistons per keyboard, you can only have two percussion sounds at a time on that keyboard. The drum sets/kits allow you to have a whole battery of percussion sounds at the same time on a manual or pedal, not just two. Each sound is assigned to a different key, so you could have 61 different percussion sounds on the same MIDI piston. Great idea...but which key activates which sound? The next-to-last page of my 300S manual, the blue page, lists the ten drum kits on one side of this blue page, with their respective Program Change numbers, and notes that you must use Channel 10. Pages 108-109 show what sound you'll get on which key for each of the ten kits. Trouble is, the key numbers don't match a 61-note keyboard like the other handy charts do...hey, Rodgers/Roland, kindly explain how this works... meanwhile, bear in mind that C2 on the chart is bottom C on the keyboard, C4 is middle C, etc. So, for example, if you chose PC1 Standard set or PC33 Jazz set, you will get all the different percussion sounds listed from C2 on up, every time you hit the key assigned to a particular sound. If you trill on bottom D and E, you will get a snare drum roll, etc. Suggested registration: hold SET, press Swell MIDI A piston so it blinks, just as you would when choosing any PR300/300S sound...dial up Program Change 49, dial up Channel 10, dial up velocity/volume (default is 64, medium), press Swell MIDI A again to stop it blinking. Pick your Swell stops, use Swell Unison Off too...couple Swell to Great, pick Great and Pedal stops. Put it all on a General piston. Play right hand on the Great, left hand on the Swell for the percussion sounds (chords for combined sounds, rhythmic arpeggios for one-at-a-time). You still have Swell MIDI B plus the other MIDI pistons available for other sounds. Have at it...hope this helps!
