BELLPULL.KRZ is a small programming example. A K2000 preset (in the Orchestral ROM block) is modified to give it more "bells & whistles", so to speak:
- In Program mode, find the preset called Church Bells. (Note: This preset is present in the ROM-1 Orchestral Block, not in the standard K2000.) This preset plays a single bell "ding". The goal is to add a "dong" to the "ding".
- Press Edit, and use the More buttons to find the DupLayer button, and press it. Layer 1 will be the ding, and layer 2 will be the dong.
- On layer 2, we need to delay the attack, to account for the time it takes the clapper to bounce off one side of the bell and swing over to strike the other side. Change attack segment 1 to approximately 1sec, 0%. This will cause its volume to be 0 for the first second after a key is pressed. Change attack segment 2 to 0.02sec, 100%. The .02 is the smallest time you can dial up; if we leave the ramp time at 0, the second attack segment is entirely disabled, so we choose the smallest nonzero value instead.
- Use the More buttons to find the ENVCTL command, and go to that page (still in layer 2). Choose a value like 0.800x in the upper left entry, which is the attack segment key tracking. The result of this is to increase the 1sec attack delay on the lower notes, and to decrease the delay on the higher notes. This simulates the shorter swing of the clapper in smaller bells.
- Use the "more" buttons to find the Pitch button, and go to the Pitch page (layer 2). Change the Fine Hz to -27ct or so. This makes a difference between the sounds of the 2 "sides" of the bell, and also simulates a bit of Doppler effect, where the bell swinging toward you sounds slitely higher in pitch, and the bell swinging away from you sounds slitely lower in pitch.
- Find the F1FRQ page (layer 2). We want the "dong" to sound a little muffled, because the clapper won't strike quite as hard on the rebound. Adjust the frequency downward from F2 87Hz; i used E2 82Hz, but you can find a value experimentally: Turn the dial counterclockwise while you keep playing a note, until the sound drops drastically in volume (that's too far). Then keep playing and turn clockwise until the sound gets back to a more normal volume, but not as brite as layer 1. Somewhere in there should do the trick.
- optional step: Find the Layer page (layer 2) and set the IgnoreRelease parameter to ON. This allows you to trigger a note and release it immediately, but the second layer will still play after the 1sec delay. This is an optional step. If you leave this parameter OFF, you can hold a key down to play both the ding and the dong, or you can release the key immediately to play only the ding.
- alternative step: Another way to choose ding & dong is by velocity. On Layer 2, the LAYER page, set the LoVel parameter to f. Now a bell will only "dong" if you use force when "pulling on the bell rope".
Note that the mod wheel makes the bells sound more distant, which is a feature found in the preset.
You can toll a few bells at once, but keep in mind that with only 24 voices in a K2000, you'll soon run out.
