24 Cycle Groups

20. Repeatedly play the same key on the keyboard. You should hear the two

snare drums alternating with each key press.

These two drums were chosen for this example because they are fairly close

in timbre, but they’re probably not even from the same drum set! When

you sample your own drums, the effect is much more believable. Check out

the Protean Drums bank if you want proof.

Cycle 2 (Channel)

21. Change the Source of both voices to Cycle 2 (Channel) and play the

keyboard. Do you notice the difference? The drums now alternate with ANY

key press. Before they only alternated if you played the same key.

Randomize the Drums

22. Now change the Window Range bars so that each voice covers half of the

range, as shown below. One voice’s range extends from 0-63 and the other

from 64-127. It doesn’t matter which is which.

23. Change the Source of both voices to Random.

 An Explanation: A new random number between 0 and 127 will be

generated whenever you press a key. If a voice contains that number in its

range it will play, if it doesn’t contain the random number, then it won’t

play.

24. Play the keyboard. The two snares alternate randomly.

25. If you change the ratio of the Window

Range bars as shown at right, Voice 2

has more chance of being selected.

 Of course you can combine the Cycle Groups with other conditions such as

velocity. As an example, you could have one particular sample that always

plays when the key velocity is greater than 90. Otherwise the three other

(lower velocity) voices cycle. How? In the VELWIN, simply set the three

cycling voices to sound with velocities of 0-89 and the other voice to sound

with velocities of 90 and above.

 There’s no rule that says that the cycling voices have to be the same sound.

You could create an entire keyboard full of crazy random keys if you

wanted. Hmm? That experimental music show is coming up....

 Try routing one of the MIDI A-P controllers to your CC Window. Now the

voices will be selected by the setting of a knob. (Wherever the knob is set at

note-on time.)
