Setting the drum key for independent open and closed hi-hat sounds
TIP
[VOICE] Drum Voice selection
In a real drum kit, some drum sounds cannot physically be played simultaneously, such as open and closed hi-hats.
You can prevent drum instruments from playing back simultaneously by assigning them to the same Alternate Group.
The preset Drum Voices have many such Alternate Group assignments to ensure the most authentic, natural sound.
When creating a Voice from scratch, you can use this feature—either to ensure authentic sound, or to create special
effects, where playing one sound cancels out a previous one.
1
Call up the Key Edit display in the Voice Edit
mode.
Refer to step 3 on page 54.
2
Call up the [F1] OSC
3
Press the key which corresponds to "Hi-Hat
Open" and set the Alternate Group to "1."
Determining how the Drum Voice responds when the key is released
TIP
[VOICE] Drum Voice selection
You can determine whether or not the selected Drum key responds to MIDI Note Off messages. Setting the Receive
Note Off parameter to "off" can be useful for cymbal sounds and other sustaining sounds. This lets you have the
selected sounds sustain to the length of their natural decay—even if you release the note, or when a Note Off
message is received. If this parameter is set to "on," the sound will stop immediately when the note is released or a
Note Off message is received.

Press the key which corresponds to "Hi-Hat
Close" and set it to the same Alternate Group (1)
as in step 3.
5
Confirm whether the Alternate Group has been
set properly.
Immediately after pressing the "Hi-Hat Open" key, press
the "Hi-Hat Close" key. Pressing the second key should
cut off the sound of the first.
Since the settings above are included in the Drum
Voice data, store them as a Drum Voice in the Voice
Store mode.
