Programming The Stack/Alternate [F3] Stk/Alt; Ch (Midi Channel) - Yamaha DTX900 Owner's Manual

Reference
Drum Kit Mode [DRUM KIT]
Programming the Stack/Alternate
The Stack function lets you play several Drum Voices simultaneously by hitting only a single pad, while the Alternate func-
tion lets you play different Drum Voice(s) alternately.
In addition, the Stack function lets you play chords by using pitched Voices (called "Normal Voices" in Yamaha synthesizers)
which can be called up by setting the CH (MIDI channel) to a number other than 10 (this channel is normally used by the
DTX900 to play the Drum Voice) and assigning the Voice number to the corresponding channel in the display called up via
[F6] OTHER → [SF3] MIDI.
Note that the Stack/Alternate parameters can be set only for each Trigger Input Source.
NOTE
• In the internal tone generator of the DTX900, MIDI channel 10 is exclusively used for the Drum Voices. The MIDI messages
generated by your drum performance will be transmitted to the internal tone generator over MIDI channel 10.
Programming the Stack/Alternate
When the cursor is located on the STEP column:

3 4
1 SOURCE (Trigger Input Source)
Determines the Trigger Input Source which triggers the Stack/
Alternate function. You can change the Trigger Input Source
by hitting the corresponding pad when Input Lock is turned
off.
Settings Refer to page 61.
B STEP
Determines the step number of the Alternate function. Only
one Step 001 is preprogrammed in most preset Drum Kits.,
meaning that the Stack/Alternate function is not used.
For example, each of the STEP "001" lines indicates the pro-
gram when hitting the pad for the first time. Each of the STEP
"002" lines indicates the program when hitting the pad for the
second time. Likewise, the rest of the numbers such as "003"
and "004" are the same as above.
When the number of the existing step is changed, the new step
number's line blinks. Pressing the [ENTER/STORE] button
to fix the step number and stop blinking.
Settings 001 – 100
C [SF1] INSERT
Pressing this button inserts a new step at the current cursor
location and increases the numbers of all the already-pro-
grammed steps after the cursor location by 1.
D [SF2] ADD
Pressing this button adds a new step of the same number as
that at the current cursor location without affecting the num-
bers of the other steps.
NOTE
• Up to 100 events for each Trigger Input Source (a total of 500 events
for each Drum Kit) can be entered. An error message appears when
you try to enter more steps than the limitation.

E [SF3] DELETE
Pressing this button deletes the step at the current cursor loca-
tion. If the step number is gone by deleting a certain step, the
numbers of all the already-programmed steps after the cursor
location are decreased by 1.
F [SF4] CLEAR
Pressing this button clears the step at the current cursor loca-
tion without affecting the numbers of the other steps.
G [SF5] CHORD
Pressing this button calls up the different display used when
you enter the Stack program by playing the external MIDI
keyboard connected to the MIDI IN connector. For details,
see page 87.
H [SF6] Input Lock
You can turn Input Lock on or off by pressing this button.
When Input Lock is turned on (the [L] indicator appears at the
top right of the display), the Trigger Input jack 1 cannot be
changed even if you hit any pad. This function is useful when
you want to adjust the parameters of the current pad (con-
nected to the current Trigger Input jack) while hitting other
pads.
The first page when the cursor is not located on the
STEP column:

1 CH (MIDI channel)

Determines the MIDI channel. With the default initial set-
tings, this parameter is set to 10, which is normally used for
the Drum Voice. If you want to play a pitched Voice, set this
parameter to a number other than 10.
Settings 1 – 16
NOTE
• You can assign the Voice to each of the MIDI channels 1 – 16 on the
display called up via the [DRUM KIT] → [F6] OTHER → [SF3] MIDI.
This setting can be performed for each of the Drum Kits.
