Flow of Pad Messages
The trigger signals sent from the pads connected to input jacks 1 to 16 and the HI-HAT
CONTROL and FOOT SW jacks are treated according to the settings of the current drum kit
loaded in the edit buffer.
Each trigger input is assigned to a specific MIDI note number, and that MIDI note number is
assigned to a drum voice which you can treat in Drum Voice Edit mode.
You can also set MIDI setup parameters for keyboard voices (i.e., non-drum voices) used in
song playback and so on.
Furthermore, you can apply System Effects to complete drum kits and Insertion Effects to
individual voices.
In accordance with all these settings, the voice will be produced in the tone generator
section and output through the OUTPUT and PHONES jacks.
Triggers
When you hit a pad or a drum with a trigger microphone or sensor connected, a trigger
signal is sent to the tone generator section of the DTXTREME and a sound is output. Up to
six voices can be output for each trigger signal, meaning that it's possible to play a chord or
a variety of different sounds from a single pad hit. You can even trigger different notes
(pitches) or voices every time you hit the same pad.
