MIDI behavior and notes for the Yamaha DTXPLORER drum trigger module.

MIDI Map for Yamaha DTXPLORER Drum Brain

Note: The DTXPLORER has some odd MIDI behaviour. For example, when a drum is triggered, a Note On is sent with the velocity, and moments later, another Note On is sent with a velocity of zero as some kind of note off.

Hi Hat Foot Controller

The Hi Hat pedal sends MIDI CC #4 (Foot Controller).

For me, at least, using the pedal it came with (the Yamaha HH65 pedal), there are three "states":

• Fully Closed (closed with a little bit of force, gives a value of 127 for CC#4)
• Loose/Half Open (closed with light force, gives a value around 56 for CC#4)
• Open (not pressed at all, gives a value of 0 for CC#4)

Programs

The DTXPLORER does send MIDI program change messages when the kit selection wheel is turned. The values are zero-indexed, meaning that the first program (Acoustic Kit) is a program change value of 0, and so on.
