Overview
Choke play
Choking (pinching) the cymbal’s edge with the hand
immediately after hitting the cymbal makes the sound stop.
Choke the location of the edge sensor shown in the figure. If
you choke an area where there is no sensor, the sound does
not stop.

For a snare drum, the tone will change naturally as you move
the strike location from the center of the head toward the
rim.

With certain ride sounds, playing position will change the
nuance of the sound.
Broadly speaking, the TD-20X consists of a controller section,
sound generator section, and sequencer section.

Controller section
This consists of the pads and pedals on which you perform.
When you strike a pad, it outputs a “trigger signal.”
The trigger signal is input to a TRIGGER INPUT jack on the rear
panel of the TD-20X, and is received by the sound generator
section.
Sound generator section
This section produces the sound.
It receives trigger signals from the controller, and plays the
instruments (instrumental sounds) accordingly.
Signals from the sequencer can be used to play patterns, and
MIDI messages from an external MIDI device can be received
to play sounds.
Sequencer section
This section records the performance of the controllers, and
sends the recorded performance data (patterns) to the sound
generator section.
MIDI messages recorded on the sequencer can also be
transmitted from the MIDI OUT connector to control an
external MIDI device.
