HRESHOLD
With this dial you adjust the velocity threshold from which on the G9 accepts signals sent by the
detecting sensor (voltage). Low thresholds are preferable for sensitive players, but often cause auto
triggering due to vibrations of the environment. Such signals are not desired since they produce
sounds which don´t stem from striking a pad.
The name threshold is always preceded by the name of the active component and it is available
for almost every component, except for Bells (cymbals). Bell and edge sensors work in conjunction
with each other and by adjusting the edge sensor, you automatically adjust the bell qualities.
Threshold parameter value range: 1-127
For piezo inputs: Input threshold level. Sets at what minimum (relative electrical) level a signal will be
detected as a hit. This is one of the main settings affecting overall performance of the drum kit and
the best actual value depends on types of pads used. It may take a while to find the best value.
For switch Rim/Edge inputs: Input Switch threshold. Sets below which level the switch is detected as
hit/pressed. Note that on the switch Rim/Edge inputs actual velocity is derived from the piezo signal
of the Head/Bow input. The best way to set a correct threshold on a switch input is to check the
Pad
Monitor for Choke messages. With a proper threshold value, you should see at least one Choke
message when you press the switch. If detected, these Choke Messages appear as black bars with
a constant velocity value of 127. Depending on the selected Trigger Type and the way pressure is
applied to the sensor, you might observe more Choke messages. If you apply pressure to an FSR
Sensor and don´t observe Choke messages in Pad Monitor, then the Threshold needs to be adjust-
ed. Try to explore the full Threshold spectrum to determine the boundaries between which you
obtain Choke messages.
Bell Threshold is relevant for the for the 3rd zone of a 3 Zone Yamaha-style pad/cymbal. Sets below
which level the Bell switch is detected as hit/pressed. This level must be lower than the Threshold
level of the Rim/Edge input of a switch type trigger (
Edge Threshold ). If the connected pad is a
3Way Roland cymbal, Bell Threshold must be set to 0 to prevent false triggering of Bell notes.
How to proceed:
Strike components detected by piezo elements (e. g. head) as soft as you would normally play and
start with the lowest threshold, rising it gradually until your softest strokes are not recognized in the
Trigger Monitor any more. Then go back 1-2 steps in threshold again. This way you set the threshold
as low as possible and as high as needed. Regarding Switch inputs the procedure works the other
way around. Since switch type sensors already carry a low voltage permanently, the voltage goes
down by pressing/activating the sensor. Increase the threshold gradually and select the highest
threshold that still returns choke messages in
Pad Monitor .
