11.3.1.3 HIGH LEVEL
High (top) level of the input. In conjunction with the Threshold it sets the boundaries of the span of
relative electrical signals to which the MIDI velocity value range (0-127) is mapped. Signals with
relative electrical levels between Threshold and High Level will produce MIDI notes with velocities
between 1 and 127. Any signals with relative electrical levels above High Level will produce MIDI
notes with velocity 127. The further Threshold and High Level are apart the better, provided you can
reliably get MIDI notes with velocity 127 for the strongest hits. Having said that, you will lose almost no
dynamics until when High Level-Threshold<25~38. If you set High Level to maximum (127), and still
easily get MIDI notes with velocity 127 you probably have a very 'hot' pad and you may lose hit
dynamics. Try lowering Gain. If it doesn't help you will probably need to use a voltage divider on the
input.
G9 High Level parameter value range: 8-127
Hint: The High Level value range of the G9 translates relative electrical signals into the MIDI
Value range (0-127). Don´t confuse this range with MIDI velocity. Depending on the strength of
signals a pad produces it is possible to lower High Level below 127 and still reach velocities of
127.
11.3.1.4 SCAN TIME
Minimum scan time for the input. Measured/shown in 1/10th of millisecond. Can be set between 10
and 100 (1 - 10ms). When the G9 detects a signal above Threshold/Dynamic threshold, it will keep
sampling it for the length of the set Scan Time Period before marking the signal as registered and
making it ready to be sent via MIDI. Next, the G9 scans all Trigger Inputs for registered signals again.
The exact system latency (from stroke to sound) consists of the delay from sensor to input, 1 fixed
millisecond for a non-editable Latency parameter (analysis trigger signals), the Scan Time parameter
and the time for the resulting MIDI message to produce the sound in the sound engine. Scan Time
and Latency describe the boundaries of minimum and maximum latency in trigger performance as
follows: G9 trigger latency is at least Latency(1ms) and maximally Latency (1ms) + Scan Time.
Lowering Scan Time will improve latency and may worsen level accuracy. Raising it will worsen
latency and may improve level accuracy.
Generally, for rubber type pads/cymbals setting Scan Time to 20 (2ms) is enough for proper signal
level detection. For mesh-type pads you may need to raise Scan Time to 30~50 - the bigger mesh
type pads the higher Scan Time is required for proper signal level detection.
Scan Time parameter value range: 10-100
11.3.1.5 RETRIGGER MASK
Retrigger period in milliseconds for the input. Determines how many milliseconds must pass after a
previously detected signal for a new signal to be detected - to prevent a 'machine gun' effect or
false triggering due to vibration after a hit. As a threshold setting this is one of the most important
parameters and it may take some time to find the best value. Ideally it should be set as low as
possible and let Threshold combat the 'machine gun' side effect as well as false triggering in first
place. But if even with highest Threshold Levels and dynamic threshold decay times (Dyn Time) you
still get these unwanted effects; you may need to raise the Retrigger Mask level. On DIY pads and
cymbals, good Retrigger Mask values are in the range of approximately 4 to 12 milliseconds. Setting
Retrigger Mask too high will prevent you from doing fast drum rolls.
