Positional Sensing
e DRUM
in supports positional sensing for cymbals and pads using the ‘Mesh Center Piezo’
Pad Type. The device can send out a Control Change message (CC) to indicate the
position, or a separate Edge Note.
The CC or Note can be set in Note Panel .
To get positional sensing working, you’ll need to adjust the
Range controls. In the picture on the right, the Range
controls are represented by the green bar, and a red line
represents the positional measurement.
Setup For Mesh Pads
The Min Range control defines the size of the ‘center’ region of the pad. When hitting
directly in the center of the pad or even slightly off-center, the position indicator should
fall to the far right, but as you hit closer to the edge, the red indicator will suddenly jump
over towards the right. The Min Range control should be set somewhere between the far
left and the point where the indicator just starts to jump to the right.
The Max Range control helps define the sizes of the off-center and edge portions of the
pad. As you drag the control further left, the size of the off-center region increases and
the size of the edge region decreases.
If using a dual piezo pad, additional control is available by clicking on the
‘T’ to change it to ‘R’. ‘R’ is for ring, and this control uses information
from the ring piezo to improve stability of off center hits. When the red
indicator falls into the orange rectangle, the measured position is
constrained to be at least 64. Most pads will not benefit from this control
and can usually be left with the rectangle set as small as possible.
Understanding the Positional values
When the pad is hit in the center, the
eDRUM
in
sends a CC value of 0, at the point where
the positional sensing begins to register, it sends a CC value between 64 and 127
depending on how close to the edge you hit.
If you are sending a Note instead of a CC, the
eDRUM
in
will send the ‘edge’ note when
the calculated CC value is greater than 95. You can adjust Range Max control to adjust
the transition point between ‘center’ and ‘edge’.
Setup For Cymbals
There are two different positional sensing algorithms for cymbals. The
first one is designed to support Roland and ATV cymbals, and the
second is a more generic approach that was designed to support the
Lemon 18” Ride and may also work with some other cymbals.
You can switch between the two algorithms by pressing the button
shown in the image on the right.
The rest of the controls work in a similar fashion as described above.
