FSR-4C/B (combo) Quad FSR w/Large Sensors


  • $ 32900


The FSR-4C/B is the first in an upcoming series of FSR combo modules based on the Force Sensing Resistor Controller Core, the FSR-4C. In the FSR-4C/B combo module, this core is paired with the FSR-4B Large Format Sensor array. This provides a larger playing surface that is more comfortable for some to use. With the use of rubber pad overlays, the FSR-4B can also be played with drumsticks and other objects.

The FSR-4C/B in your hands (and soon in your rig) has four identical channels and can produce four independent Pressure Outputs and four separate Gate Outputs. Internal movable jumpers allow any of one the 4 channel Gate or Pressure Output control voltages to be routed to the standard internal CV and gate bus on Doepfer style power bus boards. The FSR-4C/B is a multi-panel module combining the control section (the FSR-4C) with a separate panel of four larger 1.5ヤ square FSR sensors (the FSR-4B). This separate panel is connected via a ribbon cable allowing its placement above, below, or on either side of the main control panel.

The Force Sensing Resistor pressure sensor is a non-capacitance based polymer thick film technology, responding to any direct pressure. They are not affected by skin resistance, are water resistant, and never need cleaning or polishing. As force is applied to the sensor, the deviceメs electrical resistance decreases and the FSR-4C/Bメs circuit converts and scales this resistance change into the Pressure Output control voltage. The Pressure Scale control adjusts this voltage range from 0 to over +10 volts.

The internal Pressure Output is also read (before the Pressure Scale control) by the Gate Threshold circuit and when this voltage passes a level determined by the Gate Threshold control, a gate is produced. At the Gate Output and its corresponding LED will light.

The Force Sensing Resistor is an excellent human/ machine interface sensor. You can even play them by pressing on them with other objects or while wearing gloves. Rubber pads and other textured surfaces can be placed on top of the sensors to add a user defined custom feel to the playing surface.
