I purchased two of these a few years ago when building a tactile / touch responsive performance rig. These have now become redundant to my current setups but it is an interesting module if you're looking for hands on performance in your patches. The way you need to apply more skin to the plates to increase to increase the CV amount takes a little getting used to but is a highly expressive method of modulation once you do.

Description from ModularGrid

Touch Controller / Manual Sequencer

Pressure Points is a controller module, an analog sequencer that is played by hand. Touching the gold plated copper wires (aka Touch Plates), you become part of the circuit, generating a gate signal (Gate OUT), a control signal proportional to the amount of pressure applied (Press OUT) and the 3 Tuned Voltages for the activated Stage.

The Gate signals may be used to turn portions of a patch ON/ OFF, generate Timing Events within a patch or to Trigger a Function Generator such as MATHS

The PRESSure signals may be used to add expression to a patch by varying Pitch or Timbre in real-time, based upon the artist's input

The Tuned Voltages may be used to play the Pitch of a sound in a traditional melodic fashion, Program Chords or Timbral shifts (aka Presets)

Up to 6 may be CHAINed together (using CHAIN Cable), to create controllers of varying size and complexity

All outputs are capable of driving a passive 4 way mult without loading effects (no buffered mult needed)

Expansion port allows for sequential control via the BRAINS expander module
