An expressive button similar to the one on an Ondes Martenot

The Softwire Synthesis Press is an expressive button/pressure controller for routing CV in an expressive way. It takes inspiration from instruments like the Ondes Martenot, Therevox & the Analogue Systems French Connection & lets you have that same touch expression in your eurorack system.

From top to bottom:

• Signal input and signal output for channel A.
  Channel A is normalled to internal voltage source.

• Signal input and signal output for channel B.
  Channel B is normalled to channel A input signal.

• Thru input.
  This is summed with the outputs of channels A and B.

• Gate output.
  This goes high when channel A output is high. Threshold is 1.2V

• Bi-polar signal and gate indicator LEDs for channel A, B, and Gate respectively.

• Offset switch
  Selects the offset voltage (5V or 10V) connected to inputs A and B.

• Fade switch
  Selects between Fade or Crossfade modes. In Crossfade mode channel B is inverted.

• Pressure controller.
