2HP Modulation CV conditioner (Attenuverter, Offset, Slew Limiter)
2026 Update: 
We released the mark 2 of this module!! With updated features, better usability and better accuracy!
WK2 is a 2HP wide Eurorack compatible dual Attenuverter and CV Utility module.
While channel one just offers scaling and inversion of the input signal, channel 2 also has a simple exponential slew rate limiter and an adjustable offset.
Both channels can have a range of either +/- 1x or +/- 2x. The gain can be set with a switch on the module’s backside.
The Vref used as the offset to channel 2 and the normalled input to channel 1 can be either 5V or 10V. This is also set by a switch on the backside. The offset knob has a range of +/- 5V or +/- 10V respectively.
WK2 mk2 is more accurate than the first version but it is not made for pitch CV precision!!
Switched [normalled] connections:
• Vref (5V or 10V) is normalled to input 1 so WK2 can be used as a adjustable voltage source if no input is patched into it.
• Input 1 is normalled into input 2 so one signal can be conditioned differently for 2 modulation destinations in your patch
• Output 1 is normalled and mixed to output 2, i.e. if Output 1 is unpatched the signal passing thru channel 2 is mixed with the output of channel 2.
Specifications:
• 2HP, wide
• 22mm depth below panel
• Max power: 12V at 30mA and -12V at 30mA
