Features and functionality
-
Befaco Dual Atenuverter allows separate offset and attenuation adjustments on each channel, offering more flexibility than Maths or Triplatt which require dual channels for similar tasks.
Source -
The Rampage's toggle switch for range makes it easier to tune as a VCO, compared to Maths, and tracks about an octave and a half.
Source -
The Befaco Dual Atenuverter can offset bipolar waves by +5V or -5V, useful for converting bipolar LFOs to unipolar positive without adding extra modulation sources.
Source
Build quality
-
Some users report discomfort with rough pot textures in WMD products, contrasting with smoother alternatives like XAOC Tirana II, affecting tactile responsiveness during use.
Source
Comparisons
-
Happy Nerding 3xMIA is praised for its size and cost-effectiveness, with cascading channel capabilities offering versatile modulation setups, contrasting with Befaco's more straightforward dual-channel approach.
Source -
Rampage offers more outputs compared to Maths, making it more versatile for some users, despite Maths having additional mixer functions.
Source -
Compared to the 1U Quadratt, the Atenuverter allows simultaneous offset and scaling without needing additional channels, offering greater efficiency in compact setups.

Use cases and applications
-
Blinds provides 4 channels with CV control, ideal for complex modulation needs, whereas simpler modules like Shades are better for basic attenuation and offset tasks.
Source -
The Rampage can be used to smooth out stepped CV from Mimetic Digitalis, functioning effectively as a slew limiter with different rates for rising and falling signals.
Source -
Owners often use the Rampage as a complex modulator by cross-patching end-of-cycle triggers, allowing for self-triggering loops and modulation of oscillator timbre and effects.
Source -
It can be utilized to create PWM from any waveform by patching the audio signal through and modulating the corresponding rate.
Source -
It's noted for taming pitch ranges on VCV Rack sequencers, providing precise control over modulation signals.
Source -
Critical for scaling and offsetting modulation, especially for modules lacking built-in attenuverters, such as certain WMD percussion voices.
Source
User experience
-
Blinds is favored for ease of use and intuitive layout, with bipolar indicator lights enhancing user feedback, making it a staple in many users' setups.
Source
Mods and upgrades
-
For DIY enthusiasts, the Fonitronik Cascade and mxmxmx 3HP_dual_OA offer compact, customizable solutions for offset and attenuation, catering to those willing to solder components.
