Befaco VC Slew Limiter
Voltage-controlled glide with shapeable curves
6 HP Eurorack module
The VC Slew Limiter by Befaco is a voltage-controlled slew limiter that smooths transitions between voltages with independently controllable rise and fall times. It is musical in character as a portamento generator, envelope follower, and lag processor, with a Shape control that morphs the slew curve from linear to logarithmic/exponential, adding expressive tonal variation to any CV or audio signal passed through it.
Features
- Independent voltage-controlled rise and fall times via dedicated fader pots and CV inputs
- Shape control morphs slew curve character
- TL074 op-amp based signal processing
- Ferrite bead power filtering on both rails
- 4 minijack patch points: IN, OUT, RISE CV, FALL CV
- NP (non-polarized) capacitor for audio-range slew applications
- Separate rise and fall CV inputs for dynamic real-time control
- Fader-style pots for Rise and Fall time for tactile feel
