Envelope Follower

The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source.Converting microphone, instrument, line and modular signals into CV and clock/gate signals, the PI and PI Expand..

Electric Guitar InterfaceInjectr is a fully-equipped electric guitar and bass interface for eurorack synthesizers. The module features an overdrive-capable preamp, versatile amp simulator, and control voltage extractors designed to inject stringed instrument signals directly into the modular environ..

Module A-119 (External Input / Envelope Follower) is designed to allow external audio signals to be integrated into the System A-100. It comprises a pre-amp, envelope follower, and comparator.The pre-amp has two inputs: an unbalanced input for line level signals, with a gain factor of from 0 to 20, ..

VC Performance Mixer Envelope Follower ModuleModule A-135-4C is a four-fold envelope follower with ajustable attack and release time for each channel. The main function of the module is to derive four envelopes from the A-135-4A audio input signals. These voltages can be used to control parameters o..

Quad complex multimode filterThe Tempête Magnétique is a fully analog complex filter/synthesizer module.It was that was created as an evolution of the «Fluctuations magnétiques».More than a mk2, we designed it to push you to play with one of the most interesting things in modular synthesis: to diver..

Pico EF is Erica Synths take on envelope follower module in 3hp! Pico EF features a preamp with +40dB gain (enough to boost even guitar and dynamic microphone signals for use in a modular system), envelope output with adjustable attack time and a gate output with adjustable threshold. The Pico EF ca..

'Cicely' is an “octave fuzz” effect, inspired by the legendary “Octavia” guitar pedal, created by Roger Mayer and most notably used by Jimi Hendrix. There is an interesting history of the pedal on Roger's website here. Cicely adapts the concept for the modular environment, adds some extra featu..

Little Mikey is a mic/instrument pre-amp in an 8HP Eurorack module, providing up to 60dB of exceptionally clean gain.It will provide 48V phantom power to condenser microphones and other phantom-powered equipment, and has a high impedance input option allowing direct connection of e.g. electric guita..
