The Simple VCO belongs to the same series as the Simple LFO.
It is a very stripped-down version of the Formant VCO, modified and adapted to the Eurorack format.
The Simple VCO is 1V/Oct capable. In order to reduce the number of parts, only one waveform output is available.
It is a very simple module, easy to build, understand, and maintain, yet fun to play and musically accurate.

Piezo is a contact microphone preamplifier and CV generator with an integrated envelope follower, gate output, and user-controllable attack and delay parameters. Its front panel features a dedicated tactile zone designed to be scratched, struck, or pressed, making the module itself a playable instrument.
The AttenuVerter is a dual-channel CV processor. It can attenuate, invert, and offset two independent control voltages.

Input is a Eurorack module designed for pre‑amplifying audio signals from instruments such as guitars, microphones, and more.

The 3 x Passive Attenuator is an older project that offers, as its name implies, three independent passive attenuators. This very simple module is extremely useful when you need to reduce the amplitude of a signal that would be too strong for another module, or when sending a Eurorack-level voltage to a more sensitive, non-Eurorack audio equipment.

The Simple VCF was an early attempt to replicate the low-pass/high-pass filter from the original MFOS Sound Lab Mini-Synth.

The passive OR module is the perfect tool to merge gates and triggers from multiple sources (e.g., sequencers, LFOs, clocks, dividers, or other modules) to create complex rhythmic patterns.
MIDI 1-to-8 is a MIDI/TRS 1 input to 8 outputs splitter/through for Eurorack.

This is a Moog-inspired Voltage Controlled High-Pass Ladder Filter clone, based on the High Pass Filter by EFM (Electronics For Music).
