Erica Pico RND is combined LFO/random source module.
It generates sine LFO waves, white noise, S&H CV and some interesting stuff – random triggers and pulse wave with random duty circle; basically, everything, you need, to bring some uncertainty in your modular setup.
Sine and pulse LFO with manually controlled frequency
Pico Voice from Erica Synths is amazingly versatile sound source just in 3HP. It features 8 sound generation algorithms: Karplus Strong, Chords, Wavetable, TB303 bass-line emulation, PWM, Supersaw, Wavefold and Harmonic saturation, with three adjustable parameters per algorithm and CV control over one user defined parameter. Despite the small size, Pico Voice sounds bigger than it is!
