Poti II by XAOC Devices is an expansion module for the quad LFO Batumi II. The expander complements the main module with four CV inputs for modulating the waveform of sine or assign or square. furthermore the module acts as attenuator for the CV inputs of Batumi II and can attenuate the outputs of sine and assign. This is especially useful if you want Batumi II to modulate itself with Poti II to get more complex control voltages. The module is designed in such a way that the settings made are retained after the modular system is switched off.
