Poti II

A 4 HP expander for the Batumi II quadruple LFO. Three miniature pots attenuate, for the channel picked by CHANNEL SELECT, its FRQ·PH·RTO CV input, its SINE output and its ASGN output, and the module remembers each channel's values and its own ASGN waveform through a power cycle. Four SHAPE inputs, one per channel, each with a three-way switch, fold the sine, sweep the ASGN waveform or modulate the rectangle's pulse width.

Key features

• CHANNEL SELECT: picks channel A, B, C, D or all four, shown by Batumi II's slider LEDs
• FRQ·PH·RTO CV, SINE OUT and ASGN OUT attenuators per channel, remembered with a mismatch LED by each pot
• A separate ASGN waveform per channel, set with Batumi II's WAVE button
• SHAPE A to D CV inputs (±5 V), each switched to SINE (wavefolding), ASGN (wave selection) or RECT (pulse width)
• Connected and powered through Batumi II's expander header, never the bus board
