Batumi V1 comes with the Poti expander included!

Batumi is a fully voltage controlled, quadruple digital LFO module with a slew of interesting and user-customizable features. Each oscillator can be used independently or in one of 3 synchronized modes: quadrature, phase and divide. For each oscillator, there are sine, square and assignable (saw, ramp, triangle and trapezoid) waveform otputs available. Voltage control is possible for each oscillator’s frequency, reset, and external sync (“tap tempo”).
The total frequency range spans from 28 hours in voltage controlled divide mode, up to 500 Hz.

Poti is a simple but very useful breakout expander for the Batumi quadruple LFO module by Xaoc Devices. Its panel provides an immediate access to the Batumi functions originally selected by the cluster of jumpers on the back of the module: Reset/Sync mode option and selection of the assignable waveform.
