Xaoc Devices Batumi is a fully voltage controlled, quad digital LFO module in Eurorack format with a number of interesting and user-definable features. Each oscillator can be used independently or in one of three synchronized modes: quadrature, phase and divide. Sine, square and assignable (saw, ramp, triangle and trapezoid) waveform outputs are available for each oscillator. Control by CV is possible for the frequency, reset and external synchronization ("tap tempo") of each oscillator. The total frequency range is from 28 hours in voltage controlled divide mode up to 500 Hz. A zoom mode allows precise adjustments of the frequencies and a USB port and a dedicated app simplify firmware updates.
