Batumi II is not merely a common LFO, times four. Instead, it offers four channels of wide-range voltage and tempo-controlled oscillators that may operate independently or in several synchronous modes, scoring 12 simultaneously available waveforms that may be phase offset or frequency dependent with variable ratios.

It is a powerful, versatile, multifaceted modulation hub that may act as the central driving force for any modular patch. Even though it is a digital module, the output waveforms are anti-aliased and then smoothed with adaptive analog filters; hence no digital artifacts should be noticeable.

Batumi II is a second, vastly upgraded revision of the original Batumi, preserving its form factor and layout. It has been internally redesigned from scratch using modern components and it now offers extended range (up to audio rates) with V/oct tracking, a new frequency multiplication mode, and more waveforms (including two types of random).

Features

• Four wide range, VC LFOs
• 1V/oct tracking
• Free, phase, divide, and mult modes
• Twelve simultaneous waveform outputs
• Assignable waves, incl. two randoms
• Easy assignable wave selection
• Per-channel reset and sync
• USB connector for easy firmware updates

Expandability

Xaoc have managed to incorporate the features of the original expander into Batumi II (sync mode switching and assign waveform selection) without changing the size of the module which opened up new possibilities for the new optional expander.

The expander for Batumi II adds multi destination inputs for sine wavefolding, assign output waveform selection or rectangle pulse modulation with the destination set for each channel independently. Poti II also features frequency input attenuation as well as sine and assign output attenuation. All adjustments may be performed separately for each individual channel or for all channels simultaneously.
