Original Batumi and PotiThis is such an awesome module and you can do so much with it very well taken care of lightly used excellent condition.Batumi-5The Xaoc Devices Batumi (Version 1) is a compact, highly precise 4-channel digital Low-Frequency Oscillator (LFO) designed for Eurorack modular synthesizers. Widely celebrated for its deep modulation capabilities, it packs independent and synchronized oscillator features into a skiff-friendly 10 HP module. [1, 2, 3]Key FeaturesFour Independent or Synced LFOs: Each oscillator can function completely independently or be linked in three synchronized modes:Quadrature: Creates staggered, 90° phase-shifted waveforms for dynamic stereo movement.Phase: Channels track the master LFO but with individual, adjustable phase offsets.Divide: Acts as a clock divider, allowing the LFOs to cycle as musical subdivisions (e.g., half notes, quarter notes) of the master. [1, 2, 3, 4, 5]Simultaneous Outputs: The module provides three simultaneous outputs per channel: Sine, Square, and a user-assignable waveform (saw, ramp, triangle, or trapezoid). [1]Zoom Mode: Pressing and holding the center button enters a "Zoom Mode" for fine-tuning frequencies without being restricted by the physical slider position. [1, 2]Firmware Updates: Includes a USB port and a dedicated software application to update and change firmware. Technical SpecificationsSize: 10 HP width, 45 mm deep (skiff-friendly)Power: Requires ± 12V rails; Current draw: 80 mAFrequency Range: 0.01 Hz to 100 Hz via sliders; can be extended via Control Voltage (CV) from 28 hours up to 500 Hz.Connectivity: Voltage control inputs for frequency, reset, and external sync ("tap tempo").Poti-6The Xaoc Devices Poti Version 1 is a 3HP passive breakout expander designed specifically for the original Batumi Quad LFO module. It provides immediate front-panel access to internal functions that would otherwise require manually adjusting tiny jumpers on the back of the Batumi module. [1, 2, 3, 4]Key FeaturesReset/Sync Mode Toggle: Allows the user to quickly switch the Batumi's reset/sync input between a hard-reset (gate) and a tap-tempo (clock division/multiplication) function. [1, 2]Waveform Selection Switches: Enables the user to choose the shape of the assignable waveform (asgn) for all four channels. Users can instantly toggle between saw, ramp, triangle, and trapezoid. [1, 2, 3, 4]No Power Required: Because it acts as a passive breakout board, it draws no power directly from the Eurorack bus and only works when connected to the Batumi.
