1974 Quadruple Low Frequency Oscillator fully voltage controlled 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.
Each of the four channels feature sine, square, and saw waveform outputs, with the saw selectable between saw, ramp, triangle, and trapezoid shapes. The last three LFOs can be connected to the first for interesting modulations, while in Free Mode each LFO functions independently.
Additionally, there’s a quadrature mode that consecutively offsets each LFO by 45 degrees for complex morphing capabilities. The phase offset mode is very similar except that it allows for each slider to control the overall phase amount. In clock division mode, the first LFO functions as the master clock and adjusting each slider increases the clock division.
All of this plus the fact that the module can be configured to work as a powerful rhythmic generator makes the Batumi one of the most powerful modulators in 10HP.
