ROTLFO is an analog LFO Eurorack module with three simultaneous outputs POINTY, ROUND, and SQUARE,. In the default mode these outputs are triangle, sine, and square wave respectively. It has a TILT switch that tilts these outputs. The triangle tilts to a sawtooth and the sine tilts to an unusual Ocean wave. The square wave is tilted to narrow duty cycle.
The rate can be adjusted from 10 times a second (10hz) at max rate to once a second near the far counterclockwise position and even slower at the absolute minimum. Using the SLOW/NORMAL switch in the SLOW position it slows down by a factor of 10 and is 1hz at the max position and far slower in the minimum. Using the CV Rate -5V is the slowest and +5V is fastest rate as it is shifted in the CV input section to 0-10V. The Rate knob also acts like an attenuator for the CV rate input.
ROTLFO is a triangle core low frequency oscillator with a long tailed pair sine conversion. Both of these are usually found in more expensive VCO modules.
