8 LFOs 

8 triangle LFOs with relative frequencies and CV control.

Output voltage is ± 5.25v (10.5Vpp).

Upper LFO is the fastest and lower is the slowest one. The frequency ratio between LFOs is approx 3/2 (or 1.5), being at max speed the upper 13.5Hz and  the lower one 1Hz .

The frequency range with the potentiometer is 80-90%.

Negative voltages present at the CV input will stop the oscillation of all LFOs, but the potentiometer it's an offset, which means that will act as a manual frequency control and will also set the voltage range for the CV input, allowing negative voltages when set to max.
