The circuitry around the LFO has not changed. So these notes are valid for all versions of the module.

The dimensioning of the voltage divider depends upon the desired attenuation of the rectangle signal. The load of the voltage
divider should be not less that ~ 5k. E.g. 3k+3k would half the level, 3k+1k would divide the level by 4. You may even use a 5k or
10k trimming potentiometer.
