If anyone is interested here is level adjustment for all waves, with additional pulse wave reshaper to make it a lot sharper. Trimpots are used to recenter the wave perfectly at 0, as it always bothers me if its slightly off. You can remove the trimpots and replace them with ~242.2K resistor if you don’t care about that.
And here is sine shaper with commonly available parts:
In the following month or two I will release a new module that uses lots of good ideas from other designs with some extra bells and whistles. Like LFO and wave-folder:
