When not using input shapes, you may press the same combination of buttons (A & B for oscillator A or B & C for oscillator B) to set some advanced parameters. Some of these are the same as those used for input shapes. For instance, knobs E & F are used to set the luma key maximum (E) and minimum (F) of a given shape. Likewise, the farthest away of the top knobs (knob D for oscillator A and knob A for oscillator B) are used to squash or stretch the vertical dimension of a shape. However, when using the poly shape, this control is used to set the number of sides for the polygon. In this mode the three nearest knobs (knobs A, B, & C for oscillator A and knobs B, C, & D for oscillator B) are not mapped to any parameter.
Again, regardless of which oscillator is being adjusted, the slider on the left (A) performs a crop on the X axis, while the slider on the right (B) performs a crop on the Y axis. However, when the sine or tan shapes are being used, the slider on the left (A) adds extra modulation on the opposite access, while the slider on the right (B) adjusts the waveshape of the modulation.
Here’s a Sleepy Circuits quick guide describing some of the controls available in Advanced Mode . . .

The Hypno has still more features such as Eurorack patching, MIDI control, and presets. Further information can be found out about these features from the Sleepy Circuits website as well as on their YouTube channel.
