modulation – n01$3fl00r

To turn feedback on, you have to use the master gain setting in performance mode. Putting that gain in the center position (12 o’clock) effectively turns the image off. Turning the knob to the right adds positive gain, while turning it to the left adds negative gain. When you move past the center point (3 o’clock for positive gain and 9 o’clock for negative gain), you move beyond 100% gain, which introduces feedback. Pressing the center button (B) in performance mode allows the user to toggle between five different feedback modes. Each feedback mode is associated with a different LED color.

Color	Feedback Mode
Red	Regular
Green	Hyper Digital
Yellow	Edgy
Teal	Stable Glitch
Pink	Inverted Stable

You can then also adjust various feedback settings by holding down the center button (B), and adjusting the various silders and dials on the Hypno. I call this Feedback Modulation Mode. Moving the dial on the left (A), adjusts the rotation of the feedback. putting the dial to the left of center causes the rotation to move to the left, while moving it to the right of center causes the rotation to move to the right. Moving dial B adjusts the X offset of the feedback, with the center position being no offset. Thus, moving the dial to the left of center causes the feedback to move to the left, and vice versa. Moving dial C adjusts the Y offset of the feedback, with the center position corresponding to no offset, so turning the knob to the left moves the feedback down, while moving the knob to the right moves the feedback up. The dial on the right (D) adds modulation to the rotation of the feedback, with the center position being no modulation. Thus, moving the knob to the left of center causes the feedback to rotate counter clockwise, while moving it to the right of center causes it to rotate clockwise.

The upper two of the center knobs (dial E) zooms the feedback, with the center position corresponding to a 1:1 ratio. Moving the knob to the left zooms in, while moving it to the right zooms out. The lower of the two center knobs (dial F) creates a hue shift for the edges of the shapes. Because this is related to feedback, this can introduce a gradient effect. The two sliders adjust the amount of feedback that is sent back into the gain of the corresponding shape. Thus, slider A affects the gain of shape A, while slider B affects the gain of shape B. In order to do this, we need to first turn on cross modulation by pressing the button for the current oscillator (button A for oscillator A and button C for oscillator B). While holding this button, tapping the button for the other oscillator will toggle cross modulation on or off. This will be indicated by a green (on) or red (off) LED.

A bit of experimentation is called for here in order to get an idea of what the possibilities are. That being said, making numerous setting changes in feedback modulation mode can be difficult to to undo, so, you might find it useful to restart the Hypno between trying out each of the Feedback modes.

Using the Hypno 5: Using Input Shapes

When you press and hold buttons A or C, they allow you to further change the attributes of the two respective video oscillators. That is by pressing and holding A, you affect the first oscillator, while pressing and holding C affects the second oscillator. The manual for the Hypno calls this Shape Pages, but I will call this Mod Mode, as the settings that are accessed through this method essentially modulate the oscillator. For those of you who are new to the concept of modulation, we can simplify the concept for the Hypno, and state that modulation makes the images move.

When pressing and holding A or C, the functions mirror each other. For instance, when you hold down button A, slider A controls the scrolling of the shape. However, when you hold down button C, you would now using slider B to do the same affect. Thus, when describing various functions, I will try to describe slider and dial positions in relationship to the button being held, while also putting the exact slider or dial in parenthesis in order to be clear.

So, as already stated, the slider on the same side of the button controls the scrolling of the shape (slider A for button A, slider B for button C). The dial that is closest to the button (dial A for button A, dial D for button C) changes the speed at which the shape rotates. The top dial on the same side as the button (dial B for button A, dial C for button C) controls the amount of modulation for polarization or for Y (vertical) scrolling. In the later case, the twelve o’clock position on the dial indicates no scrolling, while moving the dial to the left causes the shape to scroll down, while moving the dial to the right causes the shape to scroll up.

The the top dial on the opposite side as the button (dial C for button A, dial B for button C) controls the amount of fractal modulation. The dial on the opposite side of the button (dial D for button A, dial A for button C) controls the amount of fractal drift, or if fractal modulation is off, the amount of mirroring or repetition. The slider on the opposite side of the button (slider B for button A, slider A for button C), controls the amount of modulation sent the selected oscillator to the other oscillator (A to B or B to A). The top dial (E) sets the color saturation for the selected oscillator (ranging from white fully saturated). Finally, the lower dial (F) sets the hue offset from the root hue setting from performance mode.

As we get further into modulation, it is very possible to make settings in modulation mode that you find difficult to impossible to undo or un tangle. Rebooting the Hypno by turning it off and turning it back on again, can allow you to reset it, but often dealing with the lack of predictability is part of the process. That being said, if you want to feel more in control of the output, change the settings in modulation mode slowly and change only one setting at a time, while noticing the visual change that occurs with that setting change.
