MORPHING PRESET MANAGER

All Mark III Series modules from Industrial Music Electronics come with a standard preset manager interface. This manager is the product of determined user interface research, and the successful solution to a number of modular synthesizer performance questions. The MORPHING PRESET MANAGER enables immediate control and recall of all panel parameters and significantly reduces the number of patch cords required to recreate carefully patched sounds in a live situation. It provides a new dimension of intense sonic transformation suitable for deep sound design or extended performance technique, for when you just don’t have enough cables or limbs to move the controls in the way that your imagination demands.

The interface consists of an OLED display, rotary encoder, CV input, and an attenuator control. The CV input responds to positive and negative voltages. Each module has a setting to limit the operation of the preset manager: for example, the Hertz Donut and Piston Honda oscillators’ managers can operate ONLY on the wave parameters, or on ALL controls including the frequency. The user may prefer to use the manager only as a timbral control, or also as the master pitch control in a sequenced performance. The interface and voltage thresholds are standardized across all Mark III modules, so a simple unbuffered multiple is sufficient to simultaneously drive the preset state of several modules.

PRESET MODE

When activated, the manager engages one of eight active presets. The preset may be selected by turning the encoder or by manipulating the CV input. The controls may be manipulated while this mode is active, and the module’s CV inputs will also respond. To change the data that is stored in the preset memory, hold down the encoder button while moving the control you’d like to change. The eight presets can then be stored to nonvolatile memory that will endure power-downs and firmware upgrades.

MORPH MODE

When Morph mode is active, the managed controls are put under full control of the preset. The CV inputs will still respond to external voltages. Select a “base” preset by turning the rotary encoder: its button and menu settings will become the basic setting for the morph. The Morph CV input (and the attenuator/offset knob) will then morph ALL of the managed knob/slider controls from one preset to the next, operating over the entire active memory. For example, while using a Piston Honda Mark III, imagine the three waveform morphing axes setting a point within a “cube” of waveforms. By enabling the morphing presets, you are traveling in a straight line between each of these points, navigating a 3-dimensional timbral pathway using a single control voltage. This is something that would take several channels of programmed control voltages (and much more time) to repeatably recreate without the preset manager.

OTHER CONVENIENCES

Stored presets may be recalled from nonvolatile backup at any time. The behavior of the CV input and attenuator can be set in several different ways, from the expected attenuator behavior, to offset, to triggered preset advance, to triggered random preset generation. The preset menu provides initialization and randomization functions that work on the sound even if the preset manager is not active. The random generator tactfully selects sound parameters with carefully considered probabilities and awareness of other states of the preset, resulting in a new tone that more often than not sits in a previously unexplored “sweet spot” of the module’s possibilities.
