JoMox Resonator Neuronium

   0 reviews  -  1025 views

    This is the first realization of a device with Resonant Neuron Synthesis, called the "Resonator Neuronium".

    The Resonator Neuronium has 6 analog resonant neurons. The net parameters can be programmed by the lefthand structure in form of a hexagon by use of knobs, buttons and LEDs.

    The GECO (Generative Evolutionary Controlled Oscillator) is an oscillator, or rather the stimulus, to excite the analog neural net.This signal is generated by the neuron microprocessor in each individual neuron. The GECO waves or more simply the oscillator sequences are stored and played by internal “DNA codes”.

    The new paradigms of the 21 century are called complexity, order from chaos, self organisation of complex systems, networking and cooperation. From a certain complexity onwards a system is not even the sum total of its parts but a greater whole which shows totally new attributes than its sub structures.

    The Resonator Neuronium has 6 analog resonant neurons. The net parameters can be programmed by the left hand structure in form of a hexagon by use of knobs, buttons and LEDs.

    There are 6 neurons with 6x6 = 36 net connections for one parameter. In order that summation and FM is connected, we have 2x36 = 72 net connections with individual pots for each node.

    Net Programming

    The rotary knobs are touch-sensitive and allow the net links by a simple touch of the metal coated knobs. The intensities of "wi" or amounts are then displayed and edited by turning the respective knob of the receiving neuron. For better understanding, the routed net connection is displayed as a matrix-LED and displayed in the LCD as Tx (transmitter) -> Rx (receiver) value. If you have a summing net connection, LEDs light up green, with FM connections LEDs light up red.

    The loops indicate the self-networking connection of a neuron. As described in the article, one can let the neuron become self oscillating by resonance or let it toggle swing with positive feedback dependent of the sign of the loop value. The menu selection is made by the buttons within the hexagon to let the user not unnecessarily step through awkward menus.

    The menus are:

    Summing Node

    summing input node of the neuron

    Neuron Frequency

    basic frequency of the resonant neuron = cutoff

    Frequency Modulation

    frequency modulation input of the neuron

    Stimulus Recombination

    Recombination of wave segments (DNA) of the stimulus with other neuron's DNA by mating of the DNA

    Stimulus Edit

    Alteration (editing) of wave forms (DNA) of the stimulus of a neuron. Input by knobs at the LCD display.

    Neuron Envelope

    VCA envelope of each neuron with ADSR. Each neuron is led through an ADSR envelope which time-slices the signal and lets it being played from a midi keyboard.


    On the right side there is a 24 character LCD display placed with 6 soft buttons and 2 knobs. The pots at the display are used for different tasks, e.g. input of DNA waveform of the stimulus of a selected neuron. In the menu selection there are different things to be programmed, like e.g. the midi channel, multi mode (ranking of different channels to different neurons), VCA envelopes of the neurons and more. The rest of the keys is used for selection of the preset memory and the switching between main menu and edit menu.

    All analog neurons in- and outputs are lead out through a 25 pin D-SUB connector at the console back. By this you can cascade 2 or more Resonators to a greater network.


    Two audio inputs are available who feed neuron 1 and 4. Thus you can use any kind of external signal to excite the network. So the Resonator becomes a tool for sound processing as well as a sound production instrument.

    Each neuron has an own last stage VCA envelope with its own output. It is imagineable to let the outputs drive 6 single speakers in a room to form a sonic image installation; a sourround 5.1 application could be possible as well.

    The 6 neurons with individual VCA envelopes get mixed again to a stereo mix with an additional VCA envelope. They are sent to the stereo outputs L=left and R=right. The odd neurons are sent to the left, the even ones to the right stereo channel.


    At the back side there is the well-known midi trio to trigger the neuron envelopes and stimuli by an external keyboard or sequencer. Also certain CC controllers can be sent or received for parameter changes and neuron interactions.
