Collider

A physical model of various of shakers and wind chimes (maracas, sleigh bells, bamboo chimes, metallic chimes, etc).

Watch the tutorial:

RIGHT-CLICK MENU:

• Polyphony.

  BUTTON:

• SHAKE shakes the particles. Hold down to continuously shake.

  INPUTS:

• SHAKE gate controls the shake.
• V/OCT center frequency of the particles.
• SPREAD control voltage determines the amount of spread from the center frequency.

  KNOBS:

• C center frequency of the particles in Hz.
• SPREAD sets the amount of spread from the center frequency.
• RND sets the amount of random frequencydeviation on each particle collision.
• PARTICLES sets the number of particles. More particles = faster decay in system energy, less particles = slower decay.

  OUTPUTS:

• V/OCT outputs ±5 volts.
• GATE outputs pulses.
• VEL outputs velocity of entire system.

Cosmosis

A continuous sequencer based on constellations where time can move left->right, right->left, up->down, and down->up.

Click anywhere to add/drag new stars. To remove stars click/drag them out of the dark display area.

Watch the tutorial:

RIGHT-CLICK MENU:

• Polyphony.

  BUTTONS:

• CLR removes all stars.
• POS randomizes positions of stars.
• RAD randomizes the radii of stars.

  INPUTS:

• PLAY trigger starts/stops the sequencer.
• SPEED control voltage manipulates the current speed.
• RESET trigger resets the current sequence position.
• Root note input will accept V/OCT to set the root note.
• POS accepts gate that triggers randomizing positions of stars.
• RAD accepts gate that triggers randomizing radii of stars.

  KNOBS:

If the MODE is set to either Blue or Red, in which case time travels down or up, pitch is taken from the horizontal position of the stars. The left switch is good if you'd like to generate randomness in the pitches, however, if you want more control over the pitch then select the right switch.

  OUTPUTS:

• GATES output pulses.
• V/OCT outputs ±5 volts.

Neutrinode

A unique visual-based sequencer where time moves from the center of the 4 independent nodes out to the connected particles. Can generate interesting rhythmic textures and can be animated so that the textures change over time.

  OUTPUTS:

• GATES and V/OCT output only from the corresponding node color.
• ALL outputs all nodes.

:warning: There are a maximum of 16 particles (for 16 polyphonic channels) per node. However, when using the ALL outputs, there is potential to reach that maximum (16 x 4 = 64) in which case it does voice stealing.

Photron | Photron Panel | Photron Strip

Placing modules adjacent to each other will cause them to blend colors. PhotronPanel and PhotronStrip will work together, however Photron only will blend with another Photron.

Photron

RIGHT-CLICK MENU:

• Processing rate (for those with slower CPUs). Keep in mind, if you slow the processing rate down, it'll help your CPU but the animation will also slow down.

• Lock pattern lock the pattern or let it blend.

  BUTTONS:

• Waveform mode: lines, blocks, or off.

  KNOBS:

  INPUTS:

• TOP 4 inputs (zero volts is default values):

  • CV controls the alignment of block colors which is their rate of change. Higher voltage = more alignment and thus their color velocities will become the same.
  • CV controls the cohesion of block colors which is converging on a single color. Higher voltage = more cohesion and thus their colors will quickly become the same and Photron will look like one color.
  • V/OCT controls the target color for Photron. Blocks will drift towards the target color and hover around it. See the image below for corresponding notes & colors:

Talea

An arpeggiator with polyrhythmic capabilities dependent upon note intervals.

Watch the tutorial:

RIGHT-CLICK MENU:

• External Clock Mode:
  • CV controls bpm (beats per minute) based on the input voltage using this formula: 120 * 2^V.
  • 2, 4, 8, 12, 24 PPQN controls bpm based on the number pulses per quarter note.
  • If the mode is set to any of the PPQN modes, the clock will turn on automatically when it receives a pulse. It will also turn off automatically after it times out from not receiving any more pulses.
• Polyrhythm Mode:
  • Fixed means each note is fixed and centered around middle C (C4, volts = 0.0). This note will take the current tempo of the BPM knob and all other notes are a ratio based on this note/tempo.
  • Movable means that the first note played will take the current tempo of the BPM knob and all other notes are a ratio based on this first note/tempo.

    INPUT:

• EXT is an external clock to control the Talea BPM determined by the External Clock Mode.
• V/OCT takes input voltage.
• GATE input gates when note is held.

  BUTTON:

• on or off
• HOLD will hold pattern. Is overriden when you release all notes and start a new note.
• OCT will add octaves to the pattern:
  • No light = 1 octave
  • Purple light = 2 octaves
  • Blue light = 3 octaves
  • Aqua light = 4 octaves
  • Red light = 5 octaves
• POLYRHYTHM will turn on or off the polyrhythm arpeggiator. If off, Talea acts like a conventional arpeggiator.

  KNOBS:

• large main knob at the top controls the bpm (beats per minute).
• GATE knob control the percentage amount the gate is on.
• the pattern mode controls the order of notes when POLYRHYTHM is turned off. These are:
  • ↑ ascending order
  • ↓ descending order
  • 2x each note plays twice in ascending order
  • ⚡︎ in order of which they were played
  • R random

    OUTPUTS:

• V/OCT outputs pitch.
• GATE outputs gates determined by arpeggiator rhythms.

TUNINGS AND RHYTHMS

When POLYRHYTHM is turned on, the arpeggiator will repeat notes at a tempo based on a specific tuning. For example, the note A440 vibrates at 440 Hz and an octave higher the note vibrates at 880 Hz. This is a 2:1 ratio, meaning one vibrates twice as fast as the other. Rhythms can work like this as well, one rhythm can repeat at a tempo twice as fast as another. Once we start using other intervals that occur in a scale, we can create some more complex rhythms. However, using equal temperament tuning (which is standard tuning for the overwhelming majority of music and instruments in the Western Hemisphere) divides the octave into 12 equal steps which gives us non-integer ratios. So if you play an A and an E (perfect 5th) in equal temperament, you get a rhythmic ratio of 1 : 1.4983070768766815, or 440Hz : 659.2551138257398Hz, YUCK! So to simplify this, I use the natural harmonic series for the ratios. They make nice integer ratios and are a naturally occuring phenomenon. The table below shows the ratios that are use for each interval.
