Bring Electronic Music To Its Roots With The Make Noise tELHARMONIC 3-Voice Additive Harmonic Synth Module


The tELHARMONIC is a Multi-Voice, Multi-Algorithm synthesizer module named for the music hall considered by some to be the location of the first electronic music concerts. It was coded by Tom Erbe with the goal of presenting three historically important pioneering electronic tone generation techniques less often implemented within the modular synthesizer.

The tELHARMONIC's roots go back further than the advent of electronic music, as it also takes a new approach to handling music theory in the modular context. TONIC, INTERVAL, DEGREE and D-GATE, allow for patch-programming of complex chord progressions, scales, melodies and playing styles. This Voltage Controlled Music Theory guides the Algorithms in a unified way, whereas CENTROID, FLUX and H-LOCK sculpt the timbre of each Algorithm uniquely, allowing for complex sounds to be created around a unified melodic structure and pattern.


  • 3 Voice Additive Harmonic synthesis inspired by Thaddeus Cahill's Telharmonium, 1897
  • Noise synthesis inspired by early computer music piece "Analog 1: Noise Study" by James Tenney, 1961
  • 3 Voice Phase Modulation synthesis inspired by early commercial digital synthesis, 1980's
  • CENTROID, FLUX and H-LOCK animate each Algorithm uniquely
  • All Algorithms available simultaneously at their respective outputs
  • 6 octaves of continuous 1V/ Oct. pitch control, 4 octaves of quantized pitch control
  • 3 Voice Shift Register allows for creation of any 3-note chord within the twelve-tone scale
  • Voltage Controlled Music Theory!
  • DEGREE Modulation able to be synchronized by clock or gate via D-Gate input
  • Gate Out completes the conversation between tELHARMONIC and rest of system!
  • Utilizes High performance DSP hardware with 24bit, 48kHz codec, 32 bit floating point processing
  • Reasonable power consumption
  • Has Spiratone inside
  • Pairs well with Optomix
Specifications

  • Gate Output: outputs Gate signal at each change in Degree. DC-coupled, 10V Gate.
  • Gate LED: visual indication of activity at Gate Output.
  • FM Input: input for Linear Frequency Modulation of the tELHARMONIC core. Modulates all 3 Algorithms (N, H, and P Outputs). AC coupled; expects maximum signal level of 15Vpp.
  • N Output: output for the single-voice Noise Algorithm. Pitch set by Tonic and Degree and bandwidth set by Flux. Does not respond to Interval, Centroid, or H-Lock. AC-coupled, 8Vpp signal.
  • H Output: output for the three Voices of the Harmonic Algorithm. Core frequency is set by Tonic and Degree. The pitch spacing (harmonic relationship of the three voices to one another) is set by Interval and Degree. Timbre of this Output is controlled by Flux, Centroid, and H-Lock. AC-coupled, 10Vpp signal.
  • P Output: output for the three Voices of the Phase Mod Algorithm. Core frequency is set by Tonic and Degree. The pitch spacing (harmonic relationship of the three voices to one another) is set by Interval and Degree. Timbre of this Output is controlled by Flux and Centroid. Response to Flux is the inverse of that of the N and H Outputs. Does not respond to H-Lock. AC-coupled, 10Vpp signal.
  • Tonic Panel Control: adjusts the pitch of all Voices across 6 octaves.
  • Tonic CV Input: unity, 1V/Octave pitch control Input. Not quantized. Range 0V to 6V.
  • Interval Panel Control: sets the pitch spacing of the three Harmonic and Phase Mod Voices to form Triads (with two Inversions), Fifths, Unison, or Octave relationships. Continuously variable, aside from the two Inversions for Triads.
  • Interval CV Attenuator: bi-polar attenuator for Interval CV Input.
  • Interval CV Input: control signal Input for Interval. Range 0V to 5V.
  • Color Staff: Toward the center of the tELHARMONIC there is a visual indicator that changes color to display the state of Interval and Degree, while pulsing to show the frequency of the Tonic.
  • Degree Panel Control: quantized note selection, relative to the pitch as defined by Tonic. Also determines sonority of the Triad where applicable.
  • Degree CV Attenuator: bi-polar attenuator for Degree CV Input.
  • Degree CV Input: control signal Input for Degree. Quantized parameter. Range +/- 2V.
  • D-Gate Input: Gate Input for activation of Degree parameter. Normalled High so that with nothing patched, Degree is always active. Requires a Clock/Gate signal of at least 5V and width of at least 10ms. 
  • Centroid Panel Control: Centroid has a different effect on the N, H, and P Outputs:
  •     H OUT: modulates or selects harmonics for emphasis by Flux and H-Lock parameters.
  •     P OUT: sets the Phase Modulation Ratio.
  •     N OUT: has no effect.
  • Centroid CV Attenuator: bi-polar attenuator for Centroid CV Input.
  • Centroid CV Input: control signal Input for Centroid. Range 0V to 8V.
  • H-Lock Button/LED: With Flux greater than 10%, sets the Harmonic selected by Centroid parameter to be locked ON. Multiple Harmonics may be locked ON. LED brightness indicates the number of Harmonics locked ON. To un-lock Harmonics, set Flux to 0% or [HOLD] the H-Lock Button for one second until the H-Lock LED fades Off. This paramater only affect the Harmonic Algorithm.
  • With nothing patched to D-GATE:
  •     [HOLD] for 5 seconds to find the {Spiratone}; [HOLD] to return.
  •     [HOLD] for 2 seconds to enter {Shift Register}; [HOLD] to return.
  • H-Lock Input: Gate Input for setting Harmonics to be locked On. Requires a Clock/Gate signal amplitude of at least 5V and a width of at least 10ms.
