Telharmonic Additive Synthesizer

Telharmonic Additive Synthesizer

Make Noise

Regular price $2,740.00 HKD Sale


The Telharmonic contains three simultaneous synthesis algorithms which are harvested from the early period of electronic music. There is a Noise Algorithm, a 3-voice Additive Harmonic Algorithm and a 3-voice Phase Modulation Algorithm, each having its own distinct sonic character and strengths. Another highlight is that the synthesis algorithm’s parameters are intended to be highly musical and link directly to music attributes found in music theory. Users can easily modulate these music-theory related parameters such as intervals to create chords, hence sequencing chord progressions with ease – a rare treat in the eurorack world. The Telharmoic can be thought as a 2-in-1 module, consisting of a synth voice and a dedicated composition toolkit.


  • 3x Algorithms (Tuned Noise, 3-voices Additive synthesis, 3-voice Phase Modulation)
  • Simultaneous output of 3 synthesis algorithms
  • CV control of music theory-derived parameters, such as chord intervals
  • Spiraltone Easter egg mode
  • Highly unique, melodic and musical!
