Make Noise Telharmonic

Note: The Spiratone and tELHARMONIC are included in the same module. To access the Spiratone, have nothing patched into D-Gate and Hold H-Lock for 5 seconds.

The Telharmonic from Make Noise is an ode to synthesis history. In implements digital models of three classic early electronic tone generation techniques. The first one is a 3-Voice additive harmonic synthesis engine that is inspired by the development of the Telharmonium (where the module gets its title), invented by Thaddeus Cahill in 1897. The second is modeled after a computer program written by James Tenney at Bell Laboratories in 1961. This synthesis model was made to generate fluctuating noise bands. The third synthesis engine is a classic Phase Modulation modeler, as used in many commercial digital synths from the 1980s. 

Telharmonic also has another approach to generating Harmonic Motion in the Eurorack realm. The Tonic, Interval, Degree, and D-Gate controls allow for creating complex chord progressions with patch logic and modulation. Such a “music theory generator” is lacking in modular synthesis, and this fills that role while also providing fresh and interesting timbres.
