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.

Features

• 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
