Composing with tELHARMONIC 101
The left side of the module allows for patch programming chord progressions, scales, and melodies. It
consists of the TONIC, INTERVAL, DEGREE and D-GATE parameters and the visual indication of the Color
Staff. Although you will find great detail below about the inner workings in the next section, NO
KNOWLEDGE OF MUSIC THEORY IS REQUIRED TO COMPOSE WITH THE tELHARMONIC. These
parameters respond to control voltage just like anything else in your system.
Here are some quick pointers:
- You could think of Tonic as the main Pitch/FREQuency control, similar to the grey knob on a DPO or STO.
It is continuous (not Quantized) and responds 1V/Octave.
- Interval sets the spread of the Pitch/FREQuency between voices in the H and P Outputs. There are three
voices that can be set to Triad, Fifth, Unison, Octaves and anywhere in-between. Whatever Interval is
selected will be maintained when TONIC is manipulated. Unison (about 3 o’clock) has all three voices
set to the same note for behavior typical of a VCO.
- Degree adds or subtract up to two octaves from the base frequency set by Tonic. It has a Quantized
response and also tracks 1v/Octave when the DEGREE CV Attenuator is set Full CW. Because
DEGREE is a Quantized parameter, it has a “musically valid” response to any control voltage used.
- Whenever Degree changes values, a gate is generated and available for use at the GATE OUTput.
- The D-Gate Input operates as a Track & Hold for the DEGREE parameter. With nothing patched, D-Gate is
held HIGH and DEGREE will always be actively tracking the signal patched to the DEGREE CV IN. With
a clock, gate, pulse or trigger patched to D-Gate, the DEGREE parameter will only track the signal
patched to DEGREE CV IN while the D-Gate is held HIGH.
The FM IN is a fantastic way to introduce vibrato and pitch bend to a melody or progression. Patch any fast
control voltage or expression voltage to the FM IN to experiment with this technique.
