DHO - digital harmonic oscillator card for the Music Easel
DHO stands for digital harmonic oscillator; it has 5, lo-fi, digital sine wave oscillators. The range of the fundamental oscillator goes from 8 Hz to 261 Hz. All 4 harmonic oscillators have independent voltage control over the harmonic level, between 0-100%. These harmonics are the 1st, 2nd, 3rd and 4th overtones of the fundamental. Please note, the 4th harmonic also has a slider, but it is more like an "on-off" switch, but with a slider, you can dial up a "rather noisy sweet spot". The output is 66.9 kHz, 8bit PWM - note, lo-fi, for fun!
Features:
- voltage control for all 4 harmonics and fundamental pitch - manual level control for the main Tini output - sliders for all harmonics and pitch - super lo-fi sound - CV inputs are linear - do not expect here octave tracking - additional "organ" like sounds to your Easel - compatible with all Easels, except the rev1 DIY clone version - hand-built, hand numbered
