Odessa is an addition-type digital oscillator module that can produce various tones by superposing various harmonics.
Harmonics can add dissonant non-integer harmonics as well as integer harmonics, and all harmonics change with the fundamental frequency. By manipulating the parameters of the harmonics, we have succeeded in creating a very wide range of tones, from classic sawtooth waves and sine waves to sounds with strange overtone structures.
Odessa is equipped with macro controls such as the number of harmonics, frequency distribution, and size, and changes in those parameters are displayed by 12 multi-color LEDs. The harmonic series can be densely or broadly spread in frequency, or can be biased, and the tone can be changed by a mechanism such as a comb filter. You can also make sounds like flanging and fading by moving the reaction of the comb filter.
Pitch can be controlled by 1V / Oct, and FM has both exponential type and through-zero linear type. In addition, thick unison is possible by copying and detuning the sound up to 5 voices. Expander Hel can be used to send individual 1V / Oct signals as well as unison to generate codes.
