High fidelity Synthesizer designed for generating Binaural beats and exploring alternate scales. ~ Tone Generation (additive & precise) Additive waveform generation allows for a softer sound on the high end while maintaining the distinctive feel of these classic waveforms. Additive oscillators are indicated by a lowercase title. ~ saw The additive sawtooth wave is generated by adding all the overtones one through 17. ~ sqr The additive square wave is generated by adding all the odd overtones 1 3 5 7 9 11 13 15 & 17. These two additive oscillators sound a bit smoother on the high end without the near-infinite overtones of their precise counterparts. Uppercase indicates a precise oscillator: ~ SAW Sawtooth Wave, try all SAW waves with some detune & low pass filter for the classic supersaw effect! ~ TRI Triangle Wave, smooth sound, good for pads or lead. ~ SQR Square Wave, good for the classic vintage feel. The precise form is calculated according to the mathematics of their respective equations. ~ Binaural Beats The Binaural Slider to the left of the oscilloscope and will offset the right speaker by the amount of HZ listed above it. This enables the generation and experimentation of binaural beats for scientific and recreational purposes. 8 Currently Available Temperaments: ~ 12 Tone Equal Temperament Standard Tuning with A at 440 Hz ~ 5 Tone Major Just Intonated Major Pentatonic scale ~ 7 Tone Harmonic Just Intonated Arabic double harmonic minor scale ~ 12 tone Just Intonated The twelve tones western listeners are normally familiar with pitched by just ratios and based off a selectable root note. ~ 17 Tone Arabic Arabic Scale Quarter tone Scale, typically 7 are chosen from this set for a modal piece ~ 22 Shruti Indian Much like the Arabic scale often a subset of notes is chosen for a piece. ~ 26 Tone Turkish Turkish Scale ratios provided by Peter Biffin, the spike fiddle maker. ~ 43 Tone Parch Harry Parch was a pioneer in microtonal music and an avid instrument maker. This temperament with a Root note of G and Root Frequency of 392 hz allows parch fans to compose for the chromelodeon on the go.
