Re: Help needed creating sessions
The Procyon can do 2 kinds of sound entrainment. Isochronic beats which are pulsing tones or binaural beats.
To do isochronic beats, you need to select one of the color channels in the Sound Modulation dropdown menus. The default setting for these is None. Change each one to Red for instance and the Frequency settings of the Red channel will be the 'speed' at which the tones pulse. Change to Green and Green controls the speed. You can make a different setting for Left and Right but it is recommended to keep them the same most of the time.
Binaural beats are created when the tone in the Left and Right channel have different Pitch settings separated by a small amount. Usually you will want this separation to be same as the Frequency setting in one of your color channels.
You will also want the Sound Modulation menus set to None, so that the tones do not pulse. The 'pulsing' from binaural beats is a perceptual illusion created by the difference between tones as heard in each ear in headphones.
It is simple arithmetic to figure out what the settings in each channel should be.
Say that the Red channel Start Frequency is 10 and the base Pitch in the Start Left audio channel is 175. That would mean that to produce a binaural beat the Right audio channel would be set to 175+10 = 185.
You add the Frequency to the base Pitch to get the pitch setting for the binaural beat offset.
If the Red channel End Frequency is 3 and the base pitch in the Finish Left channel is 175 then the Finish Right Pitch will be 175+3= 178 .
Tell me if this makes sense now.
