How to create a Ganzfeld
The easiest way to create a Ganzfeld display is as follows:
1.
Set the amplitude of the color channel(s) to 0.
2.
Set duty cycle and phase to 127, and the frequency to a low
value (frequency is not used in a Ganzfeld, and a low value mini-
mizes processor load).
3. Vary the the DC offset between 127 (minimum brightness)
and 255 (maximum brightness).
You can also create a pseudo-ganzfeld by setting the frequency
to its maximum value, which appears unflickering to most peo-
ple, and varying the brightness. The triangle and sine settings
provide the best results in this case.
DC Offset: Creating waveforms that flicker and clip
DC Offset allows you to mix unflickering (ganzfeld) light with
flickering light. The normal setting for this is 127; setting it to a
higher value moves the waveform “upwards”, meaning that as
the setting grows larger (up to 255), the light remains on at what
would normally be the “off” part of the waveform. The closer
to the maximum value of 255 you set it, the more ganzfeld-like
the lights will be.
Though space does not permit a further treatment of this topic
in this User’s Guide, we cover it in detail in the documentation
for the Procyon Editor software, available at
You can also post any comments, suggestions etc. on the Pro-
cyon User’s Forum at that site.
May your Procyon experience be blissful!
