"the pollen is a compact variable analog noise generator with a few extras. the two main controls are "grain" which helps shape the static, and "pitch" which controls a self oscillating filter that helps to alter the pitch of the static and has a switchable range, high / low. there is also an external audio input with its own volume control and a switch to kill the internal noise source so it will allow the pollen to be used as a distortion box. the output is up to about 7 volts so that it can be used as a control voltage source. the output knob will allow you so turn it down to safe audio level as well.
CONTROLSgrain: gives you control over the static breakup and amount, this control is not very linear so certain setting ranges will change more drastic then others
pitch: this is a control for the self oscillating filter used to alter the pitch of the static, just so we're clear there is not way to use the filter alone or to cause it to not self oscillate
range switch: high / low range control for the pitch
input: this is the audio input volume control, its used to adjust the breakup threshold and lower / quieter settings usually yield more interesting results
output: the output volume
noise source kill switch: this will switch out the noise source inside so that you can use the pollen to process external sources only
power switch: um yeah the power switch
clipping led: shows you when the internal sounds are clipping, usually a good thing. not to be confused for a power led which does not exist.
input jack: mono audio input here
output jack: mono noise out here"
