WMD Protostar User manual

1
Hello! Thank you for purchasing the WMD Protostar.
Continuing WMD's tradition of powerful envelope filters,
the Protostar brings some modular synth flair onto your
board with voltage control, high headroom, and patch-
ability.
The architecture of this filter is similar to the Super
Fatman, but with the addition of two and four pole filters
and a notch (resonance down for phaser like effects).
Distortion and noise are lower, headroom is way higher,
but the envelope gives the same natural expressiveness.
This quick manual will get you acquainted with the patch
points, controls, and some baseline settings. Explore all
you want, you can't break it! For more inspiration, check
WMDevices.com for some videos.
As always, any issues, just contact us and we will take
care of you.

Notch Down
High Pass
Band Pass
Low Pass
KNOBS
Attack - How fast the envelope will react
to the incoming signal. Controls both
attack and release.
Threshold - How sensitive the envelope is to the
incoming signal.
Env Amt - Attenuverter that controls how much
the envelope will affect the frequency of
the filter, either negatively or positively.
Resonance - Synonomous with feedback or Q,
this is a boost of the frequencies around the
frequency cutoff.
Freq - Also known as cutoff, this knob’s
position dictates the resting place of the
frequency cutoff.
LFO Rate - Make the LFO go faster or slower
with this knob.
LFO Amt - How much the LFO will affect the
frequency cutoff.
Compression - End of chain compressor squashes
the wet signal to suppress unwanted honks, and
resonant oddities.
Dry / Wet - Amount of unaffected vs. affected signal
coming through the output.
JACKS
Sidechain - Direct input to the envelope follower.
Normalled to the input, use this to have the
envelope follow an external source.
Exp Out - Output for the expression pedal
input. Exp isn’t connected to any control
internally and must be patched.
- Env Out - Always sending +5V until the
envelope is triggered, bringing the voltage
down to 0V and back.
+ Env Out - Sends a CV signal following the
envelope. Signal is 0V to +5V.
LFO Out - Constantly sends the triangle
wave LFO CV signal, reacts to LFO rate knob.
LFO Rate - CV input for control over LFO rate.
Sensitivity adjustable with internal trim pot.
LFO Amt - CV input for control over LFO amt.
Freq - CV Input for control over cutoff frequency.
Feedback - CV input for control over resonance.
Expression Input (back panel) - Plug a TRS
cable from any expression pedal into this, patch
the exp out to what you want to contol, and
express yourself.
