Facehugger

Analog, addressable, non-linear, 8-stage, chainable, function generator and control module

July 6, 2023: The alpha prototype has been built, corrected, and is fully working. The design has been updated and the next circuit board designs are almost complete. The beta and (hopefully) final PCBs will be ordered this week, and test units should be sent out to testers next week. Contact Flight directly for pre-order and purchase information.

MSRP (assembled): US$295
MSRP (kit): US$220

Outputs up to eight different control voltage levels (levels set by the LED sliders) in a sequence determined by a control signal. Depending on how you use it, it can be a:

• Control Voltage (CV) Sequencer
• Gate Sequencer
• Arpeggio Generator
• Envelope Generator
• Burst Generator
• Low Frequency Oscillator (LFO)

The Facehugger is unclocked, using an internal ramp generator to control the cycling, or you can use any external 0-+5V waveform instead. The Sequence order is determined by amplitude and slope of the driving waveform: if it is linear, the stages will trigger linearly (in order), incrementing with a rising signal, and decrementing with a falling signal. With a non-linear drive signal (like a stepped, or staircase wave), the stages will trigger non-linearly based on the same parameters.

Multiple units can be chained together for longer patterns or for synchronizing to generate chords via a rear chaining header.

The rear Ramp out pin can be used as a synch oscillator, or even

• when using an external drive waveform
• as a separate, fully-controllable LFO with adjustable curvature.

The Facehugger also has a rear expansion header for a separate expander module that provides individual level out jacks, individual gate out jacks, a master Gate in jack, and a ramp out jack (see Expander Milestone below for details).

Edit 20, April: Added phasor/vector function - the step direction changes based on drive polarity. With a bipolar drive signal, the slider order will reverse direction when the drive signal goes + to - or vice versa.

• A positive signal goes 1-2-3-4-5-6-7-8, a negative signal goes 8-7-6-5-4-3-2-1.
• If you have the length set to, say 5, it will be +: 1-2-3-4-5-, -: 5-4-3-2-1.
• A positive-going bipolar ramp from -5V to +5V will have the order 8-7-6-5-4-3-2-1-1-2-3-4-5-6-7-8 (I'll see about avoiding that center doubling).
• This also inverts the addressing: if +4V = stage 6, -2V = stage 3.
