Frozen Wasteland VCV plugins

A collection of unusual plugins that will add a certain coolness to your patches.

Quad Euclidean Rhythm

• 4 Euclidiean rhythm based triggers
• CV control of Steps, Divisions and Offset, Padding, Accents and Accent Rotation
• QERs can be chained together to create arbitrarily long sequences.
• If Chain Mode is Boss, the QER runs on start up, then stops if the track's Start input is patched, until a Start trigger is received - basically the first QER should be set to this
• If Chain Mode is Employee, the QER track will be idle until a Start trigger is received.
• Patch EoC (End of Cycle) outputs to next QER's Start Inputs
• Last QER's EoC should be patched back to first QER's Start Input to create a complete loop.
• May want to consider using an OR module (Qwelk has a nice one) so that mutiple QER's outs and accent outs can gate a single unit
• Each QER has its own clock input, so tempo changes can easily be created
• Mute Input keeps rhythm running just no output
• https://www.youtube.com/watch?v=ARMxz11z9FU is an example of how to patch a couple QERs together and drive some drum synths

Euclidean Rhythms

• Euclidean are based upon attempting to equally distribute the divisions among the steps available
• Basic example, with a step count of 16, and 2 divisions, the divisions will be on the 1 and the 9.
• A division of 4 would give you a basic 4 on the floor rhythm
• The Offset control lets you move the starting point of the rhythm to something other than the 1

Quad Golumb Ruler Rhythm

• 4 Golumb Ruler rhythm based triggers
• For when QER is “too danceable” :)
• Features identical to the Quad Euclidean Rhythm and both units can be chained together

Golomb Ruler Rhythms

• Unlike Euclidean Rhythms which seek to evenly distribute the divisions, Golomb Rulers try to ensure unequal distribution
• Basic example, with a step count of 16, and 4 divisions, the divisions will be on the 1,4,9 and 13.

BPM LFO

• Tempo Sync'd LFO.
• CV Control of Time Division
• Pairs well with the Quad Euclidean Rhythm and Quad Golomb Ruler Rhythm
• Hold Input keeps LFO cycling, but Outputs stay at last value

Damian Lillard

• Voltage Controlled Quad Crossover
• Use Sends/Returns to apply FX to different frequency domains of input signal
• Basic example, distort only the mid lows and/or mid highs so your distortion doesn't remove bottom end
• or, apply different delays to create interesting resonances and other FX
• Video of a snare drum being fed into four delay lines: https://www.youtube.com/watch?v=EB7A_hzMpNI
• Use your imagination!

Quantussy Cell

• This is based on work by Peter Blasser and Richard Brewster.
• Instantiate any number of cells (odd numbers work best - say 5 or 7)
• This is what is called a Quantussy Ring
• The Freq control sets the baseline value of the internal LFO
• The Castle output should be connected to the next Cell's CV Input.
• One of the outputs (usually triangle or saw) should be connected to the next Cell's Castle input
• Repeat for each cell. The last cell is connected back to the first cell
• Use any of the remaining wav outputs from any cell to provide semi-random bordering on chaotic CV
• Check out http://pugix.com/synth/eurorack-quantussy-cells/

Mr. Blue Sky

• Yes, I love ELO
• This is shamelessly based on Sebastien Bouffier (bid°°)‘s fantastic zINC vocoder
• Generally you patch something “synthy” to the carrier input
• The voice sample (or I like to think “harmonically interesting” source) gets patched into the Mod input
• Each modulator band is normalled to its respective carrier input, but the patch points allow you to have different bands modulate different carrier bands
• You can patch in effects (a delay, perhaps?) between the mod out and carrier in.
• CV Control of over almost everything. I highly recommend playing with the band offset.

Lissajou LFO.

• Loosely based on ADDAC Systems now discontinued 502 module https://www.modulargrid.net/e/addac-system-addac502-ultra-lissajous
• Each LFO is actually a pair of LFOs (x and y)
• Adjusting them will show harmonic relationship between the two
• Yellow is LFO 1, Blue is LFO 2
• Output 1: (x1 + x2) / 2
• Output 2: (y1 + y2) / 2
• Output 3: (x1 + y1 + x2 + y2) / 4
• Output 4: x1/x2
• Output 5: y1/y2

Seriously Slow LFO

• Waiting for the next Ice Age? Tidal Modulator too fast paced? This is the LFO for you.
• Generate oscillating CVs with range from 1 minute to 100 months
• NOTE: Pretty sure my math is correct, but 100 month LFOs have not been unit tested

Phased Locked Loop (PLL)

• Inspired by Doepfer's A-196 PLL module
• This is a very weird module and can be kind of “fussy”. Recommend reading http://www.doepfer.de/A196.htm
• Added CV control of the LPF that the 196 did not have
• Generally you want to “listen” to the SQR OUT
• You'll want to feed a Square-ish wave into Signal In
• Low LPF FREQ settings create a warbling effect, high = craziness
• EXTERNAL IN overrides interal VCO
• The LPF OUT is normalled to the VCO CV, try patching something in between the two
• Two comparator modes: XOR and D type Flip Flop
• Does not make pretty sounds, but can be a lot of fun.
