Patch Notes #13 - 0-Coast FM

Published on Aug 14, 2016 Voltage Control Lab

"Patch Notes #13 using the Make Noise 0-Coast and it's internal Slope section as an FM synthesis source. Full patch notes in the description!

The drone is coming from the Make Noise DPO final output, which is routed through the MMG and to the Optomix, then to the Malekko Mix4. The wave shape from the drone can be seen on the oscilloscope.

The Make Noise Wogglebug stepped random and smooth random outputs are routed through channels 2 and 3 on Maths respectively, and then each routed to the 1V/Oct inputs on each channel of the DPO.

Three channels from one half of the Malekko ADLFO (in Loop x10 mode) are routed to different modulation functions on the DPO, one to the FM Bus Index, another to the Mod Bus Index, and one to the Shape input. The final output from the set of 3 ADLFO channels is routed to the Angle control input. The Sum output on Maths is routed to control the Optomix, summing the slowly cycling channels 1 and 4.

Tempi is clocking everything, including the Ornament & Crime in Piqued mode, generating Euclidean rhythms sequencing the not so audible kick and snare patterns in the Roland Scooper and Noise Engineering Basimilus Iteritas. The BI is modulated by 3 channels on Pressure Points, also clocked through Brains by Tempi. The drums route through the Scooper and through an internal LP filter, and then back to the Mix4.

Tempi is also running the Malekko Varigate 4, which is sending a repeat randomized and 40-60% note probability for each of 8 steps in the sequence, to th X-clock input on the Make Noise René. The Wogglebug burst output is clocking the Y-clock input, and a looping channel on the Dual ADSR from Intellijel is modulating the Y-CV input. This makes for a hectic 16 step sequence modulating the pitch on Mutable Braids. Of course, Braids is in Meta mode, modulated by the Wogglebug bouncing output. Timbre and Color controls are being modulated by the Malekko Anti-Oscillator and the Sputnik Oscillator respectively.

Braids is routed out to Mutable Ripples, and out from the LP4/VCA output to the Mix4. The DPO modulation oscillator saw output is routed to control the filter cutoff on Ripples, while the audio rate bouncing out from the Wogglebug is modulating the FM input. The VCA is being opened by the leftover channel on the Dual ADSR, which is being clocked by another channel on the Varigate.

The Varigate channel is set to one step, with a note probability of about 50% and repeat random setting of about 50% as well.This setup is creating the glitchy, crunchy percussive noises.

Finally the O-Coast is driven by a 15 step sequence from the Korg SQ1 clocked by Tempi. The SQ1 B channel out is being used to modulate the Overtone function on the 0-Coast. The Slope section output is routed to the Malekko Dual Borg in VCA mode modulated by Envelator (which is triggered by the SQ1 B gate output) and routed back to the FM input on 0-Coast oscillator. The Dual ADSR inverted output it patched to modulate the Slope time. Finally, the stepped random output on the 0-Coast is controlling the Contour decay time.

Everything routed back to the Mix4, and on through Mutable Warps pingpong delay from the Parasites alt firmware (still need some outboard reverb!) with a bit of hand controlled modulation of the delay time and feedback.

Patch Notes #12 - Make Noise 0-Coast Slope Section

Published on Aug 7, 2016 Voltage Control Lab

"Patch Notes for our examination of the Make Noise 0-Coast tabletop modular synthesizer and the Slope section. Patch notes in the description!

The 0-Coast is playing the bass tones, sequenced by the Korg SQ-1, which is synced to Tempi. The stepped random output is routed to the Contour section decay length, and one channel on the Malekko Varigate 4 is triggering the Slope section which is modulating the Multiply section. (This is not the same patch as demonstrated in the corresponding tutorial, but that's gonna happen sometimes.)

Ornament & Crime is being used in Quadraturia mode, receiving CV from the triangle wave output from the Malekko Anti-Osc modulating LFO frequency and the Sputnik Oscillator triangle wave modulating the coupling amount. Output A is routed to the Mod Bus index input on the DPO, channel B is routed to the Slope time on the 0-Coast while channel C is controlling the Overtone amount. The output from the 0-Coast is routed to the Malekko Mix4.

The lead sequence is coming from the QCV output on the Make Noise René in Snake mode (clocked from Tempi) into the DPO. The final output of the DPO is routed through the MMG then to the Optomix as the VCA/LPG. The René X-Gate output is routed Channel 4 on Maths, which is controlling the Optomix on this voice. From the Optomix output, the voice is routed to the Mix4.

The Wogglebug is also being clocked by Tempi, sending the stepped random output to the MMG filter cutoff and the smooth random output to the Shape input on the DPO.

Braids is in Meta mode, generating it's own short envelopes to create a glitchy, high frequency sequence. The pitch is modulated by channel 4 on the Ornament & Crime, Meta mode is modulated by the Mayhem output from the Malekko Anti-Osc, and the sequence is triggered by a channel on Tempi.

The Kick is from the Malekko Dual Borg, Snare is from the Noise Engineering Basilimus Iteritas, Hihat is coming from the noise generator in the Roland Scooper, all sequenced from the Varigate 4 and routed through the Scooper, then back to the Mix4 with everything else. Tempi is clocking Brains and Pressure Points, 2 channels of which are routed through the Doepfer A-151-2 sequential switch (itself triggered by another row of Pressure Points) and routed to an internal low pass filter on Scooper.

From the Mix4 to the Mutable Warps Parasite alt firmware delays (I really need a reverb module) and out.

Patch Notes #11 - Analog Shift Register with Ornament & Crime

Published on Aug 3, 2016 Voltage Control Lab

"Patch Notes in the description! Our musical exploration of the Analog Shift Register function in Copier Maschine mode in the marvelous Ornament & Crime DIY Eurorack module.

The Analog Shift Register sequences are being triggered by Make Noise Tempi into the Tr1 input on Ornament & Crime. A channel of Make Noise Maths acts as the S&H CV source routed through the external influence input on the Wogglebug, then out of the stepped random output into the CV1 input on the O&C. Channel A of the O&C is routed to the Sputnik Oscillator, B to the Malekko Anti-Oscillator, C to Mutable Braids, D to the Tiptop Z3000.

All of the oscillators are in tune, each sending a triangle wave out to the Malekko Mix4, which is routed up to Mutable Ripples filter. Out from the LP4 output on Ripples into a channel on the Make Noise Optomix low pass gate. The filter cutoff on Ripples is modulated by the cycling channel 1 on Maths, which in turn is being modulated by the smooth random output from the Wogglebug.

Another channel from Tempi is used to trigger the Intellijel Dual ADSR, which is modulating the Optomix channel in time with the sequence shifting. Channel C on the Malekko Varigate is routed to retrigger the envelope to add some randomized polyrhythmic action to the chords.

The bass is coming from the Make Noise DPO, receiving a 12 step sequence from the Korg SQ-1 which is being clocked from Tempi. The Final output is routed through the Make Noise MMG filter in low pass mode, and on to another channel on the Optomix, which is being modulated by an envelope on the Malekko ADLFO (triggered by the SQ1 sequence).

A channel from Pressure Points is routed to the external FM in on the main channel on the DPO, with the four steps tuned to harmonically modulate the sequence when that touchplate is triggered.

The kick is coming from the Malekko Dual Borg/Envelator combo, the snare from the Noise Engineering Basimilus Iteritas, and the hihat from the Scooper, both drums routed through the Scooper inputs and out along with the hihat sound. Each pattern is programmed and triggered from the Varigate, which is being clocked and reset by Tempi.

The mix output from the Optomix is routed through the delay in Mutable Warps Parasite firmware.

Patch Notes #10 - Roland System 1M Hidden Oscillators

Published on Jul 31, 2016 Voltage Control Lab

All parts here.

"Patch Notes #10 (check the description for actual patch notes) for the most recent Pulse Tips demonstrating the hidden oscillators in the Roland System 1M Eurorack semi-modular synthesizer.

Mutable Instruments Braids is the source of the pad-like sounds in WTx4 mode, sequenced by the Make Noise René playing back an 8 step sequence. The Timbre is modulated by a triangle wave from the Malekko Anti-Oscillator in LFO mode.

Braids is routed through Mutable Ripples LP4 to VCA mode, with both the VCA and filter cutoff modulated by the two ADSR envelopes on the Intellijel Dual ADSR module.

The bass is coming from the Make Noise 0-Coast, sequenced by the Korg SQ-1. An uncomplicated routing here, the SQ-1 is clocked by Tempi.

Tempi is also clocking René and the Dual ADSR. As well, it is triggering the Malekko Varigate 4, which is playing back the kick/snare/hihat sequences, via the Dual Borg kick drum setup we've explored in the past, a snare from the Noise Engineering BI and a noise-based hihat inside the Roland Scooper.

The kick and snare are routed through the inputs on the Scooper, while the hihat is routed virtually via the Roland Aira Modular Customizer App.

Tempi is also clocking the Sync Trig input on the Scooper, so that the input percussion signal can be sampled, looped and retriggered in time with the other sequences. The drum sequence is sampled and detuned to a lower pitch.

The lead is coming from the Roland System 1M, played live on the KMI Qu-nexus. The System 1M Osc 1 is set to the Sine FM waveform, while Osc 2 is set to the Synced Sine FM voice. Both are passed through the VCF/VCA/EFX signal chain in the synth, and out to the Mix 4 with the other voices and drums. Then routed through Warps running Parasites alt firmware delays for a bit of extra space.

Patch Notes #9 - Quadrature LFOs with Ornament & Crime

Published on Jul 29, 2016 Voltage Control Lab

More here.

"Here's our latest Patch Notes video using the Quadraturia mode in Ornament & Crime as a set of complex modulation sources in the Eurorack system.

Ornament & Crime is sending output A to the Trigger input on Mutable Instruments Braids, clocking the internal envelope in the Bees in the Trees alt firmware. Output C is routed to the Timbre input, while D is sent to the Color in.

The wave shape is set to something like a sawtooth (around +64), with the spread set to around -40. The LFOs are frequency shifted to -128, creating a natural rhythmic relationship between the waves. Phase modulation is also enabled.

Make Noise Tempi is resetting the O&C LFOs at the Tr1 input, while 2 LFOs from the Triangle and Mayhem outputs of the Malekko Anti-Oscillator are modulating the LFO frequency at CV1 and shape spread into CV3. One channel from Pressure Points is routed to control wave shape as well on CV2.

Braids is in Meta mode, modulated at the FM input via the stepped random out from the Wogglebug. The randomization is being influenced by the CV output from René which also has the QCV routed to control the pitch on Braids.

Tempi is clocking everything, including Brains (and Pressure Points), René and Wogglebug, as well as the Malekko Varigate 4 and the Korg SQ-1.

The SQ-1 is sequencing the pitch and envelope on the Make Noise 0-Coast, which is generating the lead. The Slope section output is routed to the FM input on the Oscillator.

The Hihat is coming from the trusty Roland Scooper noise generator patch, triggered by a cycling Channel 4 on Maths. The off tempo cycle is modulated via the Both input using 4 rows on Pressure Points routed through the Doepfer A-151-2 Sequential Switch, creating a 16 step pattern modulating the rate of the cycling clock. This gives the hihat the offkilter feel.

The Kick is coming from the Noise Engineering Basimilus Iteritas. A pattern from the Varigate is routed to the input on the Malekko Envelator. The two positive output envelopes are routed to trigger the module as well as modulate the pitch to give more punch to the attack.

All routed to the Malekko Mix 4 and out through the Mutable Instruments Warps running the Parasites alt firmware to add some delays.

Patch Notes #8 - Korg SQ-1 Eurorack Modulations

Published on Jul 24, 2016 Voltage Control Lab

"Episode #8 of Patch Notes explores the Korg SQ-1 as a Eurorack modulation source, controlling the pitch of the bass on one channel, and wobble rate on the other.

Tempi is clocking SQ1, which has an 8 step sequence with a 2 volt range on Channel A controlling the wobble rate on the Slope section of the 0-Coast. A 4 step sequence on Channel B is controlling the pitch of the 0-Coast Oscillator, which is playing the bass part.

Tempi is also clocking the René, the QCV output of which is controlling the pitch on Braids, while the fluctuating random out from the Wogglebug modulates the FM input in Meta mode, scrubbing through the wave programs. The stepped random output on the 0-Coast is multed and routed to both the Timbre and Color controls on the Braids.

Braids is routed through Ripples VCA output, which is being triggered via Maths Channel 4. The Fall time is modulated by the CV output from René. Channel 1 is cycling in a long triangle shape, and output to the 1v/oct input on the TipTop Audio Z3000. The sine output is routed to the Ripples FM input.

Tempi is also clocking Brains and Pressure Points, modulating the Basimilus Iteritas Decay, retriggering the cycling Slope section of the 0-Coast, and sending 2 rows of PP through the Doepfer 151-2 Sequential Switch. From the 151-2, the sequence is sent on to the Ornament and Crime CV 4 input, which is modulating the channel D Euclidean Fill amount in Piqued mode (also clocked by Tempi).

Ornament and Crime is then routed out to the Envelator, which is modulating both filters on the Dual Borg, to produce the kick drum.

The Sputnik Oscillator and Malekko Anti-Oscillator are generating LFOs and cross-modulating each other, each then routed to modulate the PItch, Morph, Fold, and Spread on the BI.

Trigger sequences for Braids and the BI are coming from the Varigate 4, each with heavily randomized note probability and repeats. All channels are then routed through the Mix4 and on to Warps for some delay magic.

Patch Notes #7 - Lorenz Attractors With Ornament & Crime

Published on Jul 21, 2016 Voltage Control Lab

"Patch Notes exploring chaotic voltages generated by Lorenz attractors using the Low Rents mode in Ornament & Crime, a multi-purpose, open source module for Eurorack modular synthesizer.

Ornament & Crime is sending the Lx1 XORed to Rx1 out from channel A to control the Timbre on Mutable Instruments Braids in WTx4 mode, while channel B is sending Lx1 to Braids 1v/Oct input. Braids is quantizing the incoming signal to a Minor Pentatonic scale.

Channel C (set to Ly1) is controlling the Fall time on Make Noise Maths channel 4. Braids is routed to the Mutable Ripples filter and out from the LP4/VCA output, which is being controlled by Maths.

Tempi is clocking René which is sequencing the bass part in the DPO. The final output is routed through MMG and then the Optomix, all from Make Noise. The X-Gate output from René is routed to trigger two envelopes on the Malekko ADLFO, one routed to control the bass channel on the Optomix, the second triggering the other set of 3 envelopes in the ADLFO.

One of the ADLFO envelopes is routed to the DPO Mod Bus Index, giving the bass a bit of grit and grime here and there. Another of the envelopes is routed to the MMG filter cutoff to shape the timbre of the bass.

Tempi is also clocking Brains and Pressure Points, 5 channels from which are routed to the Pitch, Decay, Morph, Fold and Spread inputs on the Noise Engineering Basimilus Iteritas, which is generating all of the high frequency percussion. Tempi is also clocking the Wogglebug, which is routed to the BI Harm input.

Patterns are being generated by the Malekko Varigate 4, also clocked by Tempi. Channel A is triggering Maths, the envelope controlling Ripples on random steps, about 50% probability of a note each step. Channel B is controlling the BI, with a slightly lower chance per step than channel A. Channel C is the kick drum pattern, which is coming from the Malekko Dual Borg (as seen in a previous tutorial video). Channel D routed to another envelope on the ADLFO, and then to the Strike input on the Optomix, controlling random plucks of the bass, with different note probability per step, and about 50% chance of repeat per step.

Patch Notes #6 - Korg SQ-1 As Eurorack Sequencer

Published on Jul 18, 2016 Voltage Control Lab

"Patch Notes for our recent video on using the SQ-1 as a USB MIDI to CV Converter. However, the SQ-1 is not performing that function here, instead sequencing and clocking the Eurorack system.

The SQ-1 is sending pitch and gate CV from the channel A outputs to the Make Noise 0-Coast, which is playing the 16 step plucky melodic riff. The channel B gate CV out is routed to the Varigate 4, which is sequencing the kick drum generated by the Malekko Dual Borg filter (see our relevant tutorial video).

The Sync Out is routed to the Make Noise Tempi, which is in turn sending clocks to the Make Noise René, Brains, Wogglebug and finally, the Ornament & Crime (in Piqued mode).

René is sending pitch CV to a buffered mult, which splits the signal to the Make Noise DPO playing the bass, routed through the MMG and Optomix, with one looping LFO from the Malekko ADLFO controlling the filter cutoff.

The mult also routes to Mutable Braids in WTx4 mode (tuned a perfect 5th up from the bass) which is playing the chords/pads. Braids Timbre is being modulated by an internal LFO, part of the Bees in the Trees alt firmware.

Brains is clocking Pressure Points and Analog Memory, 5 channels of which are modulating the Noise Engineering Basimilus Iteritas pitch, attack, morph, harm and spread settings, while the Wogglebug is modulating decay and fold amounts, providing the glitchier drum elements.

Another channel from Pressure Points is routed to CV input 4 on the Ornament & Crime, modulating the Euclidean fill amount on the rhythms that are triggering the BI.

All channels are then routed through the Malekko Mix4, and then through Mutable Warps running Parasite firmware in ping pong delay mode.

Aside from the pitch and gate CV coming from the SQ-1, the 0-Coast is internally patched. The stepped random voltage source is multed, and routed to both the Contour decay length and Slope time. The triangle LFO from the MIDI B CV port (see our 0-Coast Hidden LFOs video) is routed to the Overtone input. Finally the Slope output is routed to the FM input on the Oscillator.

Patch Notes #5 - Ornament & Crime Harrington 1200 Mode

Published on Jul 13, 2016 Voltage Control Lab

"Patch Notes from our recent exploration of the Neo-Riemannian chord generating Harrington 1200 mode in the Ornament & Crime Eurorack module.

Tempi is the central clock, first routed to the X clock in on René in snake mode, which is playing back an 8 step pattern. QCV output is routed to CV 1 input on Ornament & Crime as the root note source sequence.

O&C is routed to 3 oscillators, Mutable Braids, Malekko Richter Anti-Oscillator and Sputnik Oscillator, each sending a triangle wave shape through the three channel inputs on the Make Noise Optomix, which is acting as a mixer in this case.

The mixed output is sent to the Make Noise MMG Filter in Low Pass mode and then through another homemade VCA, both modulated by the two envelopes on the Intellijel Dual ADSR.

Tempi is also clocking Pressure Points via Brains, which is controlling chord inversion on the O&C.

Tempi is clocking the Varigate 4 as well, which is routed to trigger a Malekko Dual Borg Filter Kick, a snare in the Basimilus and a hihat in the Scooper. The 4th output is randomizing hits and repeated triggers on the Dual ADSR, to give the chords some more complex rhythmic action.

All of these sounds are mixed through the Mix4, and then through Warps Parasite delays. I think that's it!

Patch Notes #4 - Odd Clocks With Make Noise René

Published on Jul 10, 2016 Voltage Control Lab

"Here's an example of a one of the more popular Eurorack sequencers, Make Noise René, modulating the pattern position using stepped random voltages.

Tempi is routed to the X-clock input on René, as well as a 16th note triplet division clocking the Wogglebug. The stepped random output from the Wogglebug is routed to the Y-CV input on the René.

When the Chaos knob on the Wogglebug is set to zero, the longer notes play back the root position, bass line notes along the X axis (left to right). As the Chaos knob rises, the 16th note triplet stepped random voltages begin to effect the Y axis position, creating the effect of arpeggiation.

Tempi is also routed to the Ornament & Crime, which is generating 24-step Euclidean rhythms to both the hihat and the snare-ish sound (a noise-based hihat from Scooper, and a snare from the Basimilus Iteritas.

Tempi is also clocking the Varigate which is driving a kick drum from Braids. All of the sound generating modules are routed to the Mix4, and then through Warps running a delay from the Parasite firmware.

The 0-Coast is receiving a clock from Tempi as well. The internal stepped random function is mult-ed, then sent to the Overtone and Multiply section inputs. The Oscillator square wave is routed to trigger the Slope section, which is tuned to generate sub-oscillator tones, then Slope output to balance input so the signal can be mixed between the sub tone and the overtone signal.

All parts.

Patch Notes #3 - Karplus Strong with Mutable Warps Parasite

Published on Jul 8, 2016 Voltage Control Lab

"Here's a patch using the Karplus Strong string synthesis patch with the Mutable Instruments Warps Parasite firmware delay modes, based on our most recent Eurorack modular synth tutorial.

Braids is routed through one channel on the Optomix, where it is modulated by an envelope from the ADLFO triggered by Euclidean Rhythms from the Ornament and Crime. The attenuated signal is then sent to Warps to excite the delay. The Karplus tone is being excited using the chord based wavetable mode in Braids rather than a noise source as we heard in the tutorial.

Warps is then routed through another channel on Optomix and then out to a mixer. The VCA is being opened by a channel on Maths, tweaking the decay time throughout.

The kick drum is coming from the Basimilus Iteritas, pitch modulated with an envelope from Maths to give it some punch. Hihat is a noise based signal based in the Scooper. All signals are being rhythmically triggered via the Ornament and Crime, which is in turn being clocked from Tempi. Pressure Points and Brains are used to modulate Euclidean Fill amounts on the three voices.

Tempi also clocking the Wogglebug and X-clock on René, with the Wogglebug stepped random out routed to the Y-CV input. The chaos knob is increased throughout to add some random shifting to the René pattern, which is modulating the delay time on Warps, creating the melodic sequence.

Patch Notes #2 - 0-Coast Hidden LFOs

Published on Jul 3, 2016 Voltage Control Lab

"Here's a patch example using the hidden LFOs and other functions in the Make Noise 0-Coast synth as the main voice, with another Euclidean Rhythm based drum part with the Ornament & Crime.

The 0-Coast is the melodic voice, sweeping between the clean triangle wave shape and the additive, overtone shape from time to time.

The note sequence is coming from the René, which is being clocked by Tempi to the X clock and a slower odd tempo to the Y clock from Tempi via the Wogglebug, which is also sending slewed random voltages to the Y CV in. Then the gate from René is routed to the Contour (ADSR envelope) section, which controls the Dynamics (VCFA). The sustain is turned down in the Contour section, resulting in a basic attack/decay envelope, with the decay time modulated by the triangle wave LFO from the MIDI B CV output (as covered in the related tutorial).

The Slope (cycling AD envelope) section has cycle disabled, and is being triggered at an audio rate by the Oscillator square wave output. The rise and fall times are set to zero, and the vari-response knob is set to exponential, creating an extremely short envelope shape. The Slope output is then routed into the Oscillator FM input. The Stepped Random output is sent through the signal mult to the Oscillator Multiply attenuverter, while the square wave hidden LFO is routed to the Overtone attenuator.

Tempi is also clocking the Ornament & Crime, which is running 3 channels of Euclidean rhythms to a kick in Braids, a snare with the Basimilius Iteritas, and a hihat in the Scooper, with the Euclidean fill amount on each sequence modulated by the three channels on Pressure Points clocked from Brains.

https://www.voltagecontrollab.com/"

Patch Notes #1 - Euclidean Rhythms with Ornament & Crime

Published on Jun 30, 2016 Voltage Control Lab

"Our first patch example using an expanded version of the routing used in our previous tutorial exploring Euclidean Rhythms and envelopes in the Ornament & Crime eurorack module.

All 4 Euclidean Rhythm generators in Ornament & Crime are clocked by the Make Noise Tempi, which is also clocking the Wogglebug and the René X and Y clock inputs (at different rates). René is in snake mode, modulating the X CV in with the Wogglebug S&H output, Y CV by the slowly cycling Malekko ADLFO. Four channels from MN Pressure Points/Analog Memory routed to the Ornament & Crime channels modulating Euclidean Fill values on each respective channel.

The 4 channels of Euclidean Rhythms are routed to: Mutable Instruments Braids in Meta mode modulated by René; the Noise Engineering Basimilus Iteritas in a skin/bass mode playing a short, noisy snare; the Roland Scooper which has a noise-based hihat sound whose length is being modulated by another slow ADLFO cycle; the Malekko Envelator which is triggering/modulating a resonant filter Kick in the Malekko Dual Borg. All mixed through a Malekko Mix 4 and then patched through Mutable Warps running Parasites in ping-pong delay mode.

Rhythm control is almost entirely controlled by the 4 channels of Pressure Points, changing the number of filled steps in the generated rhythms from off up to 32 steps.
