Insane Probability Sequencing with the Malekko Varigate 8+

video upload by Piotr Garbaczonek

"For this project, I opted to make more of a drum-based piece. I wanted to specifically use the powers of one of the most powerful modules in my system, which is located in the bottom right corner. It's known as the Malekko Varigate 8+. It is an extremely complicated gate and CV sequencer with 8 gate channels and 2 CV channels for pitch sequencing, as well as additional secret digital menu settings like probability, which is an important aspect of my patch. I set my master clock to provide a consistent beat to Varigate 8+. Then I trigger all of the different drum parts from the sampler with the Malekko's randomly produced patterns, so the patterns should not repeat very often, if at all. The fun began when I chose to use this sequencer for all of the components of the composition, allowing me to separate a signal from numerous gate outputs and CV outputs and transmit it to offer pitch and melody to the various oscillators that I used for this.
Mutable Instruments Plaits was the only one that wasn't getting pitch, as it was receiving various modulations that would make it relatively meaningless to input pitch into because the changes created by it wouldn't be as obvious and needed at the moment. Instruō Cruïnn was the single oscillator into which I fed the CV output from Malekko. It is a phase-modulated, stereo oscillator having through-zero outputs that can be stereo, summed, or separate sawtooth outputs per voice. As you change the dispersion of the voices in the module, you get that pitch diffusion effect that becomes more pronounced near the finish of the composition.
During the performance, I am continually altering the number of high frequencies fed into the VCA and pre-effects to keep the stereo feel beautiful and dynamic. Such tasks are generally carried out using my left hand. My right hand is activating all of the different parts of the piece, which aren't necessarily pre-defined because this is an improvised composition, but I have some notion of what I'm going to do before I do it. Only when I need to modify the volume of the stereo oscillator inside the VCA before the 'drop' part of the time stop and then that riser and time start sequence do I use both hands in one activity? Everything comes to a halt when I hit that yellow button because everything in this patch is clocked to a master clock, so if I make it stop, everything stops. I'm also patching something more than a minute in, and it was basically just the output of a slow LFO, which would modulate the knob that modulates the parameters together inside of the Qu-Bit Chance module, which is what I'm using to control the majority of the modulation in this patch, which is changing the fm and cv inputs on two of my oscillators. By randomizing that value, detecting rhythm fluctuations throughout the song becomes even more difficult.

'Moonlight Sonata' - Eurorack Modular Rendition

video upload by Piotr Garbaczonek

"Thanks for watching!
#modular #eurorack #moonlightsonata

This time around all sounds that are being heard, come from the modular system, but the entire sequence is comprised of 4 monophonic MIDI tracks inside of Ableton. Each of the tracks has a CV Instrument plugin from the CV tools package. I am using my Expert Sleepers ES-9, which is a DC-coupled interface, which allows me to send clock data, CV, and Gate outputs directly from Ableton into eurorack modular without a need of a MIDI interface. I am using 4 monophonic tracks because the interface has 8 DC-coupled outputs, which are being used as follows:
1- Gate for melody track 1
The first gate out is going into the first input on the Ornament & Crime Digital Multi-function module in 4 x EG mode, which gives it 4 variable-clock envelope generators with a visual oscilloscope. From there, gate output from o_C goes into Mutable Instruments Plaits as a trigger input. The output of plaits goes through the first channel of Qu-Bit Tone for filtering, and then into the first channel on a quad VCA, and then into the first audio output on the ES-9.
2- Pitch/CV for melody track 1
The first pitch/CV out is going into the 1V/Oct input on the Mutable Instruments Plaits, to control the pitch of it, directly from Ableton’s first monophonic track.
3- Gate from melody track 2
The 2nd gate out is going into the Ornament & Crime’s (o_C) second envelope generator. Then it goes into the Strum input on the Mutable Instruments Rings, which is the 2nd oscillator in this patch. From Rings we have the identical signal patch as on the first track, but on the 2nd channel of each subsequent module. (Filter → VCA → Out)
4- Pitch/CV for melody track 2
The second pitch/CV out is going into the 1V/Oct input on the Mutable Instruments Rings, to control the pitch of it, directly from Ableton’s second monophonic track.
5- Gate for melody track 3
The 3rd gate out is going into the Ornament & Crime’s (o_C) second envelope generator. Then it goes into the CV input on 3rd channel of my VCA: Mutable Instruments Veils. Then it goes right into the audio output 3 on the ES-9.
6- Pitch/CV for melody track 3
The third pitch/CV out is going into the 1V/Oct input on the Instruō Cš-L (Dual Complex Oscillator), to control the pitch of it, directly from Ableton’s third monophonic track.
7- Gate for melody track 4
The 4th gate out is going into the Ornament & Crime’s (o_C) second envelope generator. Then it goes into the CV input on the 4th channel of my VCA: Mutable Instruments Veils. Then it goes right into the audio output 4 on the ES-9.
8- Pitch/CV for melody track 4
The fourth pitch/CV out is going into the second channel’s 1V/Oct input on the Instruō Cš-L (Dual Complex Oscillator), to control the pitch of it, directly from Ableton’s third monophonic track.

Now we get into the surround and miscellaneous modulations, which control the piece’s stereo movement, giving it spaciousness and an emotional feel. The output from Mutable Instruments Plaits is split, the first route is going just like it is described in the first 2 points above. The split output is going into the Mutable Instruments Clouds (which is being heavily modulated by the Divkid øchd module (8 drifting LFO). And then from there, it is going stereo l/r out into the ES-9s extra inputs. The Rings output follows the same convention, as it is also being split, but it on the other hand goes through Instruō Arbhar, and then into Instruō Lúbadh for additional processing. The stereo output from Arbhar is going into the ES-9, and one of the outputs from there is being split to also go into the Lúbadh. (Arbhar is a granular processor, and Lúbadh is a digital 2-track reel-to-reel tape machine)

Additional multi-band compression, EQ, and Limiting are done in the post inside of Ableton on the Bus level to minimize the unnecessarily large amount of processing, for a clear modular tonality.

Cš-L | Episode 01 | The Instruō Ecosystem + Crash Course

video upload by Cinematic Laboratory

"I am not sure how many episodes this series will have, but one episode is definitely not enough. What an amazing module!

In this episode I'll go through the Cs-L in an instruo case and trying to familiarize myself with it. I know many of these modules on their own, but not as a combo and it feels like having two left hands. I simply did not feel 'qualified' to cover a complex module like the Cs-L but I learned a lot while making this video.

I am not in any way related to Instruō except for being a customer. I've been building this case since 2017 and now it's finally almost finished."

Cèismōgraphy | Using Cèis as a wonky drum machine

video upload by Cinematic Laboratory

"The Instruō cèis is an analog CV controlled ADSR envelope generator. It's designed with east-coast synthesis in mind, where you press a key on the keyboard, hear the sound rising to its decay stage, drops to - and holds the sustain stage as long as you press the key - and the release stage starts when you let go of the key. This only works when you send in a gate. If you'd send in a trigger, there can't be any sustain. Now the cèis has a gate CV output for every stage. The gate is high as long as a stage is active. It also fires a trigger at the beginning of the stage, giving you NINE cv patchpoints to play with. But I am not an east-coast fan, I go west. So today I wanted to see how far I'd get if I treated it as a four stage function generator, and added a second one for fun (actually a typical east-coast design has an ADSR for the VCA and one for a filter so there's a good reason to have two)."

I made a 20-minute soundscape video that sounds like the 70s and 80s depiction of music from outer space. Everything is coming out of the Blue Marvin's stereo output, as I don't have any VCAs. Here is the list of modules I used and how they play into the function of the piece:
- Neutral Labs Pip (Clock and CV output)
- Instruō Harmonàig (Quantizer (random melody generator in A Phrygian))
- Instruō/Divkid øchd (overall modulation to a bunch of parameters around the patch)
- Black Corporation Deckard's Voice (Main oscillator on the eurorack side)
- Serge by Random*Source Variable Q VCF (Filter to which Deckard'd Voice is connected (VC F and VC Q parameters modulated by øchd))
- Neutral Labs Nijel (Drive effect for Oscillator 3 in Blue Marvin 2600's Sine Wave, the amount is modulated by øchd's slowest LFO)
- Behringer Blue Marvin 2600 ( 1st and third oscillators, various modulations and internal spring reverb)

In Ableton, I have Valhalla Shimmer on, Other Desert Cities by Audio Damage, and some light EQ and compression.

"Thanks for watching! #modular #eurorack #ambient
In this episode of 'Ambient Explorations', I am using the recently-released Instruo Cruinn, which is a wonderfully sounding stereo through-zero phase modulated oscillator. All the stereo elements that repeat over time, which are sawtooth waves, are coming from this module, in case you wanted to know what it sounds like. It is being supported by its fellow family members: Instruo Arbhar for stereo granular elements; Instruo Lubadh, which is receiving the summing output from Cruinn, and slowing down or speeding up randomly by being modulated by Instruo/Divkid øchd; Instruo CS-L, which is going through Mutable Instruments Clouds to create a nice yet weird background texture (it sounds like people playing violins in the higher register); and Instruo Lion which is taking care of most of the modulation routings within the system.

cruïnn is an all analogue stereo oscillator and the cnōc is a highly compact powerhouse of a function generator."

Video Playlist:
Instroducing: Instruō - cruïnn and cnōc
Instruō - cruïnn Overview *This video heavily features stereo patch examples. For best results use both ears*
Instruō - cnōc Overview

The Instruō cruïnn is an analogue stereo oscillator that utilises through-zero phase modulation to create deep, animated textures.

On top of its single sawtooth oscillator core, cruïnn produces five additional parallel phase-displaced sawtooth variants – each controlled by their own discrete internal triangle waveform LFO. With both on-board and external control over the LFO rates and modulation depths, cruïnn effortlessly creates, super-super-super-super-super saws, lush pads, phasey basses, and chaotic effects.

With cruïnn’s included passive 4 HP Expander, access to all six waveforms are available. Add to that the ability to individually displace the phase of each waveform via CV and cruïnn becomes an amorphous swarm of harmonically rich sawtooths.

• Stereo and summed outputs
• Six phase-displaced sawtooth variants
• Five internal triangle waveform LFOs
• Global rate and depth modulation controls
• Built-in stereo VCA
• Linear and exponential frequency modulation
• LFO functionality
• Includes 4 HP passive waveform and CV expansion module

Cruinn-Expander

The Instruō cnōc is a fully analogue voltage-controlled two stage function generator. This style of function generator was pioneered by the West-coast mindset of sound synthesis and goes far beyond the functionality of a traditional envelope generator. With AR, ASR, and Looping modes, as well as its unipolar positive and bipolar outputs, cnōc finds its home in any patch.

Whether you need a general envelope generator, LFO, delayed gate signal, or a slew limiter to add portamento to your pitch sequences, cnōc fits the bill.

• AR, ASR, and Looping envelope modes
• External control over Attack and Release stages
• Unipolar positive and bipolar outputs
• Assignable gate output
• Manual trigger button
• Slew limiting functionality
• Two response curve settings

video upload by Piotr Garbaczonek

"Thanks for watching and enjoying it!
This project took me a super long time to finish, as I had to transcribe the entire piece by ear and then split the midi into individual monophonic tracks so that my MicroMidi Module from Intellijel can record each layer one by one.

For each layer, I ran uMIDI directly into Mutable Instruments Rings and split it into three voices using a buffered multiple 1U module. The first voice was going directly out into VCA, and the second and third were going stereo in and stereo out from Mutable Instruments Clouds, and then into the VCA. The gate was sent out from uMIDI into the TipTop Audio x Buchla Quad Function Generator 281t, and into Strum input on the Rings. Both Rings and Clouds were being modulated by the Instruō/ DivKid Øchd which was sending all the LFOs into a variety of destinations. In Ableton Suite 11, I mixed everything. Adding Shimmer and Supermassive to tracks that needed it as well as FabFilter EQ and Limited for maximum sonic compatibility. Each track was performed separately in regards to the desired dynamics and articulations from the original score which I was referencing, but not following exactly.

Performance // Granular [Tetra] Grid // Instruōctional Patching

video upload by Instruō

"This patch is broken down in depth in my next Instruōctional Patching video which will be live premiering on Sunday 20th February at 6PM GMT.

This is a performance recording of a patch I created while experimenting with The Tetragrid from Manifold Research Centre.
There are several patching techniques used that I have been experimenting with lately that lend themselves well to harmonic patching as well as much more experimental compositions.

Core Techniques:
• Chaotic cross modulation with magnets (Hail the donut)
• Complex circular FM tones from Cš-L
• Rhythmic gating over index ratios, wavefold depth and signal amplitudes
• Granular/reverberant spatialisation using arbhar
• TZFM as tone generator and processor simultaneously
• Harmonic chord voice using Harmonàig/Saïch

The composition is much more aggressive and textural than my usual. Too much caffeine perhaps… or not enough?
I built the patch to be very hands on and immediate for manipulating the voices. The Tetragrid allows for a wonderfully chaotic interaction between its 6 modulation sources. At times things can stabilise and produce musical ostinatos but simply touching the interface will quickly mix up the patterns.

The algorithms defining the cross modulation in both the instances of audio sources and control generators are circular in nature and with dynamic influence over their ratios. They produce very diverse ranges of complex tones and patterns that can naturally stabilise.

A full written breakdown of the patch and access to the patchnotes can be found on the Learning/Patching page on Instruō website:

Instruō Saïch & Soma Pulsar 23

"A short snapshot of a night with Pulsar & saïch.

I am very much loving Pulsar and what it brings to the table."

Instruō Chordal Ambient Tape Delay Patch // Instruōctional Patching

video upload by Instruō

Performance video here

"Core Techniques:
• Harmonic chord progression using Harmonàig/Saïch
• Cascaded pitch shifting delay
• Sub-harmonic waveshaping with through-zero frequency modulation
• Rhythmic textural "bird noise" by oscillator cross-modulation

This is quite a dense patch with a lot of subtle modulation and some interesting waveshaping techniques involved. Fundamentally it is a patch using 3 parallel voices as audio sources which are mixed via multiple crossfaders.

The primary voice is the harmonic aspect which utilises a Saïch controlled by a Harmonàig to define the chord progression basis of the composition.
The Harmonàig can either be controlled via CV for preprogrammed/randomly self generated progressions, or can be manually played in Performance Mode.
When a new Root note is defined, the GATE output controls the Cèis ADSR which triggers a cascade of events that influence the patch.
The Cèis envelope output (acting as an AR) sounds the chords through a VCA which routs to the Lúbadh, which is configured as a tape delay.

Various gate and trigger signals from the Cèis clock two S&H modules as well as toggling signal routing for variations in parameters such as interval offsets on the Saïch (which introduces tension tones to the chords), input mix of the Saïch voice between the Lúbadh's decks and varies the index ratio of the Cš-L's complex voice.

There is a parallel bass voice which follows the root of the Harmonàig chord progression and is triggered by the primary voice's ADSR envelope (Cèis).
The tone is produced by the trigger output striking/pinging the I-ō47 filter which is tuned to match the Root of the Harmonàig voice. The percussive tone from the Band Pass output is waveshaped via a tanh[3] channel to restrict its amplitude and add a bit of saturation to the timbre. This signal then modulates a neóni configured in TZFM configuration to act as a waveshaper over the tone.

The High Pass output is converted to an aggressive unipolar positive square wave signal via the AND gate of the eãs. This signal is used in parallel to the TZFM waveshaping to soft sync the neóni at the audio rate of the Root note frequency. This clock signal patched to the soft sync input is toggled on and off via a latching switch (tàin) controlled by the release stage gate output of the Cèis.
The result when the soft sync is engaged is a sub-harmonic introduced to the voice.
As the voice is triggered at each segment change of the ADSR this gives a longer rhymic meter that nicely matches the harmonic rhythm of the composition.

Finally, there is a generative textural voice which sits in the higher frequency bandwidth to serve as a chaotic percussive element somewhere between hi-hats and bird noises. This comes from a self modulated Cš-L. The sine wave of oscillator B is used as the sound source. The resulting tone is gated through a VCA by the OR logic result of oscillator A's PWM voice (inverted at the eãs ~ gate) and the clock pulse of the Lúbadh's left deck. The Lùbadh clock is the stable element in this gating signal as the Cš-L is fundamentally unstable due to extreme cross-modulation.

The cross-modulation is exponential on both oscillators and the wavefolder of oscillator B is used to modulate oscillator A which is in LFO range.
The wavefold depth of oscillator B is modulated in addition to the FM depth via the INDEX control.

For final seasoning, an øchd is used to add additional movement to the patch keeping things more dynamic. Vibrato is added to the Saïch voice using the first LFO from the øchd tunes to ~4-5Hz. This vibrato naturally softens the the voice as it is reverberated and echoed in the Lúbadh."
