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."

Aeolian harmonic patch in stereo, with wavefolding and TZFM // Instruōctional Patching

video upload by Instruō

"Core Techniques:
• Harmonic chord progression using Harmonàig
• Audio rate XOR voice combination
• Rhythmic modulation
• Wavefolding
• Through-zero frequency modulation

I explore quite a few techniques in this patch. The foundation is a minor chord progression built around a diad patched in stereo (root left and 3rd right).
I wanted to use similar timbres for the voices producing root and 3rd. The root comes from the wavefolder output of a Neóni which is modulated by a rhythmic LFO.
The 3rd is a TZFM pair pitched from the Tš-L modulating a second Neóni. The index ratio is modulated by a second rhythmic LFO.

Self patching an øchd produces the rhythmic LFO signals that become the natual tempo and feel of the patch. I play the progression manually from the Harmonàig as the rhythms are not rigidly locked.

The 5th output of the Harmonàig controls a Tòna from which the square wave output is combined with the root Neóni's squarewave via the XOR comparator on the eãs.
XOR processing of square waves is mathematically the same as ring-modulation/4-quadrant multiplication of the two square wave signals.
Sidebands are produced resulting in a richer more complex tone. As the chord voicings mostly form a perfect 5th interval between root and 5th, the resulting signal remains tonally stable. Slight detuning of the 5th allowing for beating to broaden the timbre.

I low-pass filter this new voice and share it equally between left and right to form a common mono signal for the patch.


The gate from the Harmonàig triggers an ADSR from the Cèis. TRIG mode is engaged to force completion of the attack phase.
This envelope modulates two aspects of the same signal.
The top voice of a Cš-L acts as an LFO. This LFO frequency is controlled by the envelope while the signal's depth is simultaniously controlled by the same envelope.
The processed LFO controls the cutoff frequency of the I-ō47 which is low-pass filtering the XOR signal.
When a note is played on the Harmonàig the filter cutoff will "wobble" with a dynamic rate and depth."

Instruō Introduces Neóni Through-Zero FM Eurorack Module

Instruō - Neóni Overviewvideo upload by Instruō | To learn about Through-Zero Frequency Modulation specifically, Skip to 56:52.

FM with tonality! At its core, the Instruō neóni is a traditional analogue oscillator. What sets it apart from other oscillators in the Instruō product line is it’s Through-Zero FM functionality with AC and DC coupled operation. Add that to its precision soft sync and directional hard sync modes, nonlinear wavefolding, internal modulation routings, and you end up with the most tonal FM sounds imaginable.

Unlike traditional FM, where an oscillator momentarily stalls as negative voltage pulls its frequency down to 0 Hz, neóni inverts the polarity
of its waveforms until positive voltage pulls it back through 0 Hz.
This behavior allows for complex waveforms with less non-harmonic sidebands. Less clang, more bang!
Drop it all to subsonic territory for organic modulations of morphable voltage.

• Linear through-zero & traditional FM with AC & DC coupled functionality
• Internal modulation routing and general-purpose CV input with attenuator
• Split sawtooth morphing and nonlinear wavefolding
• Precision soft sync
• Directional hard sync
• Individual waveform outputs
• LFO mode"

"Happy holidays everyone!

2020 has sucked on many levels… but hopefully this might lighten some lockdowns:
Instruo is now on VCV Rack for anyone to use for free!
It’s been a busy year but I’ve had the great fortune of welcoming a few new team members to the Instruo crew.
This in particular has been a project that really grew exponentially since June!
With the pandemic still on going, hopefully this will ease some boredom and help inspire some creativity.

Thank you everyone that has supported Instruo to date.
I have many exciting things in development and we thought this would be a nice way to give something back in thanks.

Happy Christmas and New Year when it comes.
And of course happy patching!
Cheers
Jason"

Instruō - Saïch Oscillator

Instruō

See the dealers on the right for availibility.

"The Instruō saïch is a quad oscillator with super-saw functionality and built in “smart” VCA mixing. At its core are four fully analogue sawtooth waveforms that can be intervallically offset, individually and globally detuned, transformed and transposed, and mixed together in creative and interesting ways.

A perfect companion for the harmonàig quantiser, it can easily create harmonically structured chord voicings perfect for lush subtractive patching. Paraphonic patching in analogue with eurorack has now become considerably more convenient!

No quad quantiser in your system? Not to worry!
saïch includes beautifully simple diatonic modes allowing for the creation of
Ionian and Aeolian chord scales with a single 1V/octave CV source."

Instruo Tain // dual bidirectional switch // Eurorack demo & patch tips

DivKidVideo

"Here’s the new dual bidirectional analogue switch ‘tain’ from Instruo. It works as a 2 to 1 or 1 to 2 input or output switcher. It has manual of CV/gate control with latching or momentary behaviour and a handy trick up it’s sleeve is the inbuilt reference voltage. Allowing you to use a trimmer to set a normalised voltage from -10 to +10 volts so you can switch to a voltage as a divider, or sub audio generator, switch from modulation to a static voltage, create octave jumps and more. As always I make these videos educational and packed full of synthesis tips and patch ideas so try these patches and ideas out on your system. I’d love to hear of any variations you’ve been creating with switches in the comments."

"The Instruō tàin is a two channel analogue bidirectional switch, similar to those found on classic semi-modular systems of the 1970s.

With momentary and latching functionality, external control and a manual button per channel, tàin can seamlessly switch between control voltage contours, trigger/gate patterns as well as audio signals all the way into audio rate.

tàin | verb (close) to block up, to move so as to cover an opening, bring two parts together, to make continuous as in a circuit."

Instruo Lion (matrix mixer) // Pin style patching in Eurorack with inserts, sum, attenuation + more

DivKidVideo

"Here’s the new Lion (pronounced Leon) from Instruo. It’s a TRS 6x6 pin style matrix for not only routing and mixing inputs to outputs but as the patch bay uses TRS sockets we can also use Y cables as inserts as well. This allows for easy routing of processors and FX along with making feedback loops, using inverters to build MID / SIDE matrixes from stereo sources, we can also passively split signals with normal patch cables, both attenuate and amplify and a whole lot more. It’s DC coupled at the inputs and outputs so it’s good for either audio or CV and it comes with the pin style TRS cables and a pair of insert cables too."

"The Instruō lìon is a 6×6 matrix mixer with a pin style interface similar to those found on iconic modular synthesizers of the 1970s. Its applications range from signal routing and effect insert functionality to true summing with cascaded attenuation capabilities.

Live patching made easy with the use of the included pin and
insert cables.

Need to patch to a new destination? Simply pin your patch on the fly.

Centralise your I/O network with lìon.

lìon | noun (networking) an open-meshed form, twisted, knotted or woven together at regular intervals, a group of communication stations operating under unified control."

Instruo - Tš-L Overview

Instruō

"The Tš-L is back in stock with a couple of extra bonus features!

The Tš-L is a fully analogue voltage controlled oscillator with a plethora of features in a very small footprint.

Its triangle core circuitry allows for extremely consistent waveforms over a wide frequency range. The triangle foundation is used to generate its sine waveform which holds consistent shape and amplitude across the Tš-L’s wide range. The outputs consist of simultaneous Square/Sub, Triangle, and Sine waveforms, with additional voltage controllable wavefolder and complex PWM waveshaper.

Tš-L includes every feature needed to powerfully perform as a rich, ultra compact audio source, as well as functioning equally as a versatile modulation source."
