Instruo Module Overviews & More

Playlist at the time of this post:

1. Instruo - Lubadh Overview
Consisting of two identical channels Lúbadh allows you to instantly record, playback, overdub, trim down, scan through and pitch up or down any audio signal.

Inspired by the aesthetics and mechanics of early tape techniques each channel features an analogue input circuit which adds slight compression, filtering and saturation. On the first recording, the sound may appear slightly fuller and warmer,
re-recording audio back and forth will compound this effect over time allowing you to create dense tape like textures.
2. Instruo - Arbhar Overview
arbhar heralds a new generation of granular processing in eurorack. Sampled audio can be chopped into tiny grains, scattered, shaped, re-pitched, reversed and layered for an endless range of audio manipulation from seamless frozen tones to mutated acousmatic madness.

Featuring a condenser microphone set into the front panel, built in audio analysis for automatic sampling and internal modulation over various parameters; this is truly a granulator like no other.

5. Ceis
Cèis is a fully analogue, CV controllable ADSR envelope generator. The ADSR is a more traditional shapable voltage control voltage envelope used extensively in subtractive synthesis patches. The Cèis allows full voltage control over the 4 segment faders with multiple gate/trigger outputs for maximum versatility of a classic tool.
6. Tanh[3]
triple waveshaper/limiter module.

This 4hp module can be used in many ways. This video demonstrates it applied to the feedback path in a delay.
A percussive tone is played into the delay with varying pitch.
The feedback is patched through a tanh[3] channel and mixed with the direct input of the delay.
As the feedback level approaches, and even passes positive feedback, the tanh limiter restricts the amplitude from increasing past a certain threshold.

This limiting can allow for very stable sustaining echo's/delays/reverb effects.

Also demonstrated in the video are the affects of the tanh waveshaping on classic waveforms.
7. Instruo - Cs-L Overview
Cš-L is a dual voltage controlled oscillator.

It takes the modern approach of dual primary oscillators and expands upon them.

Each oscillator sports its own wavefolder, PWM output and wide range of classic waveforms.

A four-quadrant multiplier stage allows for ring modulation as well as rectified and positive only amplitude modulation.

Each oscillator uses a different core (top sawtooth core, bottom triangle core) giving the best of both worlds.

A versatile, definable routing modulation bus allows for CV control over a huge range of cross modulation without even needing to insert a patch cable.

9. Instruō - The Anatomy Room
Patched and recorded August 2017 on residency developing a piece in the Anatomy Rooms in Aberdeen.
The patch built around a chord progressions generated by the Harmonàig quantizer controlling the pitch of 4 oscillators (troika + tòna).
10. Harmonàig - Polyphonic quantizer overview
The Harmonàig is a polyphonic, diatonic CV quantizer module.
It has a main CV input for quantizer mode which can be scaled and/or inverted with an attenuverter.
The module generates 4 CV outputs. The module works with -10V to +10V CV ranges in and out giving it a potential 20 octaves range.

The CV outputs voltages are designed to control the 1V/octave inputs of 4 independent oscillators.
When the oscillators are all tuned to a unison, the Harmonaig will generate all the note interval CV offsets to automatically tune the 4 voices to 4 part 7th voice chords.

The chord quality is determined by the incoming voltage being quantized. The tonality is defined in musical modes (ionian, dorian, mixolydian etc), but knowledge of modal and music harmony theory isn’t required. Within any musical modal centre, all chords generated for any note will be harmonically relevant to the modal centre.

I designed it to be patchable and intuitive to how most monophonic quantizers work, but with the polyphonic chordal capabilities for creating chord progressions and voicings.

A secondary mode allows the keyboard to be directly performable for selecting chords.
Manual/CV control over the chord quality is also possible with the addition of 4 user definable chord voicings that can be programmed in.

Additional features are a trigger/gate output: triggers are generated in quantizer mode everything a new note is latched to, keyboard mode generates gates when notes are held.
Chord inversions and voicing spread can be controlled via pots and CV for changing the note order and range distribution of the notes.
The CV outputs have their own independent slew limiters which allow for varying amounts of glide between notes, per voice.
There is a fader which has various functions for transposing within the defined scale as well as globally.

This module is something I’ve been developing conceptually for a number of years now and I am very happy with it.
I have performed with prototype version in my own performance setup for a while now. I’m hoping it resonates with other users and creates some exciting music :)
11. Delta Studios - 'u dancin u askin am askin am dancin' Nov 2016
'u dancin u askin am askin am dancin'
is an exhibition of artworks made by the variety of people who attend Delta Studios - The Creative Centre.

Delta's ethos is Art, people, community and you.
A philosophy carried out with vigour and imagination - making Delta unique in Britain.

12. INSTRUō - tràigh [build video 2]
To jump directly to the module demonstration start at 13:05

This is the second module build by Instruō
Tràigh is a transistor ladder based, voltage controllable low-pass filter with a built in 3 channel mixer.

The schematic is derived from various vintage synth schematics that were published with classic maintenance manuals.
Huge thanks to the wonderful people of the synthDIY community who are an endless supply of advice and knowledge.
13. Instruō - 'Unrush' [Modular Synth Patch]
Ambient modular performance by Instruō.

This video was shot during rehearsal and prep for the first Unrush live event which took place on the 3rd November 2016.
The patch opened a live ambient set performed by Post Scriptum & Instruō.
