Instruō - øchd Expander DIY tutorial && VCV Rack update

video upload by Instruō

"Hello!
Happy end of 2024 :)
I hope you've had a good year.

I would like to thank everyone that has supported Instruō this past year and previous years. The company has grown a lot since I was pottering about in my spare room.
I have the pleasure of working along side an incredible team.
A lot of the work these past few years has been very much behind the scenes.
2025 is going to be exciting! I'll leave it at that!

This is a video I've been meaning to do for a while. Since we launched the øchd expander.
The expander module itself was a really fun challenge. I wanted to utilise what the øchd generates in as efficient a way as possible to expand its utility.
Much of the theory behind it I prototyped in VCV rack. Especially the DAC section.
This is a full real time step by step of how to DIY the signal processes and outputs of the øchd expander.
There may be more efficient ways of achieving these and many modules out there provide the same utilities, but this is a collection of patches that I reach for then I need such things.

It's a bit technical, but I hope the video introduces some ideas for patches.
Thanks for watching!

"Here's a smart use of 4HP with clock generation and modulation/processing from Instruo with the new GLOC! Gloc (translates to clock from Scots Gaelic) has a smart tap tempo following clocking system built in for internal or external clocking and then provides multiplications and divisions with can be spread in time and then carved into with two types of probability control. One your typical random/coin toss with variable weightings or smart musical density masks that provide more repetitive musical rhythms. You can also program and lock output states (very simply I should add) so you can go wild modulating rhythms while keeping others constant ... there's a lot going on in an easy to use, small package."

Update: DivKid video added below.

"Hello!
Jason here.
Thank you for watching this video :)

This Signature Edition limited re-release of the tràigh low-pass filter module is available for purchase direct from Etsy:
https://www.etsy.com/uk/listing/18233...

I am producing a limited batch which will be available for purchase while stock lasts.

This revised module was developed as a creative side project over the past month or two as a means of dealing with the unfortunate situation of having a very large pet greyhound with a relatively large diagnosis of cancer.
Winston was confirmed to have a stage 2 soft cell sarcoma earlier this year. He underwent a surgery on September 24th during which the tumour was successfully removed. (He has recovered very well and quickly!)
Due to the location of the sarcoma there is a high likelihood of cancer cells remaining at a microscopic level. If left unchecked they will likely return as a tumour with a chance of metastasising.
Winston began a 4 week treatment of radiotherapy on November 4th.
As of writing this we are now past the half way point and he is responding very well with no significant side effects presenting.
Each treatment requires full general anaesthetic, so I have a very dopey boy every Monday, Wednesday and Friday for the entire month of November.
The vets do provide him with some roast chicken each session when he wakes up. So he seems quite happy with his current unusual routine.

"The Instruō cèis[2] is a fully analogue voltage controlled ADSR envelope generator. The ADSR function generator is the model pioneered by the East-coast mindset and is extensively used in subtractive synthesis patches. The cèis[2] gives the ability to externally control the attack, decay, sustain, and release stages of the envelope while also emitting trigger and gate signals for each segment, offering maximum versatility from a classic tool.
This version [2] revision brings additional flexibility and control through a completely redesigned logic extraction circuit for the segment gates, envelope re-trigger input, and a precision throughput for voltage controlled slew limiter capabilities.

• LED button for manual control and indication of output CV level
• Fader and CV control over all 4 segments
• Gate output per segment
• Fader LED for segment stage indication
• Gate/Trig modes which can force completion of the Attack duration when triggered
• Hold mode for sustain segment lock for CV slew use
• Combined trigger output which fires when there is a change in segment
• Variable envelope response shape from linear to exponential

Roma Modulare 2024 Synth Event Set for Rome on September 27-28

video upload by Roma Modulare

Press release follows:

Roma Modulare 2024 announced as international synthesizer and music production expo in Italian capital city namesake

ROME, ITALY: organisers of Roma Modulare 2024 — the most important Italian event dedicated to modular and desktop synthesizers plus professional audio production — are proud to announce that it will be being held as a two-day international expo at Forte Trionfale in the centre of Rome on September 27-28…

As an international expo hosted in the capital city to which it, in part, owes its appropriate appellation, Roma Modulare 2024 readily represents the most important Italian music industry diary date for all musicians and audio professionals — particularly those who are passionate about modular synthesizers, as also alluded to by name. Notable headliners amongst its 80-plus exhibitors include German electronic musical instrument manufacturer Doepfer — duly credited with creating the Eurorack small-format modular system around which its ever- expanding A-100 ANALOG MODULAR SYSTEM is based, subsequently swelling to industry-standard status with hundreds of third-party manufacturers making compatible modules; Latvian Eurorack modules and desktop instruments creator Erica Synths — showcasing the intuitive nature of its PĒRKONS HD-01 desktop drum synth and aggressive timbres of its Black series Eurorack modules; hand-built Scottish Eurorack module-maker Instruō — instigating eye-catching aesthetics with the likes of its arbhar Granular Audio Processor and Lúbadh Dual Looper modules; American musical instruments and Eurorack solutions provider TipTop Audio — advancing production of Don Buchla’s trailblazing 200 series and converting it to Eurorack standards as the 200t series project; Mark Verbos-designed, Berlin-assembled Eurorack format synthesizer module specialist Verbos Electronics — whose Harmonic Oscillator module is now available in Eurorack for the first time; and American Eurorack modular synthesizers and guitar pedals producer WMD — back in business and announcing a new drum module; and many more.

The two-day international expo will be held in Rome’s Trionfale district within Forte Trionfale, one of 15 forts surrounding the eternal city. Built between 1882 and 1886 in an area covering 21 hectares, the military complex was famed for Italian aviator, aeronautical engineer, and Arctic explorer Umberto Nobile’s airship departing for the North Pole from one of the fort’s hangers in 1926. Today the location is part of an urban regeneration program, aiming to enhance creativity and create connections between people, an admirable objective that is not lost on Roma Modulare 2024’s organisers. “Our greatest desire is that Roma Modulare provides the best opportunity possible for musicians, producers, technicians, manufacturers, and even amateurs to come into contact with each other to strengthen the Italian music market and make it international,” announces Alberto Rossetto, Founder & CEO of Rome’s Milk Audio Store — specialising in Eurorack modules and studio equipment — which has partnered with K-ARRAY Audio Solutions — founded in Italy as one of the most innovative high-technology professional speaker manufacturers in the world — and Doc Servizi — an important cooperative created by a group of musicians to help navigate the challenging entertainment sector in Italy — to organise Roma Modulare 2024.

Although a 900 m2 area within Forte Trionfale will be dedicated to hosting Roma Modulare 2024’s 80-plus exhibitor booths, part of the venue will be dedicated to creating a Workshop Area, where, over two days, 20 speakers will take turns in presenting new products or exploring topics relating to the entertainment industry (with the full program listed here). But, by its very nature, Roma Modulare 2024 is also about the assemblage of and meeting with electronic music artists. As such, a Live Area will be opened up in the garden outside the venue between 1:00 pm to 11.30 pm each day, where electronic music artists will effectively play a non-stop live performance with their modular synthesizers. It is fair to say, then, that Roma Modulare 2024 promises to be an exciting event for all attendees, Italian or otherwise, and all appetites will, quite literally, be catered for with on-site food and beverages being served from opening (10:00 am) to closing (midnight).

Tickets to Roma Modulare 2024 are available to purchase as a two-day pass — priced at €22.00 EUR — or as one-day tickets for either September 27 or September 28 entry — each priced at €13.50 EUR — directly from here: https://www.romamodulare.it/tickets/ (All tickets include entry to the expo itself and an evening party, while entry is free for under 16s.)

cruïnn - Stereo Super Saw

video upload by Instruō

"Exploring sound examples from a stereo super saw synth voice using the cruïnn.

The sequencer or keyboard sends voltages to cruïnn while simultaneously triggering the envelope generator. The CV output of the envelope generator opens two VCAs, allowing cruïnn to pass through. Two LFOs modulate the cutoff frequencies of two filters, creating a stereo modulation. Depth and Rate parameters are increased to apply phase modulation."

Folded PWM Tš-L

video upload by Instruō

"In this video, we explore some sound examples from a folded PWM synth voice using the Tš-L as the primary audio source.

Connecting the PWM Output to the Wavefold CV Input allows for four levels of timbre control via the PWM knob/PWM CV Input, the PWM Waveform Crossfade knob, the Wavefold knob, and the Symmetry Bias knob. The sequencer or keyboard sends voltages to Tš-L while simultaneously triggering the envelope generator. The CV output of the envelope generator opens the filter and VCA, allowing Tš-L’s signal to pass through. More traditional East Coast patches would incorporate separate envelope generators for the filter and VCA."

Quantizing with Dàil from Instruo

video upload by NOISEBUG

https://www.noisebug.net

"The Instruō dàil is a high resolution quantiser, precision adder, MIDI-to-CV interface, and USB MIDI Host with a very small form factor suitable for any system.

As a quantiser, scales can be defined locally as well as externally via MIDI. The USB Host port will accept and power class compliant devices offering convenience and immediacy to melodies and sequences.

As a precision adder, existing signals can be offset by any defined chromatic interval. Transpose anything with accuracy using the calibrated buffered throughput which runs parallel to the quantiser engine. This feature alone makes for a great companion to any sequencer or 1V/octave source within a system.

No longer is a single repeating octave of quantised notes a limitation. dàil features a fully bipolar quantiser engine through which any multi-octave spanning scale/chord/arpeggio can be engaged immediately from your MIDI keyboard. Patterns can also be programmed onboard with precision with the ability to auto fill from a wide range of major and minor starting points.

Small form factor, big feature set!

Instruō Introduces dåpf Dual All-Pass Filter Effects Processor Eurorack Module

via Instruō

"Introducing dåpf, the first dedicated effects processor in the Instruō product line. The Instruō dåpf is a set of two analogue all-pass filters.

You might be asking yourself, “What is the point of a filter that passes everything?” All-pass filters don’t actually attenuate frequency amplitudes directly, but rather alter the phase relationship of frequencies across the spectrum. All-pass filter stages appear in the vast majority of voltage-controlled filter topologies as well as serving as a core building block within DSP.

The normalled I/O of dåpf allows for cascaded or independent use of the two all-pass filter circuits, offering everything from classic phase-shifting to psychoacoustic stereo enhancement and synthetic Doppler effect.

• Two parallel all-pass filters
• Independent attenuverters for voltage control
• 1-Pole/2-Pole configuration for left channel
• Cascaded normalisation
• Global 1 volt per octave tracking"

Wow! I didn't know All Pass Filters could do this // 3 Patches with dapf from Instruo
video upload by DivKid

"I'm always striving to learn and explore with sound and music and dapf (the new Eurorack module from Instruo) certainly brought a big slap of school day into DivKid HQ. I was aware of all pass filters, getting past the funny idea that "all" frequencies pass (so what's the point?) and knowing they were use for phase shifts. What I didn't know is how core and important to filter topologies they were and how creatively useful they could be.

Some exploring later and here we are, with 3 patches that really show the power of phase manipulation. While dapf makes a fantastically chewy phaser FX unit I didn't expect it would be such a great stereo expander for a single VCO nor did I know I could be MUSICAL and totally analogue 3 operator FM/PM (like the digital Yamaha DX and Casio CZ phase/FM methods) synth."

Granular Guitar

video upload by Instruō

"làrachd is utilised as an input stage for the guitar.
The output from làrachd is patched to the Onset Input of arbhar.

When an onset signal is detected, arbhar begins recording the guitar. Once the buffer is full, we can use the Spray Knob and Scan Knob to explore which part of the recording we would like to hear.

The guitar signal normals to làrachd's envelope follower.

The Positive Envelope Output of the làrachd is used to modulate arbhars Intensity. As a result, when a loud input signal is present, fewer grains are triggered from the arbhars Continuous Granular Engine.

The Negative Envelope Output is offset using a vincâ and used to duck arbhar's internal reverb as well as adjust the Dry/Wet Mix when an input signal is present.

arbhar’s Pitch Deviation Knob is positioned fully clockwise meaning grains are transposed up and down octaves.

Finally, the left and right outputs of the arbhar are patched to the cuïr, which is used for gain staging and final signal output."

MEET THE NEW OCHD EXPANDER. A 24 OUTPUT MODULATION PAIRING IN ONLY 8HP, NUTS!

video upload by DivKid

"The new ochd expander adds 16 outputs to ochd with 4 sections of different functions. We have unipolar outputs from full wave rectifiers, analogue diode logic giving 2 pairs of MAX/MIN outs, a cascading mixing trigger section for stochastic timings and a 4-bit DAC ladder section offering 4 flavours of slow noise stepped random patterns. It really is a mammoth addition of functions not just to ochd but to any Eurorack system.

The ochd expander was released as part of ØCHD-OBER-FEST an in-person event that was also live streamed. If you’d like to watch the event check that out here"

ØCHD-OBER-FEST (live event) with DivKid, Instruo & Signal Sounds // celebrate all things ochd!

See the dealers on the right for availability.

"Launched in 2019 and designed in collaboration with Ben "DivKid" Wilson, the Instruō øchd has set a standard for compact and versatile modulation sources which can now be seen across thousands of eurorack systems.

The øchd's 8 analogue outputs can now be be tripled with a farther 16 unique control voltage sources by pairing it with the øchd expander ([ø] 4^2).

All outputs are derived from combinations of the 8 analogue triangle LFO cores to produce an extravagant range of variable voltages, triggers and 4x 4-Bit DAC based stepped random voltage sources which are best described as flavours of "slow noise".

Enhance your existing modulation capabilities immediately with this 4HP cluster of control voltage capabilities.

Note: øchd required, all cables included with expander"

Instruō - Befaco FX Boy - microPhaser cartridge | All-pass filter tutorial

video upload by Instruō

"Here's something a bit different!

Befaco (https://www.befaco.org/) have launched this very cool module which uses the "game boy" cartridge form factor as a means of hot swapping analogue and/or digital circuitry as effects processors.

I caught up with Manu and Diego at Superbooth23 and learned of this mad idea. I very quickly asked how I could get involved and contribute a cartridge design.

Time was a bit of a crunch.
I set the target of a month following return from Berlin as a timeframe for getting a cartridge production ready.
Challenge accepted!
I believe I had the first two (heavily circuit bent) prototype cartridges in the mail to Barcelona in just over a fortnight.
The last 5 minutes of this video shows a bit of this process designing the first prototypes.

The FX Boy ships with 7 carts in total designed by a wonderful range of creative developers.
I'm very excited to be part of this project.

This video goes through some of the capabilities of my microPhaser effect and ends with some behind the scenes recordings of the rapid development of the circuitry.

Cheers!

arbhar - Firmware update tutorial


The arbhar V2.0 firmware update is here!
In 2019 the launch of the arbhar heralded 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. Each grain sounds with its defined specifications. When modulation is used, the "per-grain parameter" definition allows for true polyphonic layering.
With the introduction of firmware version 2 (2023) comes a complete rewrite of the entire codebase to implement both technical and conceptual improvements that will enhance the entire user experience of the arbhar. We have ensured that the overall feel of the module has been preserved as much as possible. Advances in efficiency and expanded features will allow the arbhar to explore many more sonic and musical spaces.
Meet the Lexer Method 2.0.
