Instruō - àradh Overview

Here is the àradh.
tràigh again!
By popular demand - an exciting new take on the legendary transistor ladder filter. Introducing the Instruō àradh, the long-awaited successor to the first Instruō low pass filter, tràigh. Expanding on tràigh’s classic functionality, àradh adds a VCA with pre or post-filter routing options, an envelope follower, a comparator gate, a strike input with variable decay time, and a plethora of user-definable voltage-controlled parameter combinations.
Whether you’re looking for voltage-controlled resonance, pre-gain filter saturation, noise gate functionality, dynamics processing, or even an envelope follower, àradh can get the job done - a true sound-shaping powerhouse in only 6 HP.
• Low pass filter and VCA
• VCA pre/post-filter routing options
• Strike input and button
• User-defined CV input
• Envelope follower and comparator functionality
• Self-oscillating resonance

This is like a trip to the candy store

Man o’ man, is this a tasty filter. 😌 Love the trend of implementing vca’s into everything.

[@nocomment000]

33:49 is a stellar example of how to use filter resonance to pick out harmonics.

[@maxmaleo581]

such an amazing piece of gear ! brillant !

[@vinylarchaeologist]

Thank you for choosing a beautiful sound while demo‘ing the module ❤

[@instruo]

Glad you like it!! :D I always start with a patching session to try and find some musical-ish examples to then build the demos around.

[@colorgasm]

Oof! these chords are so tasty. Now im ordering a Saich, Aradg and cnoc but i also need a Carn

[@instruo]

The aradh completes my go to harmonic patching voice! Harmonàig controlling Saïch into àradh with some envelopes in the mix ☺️

dear jason, just for interest… i‘m building a medium big pure instruo rack at the moment because i love ur modules sooo much. like the sound , the design, etc.… just for me wanting to know, do u think about building a drum maschine kind of module one day??is this a thing for u??

[@instruo]

Maybe one day :) For now a cnōc, I-ō47 and tanh[3] is what I use for pretty much any percussion voice I could need. A dedicated kick module, for example, would very much be a more restricted curation of that circuitry. …but I patch that so regularly it would save me time and HP if it were curated. There are various things on my list! 😁

I'm very curious how you're getting your delay / reverb effect with the Lubadh. Care to share more details on that? What mode/preset is the Lubadh in? There's a few frames at @4:49 that shows the patch but some important cables are off screen so hard to tell what exactly is going on.

[@instruo]

The Lubadh is running the V2 firmware and has the “tape looper” preset applied to each deck. I have short asynchronous loop lengths per deck. I just ball-parked the initial recording takes which defines the “tape loop” length. The delay time can then be fine tuned between length and speed. Then each deck is just set to record continually. The DUB level parameters can define the sound on sound recording per deck. When constantly recording this behaves as a feedback control. (I can’t recall if this is implemented or not in this instance, but it can allow for each deck to function individually as self contained tape delays) The source audio is going into both inputs in parallel. I’m then manually patching feedback from the AUX out to the AUX in via an aradh. Filtering the feedback softens it and helps minimise it “running away” into danger territory! The feedback signal in this context is a mono sum of both delay lines so it becomes a vague ping pong delay but with common content. The Lubadh was developed as a looper, but the new V2 engine is an entirely new animal. It’s a tape emulating delay effect platform that can loop and dub, run multi tap with independence of record and playback mechanisms with polyphonic capabilities!

@@instruo Thanks for the extensive reply!! Love the Lubadh v2 firmware. Would love more of your Instruoctional patch break downs - even of more "simple" patches like the one you describe here. (At least simple compared to your insane (-ly good) patches in the instruoctional series). Love the pingpong effect. Smart way to use the AUX I/O's as a send/receive. Will try it out. Thanks again for the clear description!

[@stefanfountain1909]

@@instruo After rewatching the whole video again -- I see you explain this quite well at around @47:50 or so. Thanks for the extra explanation above. Sorry for not catching the walk through in the actual video. :-)

[@instruo]

@@stefanfountain1909 happy to help ☺️

[@aster_nova]

Is there any chance of getting it added to VCV Rack? (Or is it like compatible with the tràigh in part?) Wondering because I was hoping to try out this patch -> kzbin.info/www/bejne/m6CzaWOJd5tqpqs It's ok if it won't be added -- I don't mean to exert any pressure :) While I'm here I should say that your modules are some of the most utterly beautiful I've seen. Just such a keen eye.
