Instruō - Saïch Overview 

Thx man

Thank you, sir!

Please Instruō you should give some module to Omri as present he his one of the most followed as RU-vid and a big know how in Eurorack and vcv teacher and great mind and soul as artist

Thank you Omri this is the minimum that Instruo should to do also because it is not chip

@@dedodan1 Since YOU are so grateful, why don't YOU buy it for him? ... by the way, why don't you buy my cousin a car, he really needs it, he's a good guy too, I think it's the minimum you should do...

agree- Instruo, Folktek and Frap Tools are the most attractive looking and sound modules today in Eurorack world. Amazing artwork, aesthetics and tones.

@@GuitarsAndSynths id put Joranalogue up there too, though not quite as stylin appearance wise

And unreasonably precise

@@index7787 huh? meaning it's very precise?

Just realised I'm only 15 minutes into an hour and three quarters 😂

I like to be thorough in my videos 😉

That’s a really great discovery! I’ve used this exact trick for years to demonstrate phasing and beat frequencies, but never thought to use it specifically as a visual tuning aid! Definitely the first instance I’m hearing of the Lubadh being used as a single point strobe tuner. 😂 Thanks you for sharing, and I’m very happy to hear you’re enjoying the module ☺️ Happy patching!

Been really thinking about this. Would be amazing to have separate outs, possibly switchable between pre and post VCA. That or a stereo out with either a pan knob for each VCO or preset algorithms assigning location within stereo field. Dedicated sub out would be very useful as well for separate filtering and processing.

I'm really new to modular, but it seems to me like if you had separate VCO audio outs, you could patch this with a 4-channel MIDI interface and something like the Doepfer A-141-4 for uniform VC envelope generation across all four gates, and that would give you really compact 4-voice MIDI polyphony in Eurorack. Maybe not as novel as what this can do with the harmonàig but still interesting to think about

@@lunasspecto Sure, a MIDI-to-CV able to parse polyphony into separate CV outs could already do what you describe with Saïch, but it would still only be a single mono out with all voices sounding unless you use the internal VCAs to fade between them. So not really capable of a single voice at a time without work arounds. Ideally, multiple VCOs detuned and spread by pan creates a very full sound. Acid Rain Chainsaw, for example, creates a great wide supersaw/square in stereo using 3 voices each made up of 7 VCOs spread in stereo, 4ms Ensemble Oscillator and Xaoc Odessa can do the same by separating odd/even harmonics to left/right outs, with Ensemble Oscillator being technically only a single voice as far as input CV and Odessa up to 5 voices with Hel expander. Just seems a missed opportunity not to have some stereo options with Saïch. It is incredibly complex as it is and analog, whereas the other stereo VCO I mentioned are digital, so maybe not really possible.

@@precarious333music Yeah, I figured to do what I described with separate VCO outs but no individual VCA CV inputs, you'd need an external VCA… but by that point we're not really taking advantage of the saïch's features. I've been trying the virtual saïch and harmonàig in VCV Rack, and there, because it's virtual, I can just clone the saïch, feed the same harmonàig CVs into into both of them, and feed their mixes into a stereo pan. If only it were that easy with hardware! 😅

@@lunasspecto True enough. You solved the dilemma. Just buy two Saïch!

🤣

Thanks! :D I'm trying to keep a strong educational element to my videos. They do run a little long... but being in lockdown is a good excuse for that! I'll actually be doing another sit down livestream/podcast with Ben/DivKid on the 15th (I believe that is the planned date). Long form Q&A. I'm planning to have a system set up that I can switch view to for doing some demos etc. If you can tune in live, we'd be happy to have you asking exactly those type of questions :) Cheers! Jason

@@instruo Thanks Jason. I hope I will be able to tune in on your livestream. Yes your videos are long but I tend to take them in portions as my head has to digest the info and for some reason tends to wander of on question quests. Also your demos are invaluable when I finally buy one of your modules. Like I don't know how many times I've watched your Harmonaig video after I bought it. Have a good time and stay safe. Jonas

It pairs with Sinfonion‘s chord output just as well as with Harmonaig. I guess running Sinfonions mono channels into this is a bit restrictive as Saïch only has one output. Interesting effects can probably be achieved, though, with the different profiles.

Development has been long on this one. Many iterations over the years and many things learned from prototypes and my previous oscillator designs. I have actually included an expander breakout header on the back of the Saïch to keep my options open! Mixing between different waveforms is of course a very powerful tool, but in practice maintaining a more consistently musical equal loudness, and balance between the layered voices becomes less simple. The overtone content of sawtooth and square waves are very similar. Mixing in triangles and sines become much less prominent without changing the mix and increasing their gain (all this dependent on frequency range and context of course). When adding single sine waves in particular to a mix of saw/square. Only a single harmonic is being added to a wider spread of harmonics, which doesn't add much. I use the saïch most often as a rich subtractive synthesis sound source. Either in parallel unisons, perfect intervals or paraphonically harmonised form the Harmonàig. To produce the other waveforms from a sawtooth core takes quite a bit of circuitry, and requires additional calibration for the accuracy I like to maintain. Adding such waveshaping and parallel unmixed outputs would have increased the design's HP considerably, as well as the costs. And at the end of it I would have ended up with the troika again but with less independent control per voice. With all that said, I am certainly not writing off the possibility of an expander for the saïch by any means! But to meet the obvious features of independent outputs offering more waveforms it would be big and waaaay too expensive. Especially when the troika already exists! I will be keeping eyes and ears open to all feedback as the saïch gets out there into people's systems! So please do let me know what you think :) Cheers! Jason

@@instruo This reply is way too good for the youtube comment section. My initial thought watching this is I would love to not have to tune 4 oscillators before patching even starts. Your module addresses so many of my pet peeves before it ever makes a sound and simultaneously streamlines common stacked intervals. And you are right, for a rich harmonic waveform the saw is the king (especially in analog), the pulse wave is queen, and everything else is too delicate to be heard in a stack of saws and squares. But... I just keep thinking about how you could apply this interface to 4 operator FM. Especially the macro crossfader which already seems to have a bank of useful ratios that I use in FM algorithms. If I were to design your expander kit I would add individual sawtooth outs, fm inputs with trim pots, and hard sync. I would have all sorts of fun self patching those parameters.

Thanks! :D The Sheikah module is my sample&hold and noise source which I styled in tribute to the Legend of Zelda. Only that one and 2 others exist (my own personal one and two others were gifts).

@@instruo - thanks for the reply! Whilst I am (selfishly) a tiny bit sad there are only 3 in existence I believe this fact also makes this module all the more special!

@@instruo Bummer, I had the same question. Couldn't see a label on it even after I zoomed in. Very cool looking module. Do you plan on making any of those? You should, I think people would purchase it. Including me, LOL!

as someone who works with alternative tunings, if i was to someday pick up a saïch, being able to edit the offsets to ones in a tuning i was working in would be really handy

Yes! And imagine four outputs!

They’re all Instruō ;) www.signalsounds.com/instruo-eurorack-patch-cable-30cm-5-pack

@@instruo Thanks! I will definitely order some when I get a few of your amazing modules. I just need a larger case :-)

No plans. I utilise the transparent nature of the FR4 material as part of many of my designs for backlighting purposes. …but if we follow the science from Star Trek IV, there is only ~110 years to wait until the invention of transparent aluminium! So there still is hope for a viable solution :)

i believe its a one-off , with anything Instruo need on the fly -

It’s my sample & hold and noise source. A one-off tribute to Legend of Zelda 🤓

@@instruo I would love for you folks to do a deep noise module a la ERD All the Colours of the Noise but with the Instruo flair - more noise==more better. Thanks for all the great work (and yes, I love the look of that one-off).

and trippy as fuck @ 1:20:25

Please give us an answer … or an led faceplate 😅👍

That's answered in earlier comments. (It's a one-off S&H and noise generator.)

@@bmbiz Thats a shame, it is really cool looking.

Today :) The first batch was completed a couple of weeks ago so then could get out to retailers in time for today’s launch. (Freight delays dependent of course) But they should be popping up in stores now!

They are official Instruo cables :) I have a new run of them on order! www.signalsounds.com/instruo-eurorack-patch-cable-60cm-5-pack

In one of DivKid's livestreams Jason said they have things in the works and to stay tuned. So I would guess eventually, yes!

Eventually, yes :)

@@instruolooking forwards to it

Agreed!!! I’ve gotten a lot more practice, and I’m no longer shooting from my phone 😬

Dude I’m working on it! 😉 This is an older video! I’m always trying to improve on what I do. Harmonàig does pair very nicely with the Saïch. Almost like they were made for each other 😊 Thanks for watching!

@@instruo don’t worry i wasn’t being critical. Thanks for the fast response. I know you do so much work mate, don’t worry. Keep making amazing modules - I have a lot of your stuff already. Just struggled to figure out when the button is on, thats all:)

@@earlsfield I just watched back a bit of this video and the lighting is not good! 😂 This was shot in my living room on an old lumix camera with the AWB engaged. The new videos are shot in the workshops dedicated video studio now with some substantial camera upgrades! I went full nerd during covid on video cameras and lenses!

@@instruo lol dont worry mate, I know this is an old one. I can imagine lockdown giving you extra time to geek over tech, I mean, I doubled my synthesizer intake lol. Yeah new videos are better produced, better camera and sound, you are going full on Ridley Scott lol. Thing is, while I can appreciate the fact that of course, the most important part of your work is creating inspiring, amazing modules - which you do - videos and tutorials are also super important. Took me a minute to realize why the offset doesn't work (without detune being moved from 0 and vice versa) - although it is well explained in the manual, with full time job and all there is just so much time you can dedicate to learning curve and videos are the best way. I would be happy to do a few videos with Instruo the gear that I have, no charge or anything. BTW, riddle me this - I always considered Instruo to have probably the best design (visual, aesthetics) out of all modular stuff out there. Was H.R. Giger an inspiration, at least partially? You don't have to answer if this steps too deep into your IP, I am just curious:)

It’s binary :) 001 - 1 010 - 2 011 - 3 100 - 4 101 - 5 110 - 6 111 - 7 MSB - LSB order: (‘’’) (‘’) (‘) What you describe could have worked as well of course, but I figured base 2 binary counting is already a well situated standard and very easy to write in code

At that time code and particular example there will always be a degree of constant drone. The “amplitude” enveloping is done by the envelope over filter cutoff of the low-pass filter. But between envelope spikes there is still a level of lower frequency content pass through. It will all be dependent on your fundamental pitch, fundamental filter cutoff frequency and depth of FM over the cutoff. To achieve silence between notes add a VCA into the audio signal path. This could be pre or post filter. (I prefer going post)

@@instruo wow talk about instant and concise response thank you so much! Love your modules, and having them in VCV is a great to test drive

@@instruo Thank you, I was better able to follow along in VCV, what a beautiful group of modules, genius idea to provide software versions for free, it's really making me consider a purchase..

I'll never stop!!!! :D
