Author **VIDEO** RYO Optodist Overview
ben_hex
So here's my latest module overview video. Had some real fun with the Optodist it's a really great unit. I've crammed a lot in again and hopefully as with the other videos so far you'll all appreciate the longer length and more in depth coverage. It covers basic overview and features, acid patches, crunches up FX sends, mangling drum hits, drum loop distortion and envelope modulation, clipping CVs with the LED limiting and more.

As always I invite everyone to follow my general video thread to keep up to date with all videos but for now here's the Optodist! w00t

From the video description -

Here's my overview video for the RYO Optodist, voltage controlled distortion and saturating VCA. It passes both audio and CV so you can clip and modulate your control voltages as well as audio.

For more information head to the companies website here -

As always any questions ask in the comments or message me. Like the video and subscribe for more coming soon.

If there's anything you'd like to see from my set up let me know and I'll try and get a video together.

Nice work, the distorted beats around 13:30 are great. I never even built my kit, maybe I should give it another chance.

Awesome video Ben..

Super stuff

theewiper
Yes, awesome drum sounds. Excellent demonstration.
Ras Thavas
Thanks Ben, great video! The Optodist seems to have a sweet sound that moves into a pretty huge & warm distortion, I like it.
JRock
Awesome Vid thumbs up
Cool Sounds:)

Optodist is a great lil module, nothing but praise for it from me
truckasaurus
Well done! Thanks for such a comprehensive look at this module. I've been really curious about this one and your vid was super helpful. BTW, is it a relatively easy build?
Ginko
Great video! The best bit for me was the very end, I hadn't thought about running CV through the optodist - and then wave shaping with modulation is a brilliant idea! Thanks! thumbs up

Here is a tip for everyone: for a jaw dropping, third eye prying distortion sound from the optodist, try running sounds through a spring reverb before the distortion. This adds a really tactile dynamic to the sound and a trailing body of noise with lots of harmonic action. You cant keep this idea though because it is like my signature sound right now hihi
Ginko
Sweet, so this morning I tried going sinewave into spring reverb into optodist - sending CV pings into the optodist - sounds amazing! somewhere between a thumb piano and a steel drum w00t
drip.feed
One of the best how-to videos I have ever seen, and also a great showcase of why a modular is a different kind of instrument than a conventional synthesizer.

I hate distortion in patches and drums. But even I own an Optodist.

Without wanting to change topic - did you get anywhere with your LPG in the end drip.feed?

It's on hold for now Ginko. The module outputs 4 separate signals just fine and I am unlikely to use the Mix output anyway because it doesn't allow control over the individual volume of each LPG, so it will be a long time before I summon up the will to debug it (probably right before I sell it, to be honest!). Did you ever publish the mods you made for 'the perfect' frequency control?
Tripadvizer
Thanks for the Video! now i want a optodist
wetterberg
fantastic to see RYO get some love. I love my optodist, and I find myself thinking of excuses to get a second, hehe.

Great demo, btw. I think detuned saws going into the optodist is the most brilliant thing, so I'm glad to see that featured as well!

Rockin' Banana! thumbs up

Haha, I did post up the resistor changes I made, every time I do something like that though (as in publish my mods) it usually turns out that I have made a mistake somewhere else... I am a great source of misinformation hihi
MindSnared
Amazing video love Loving the work you've done with the Optodist, great sounds and pacing, lots of useful patch examples thumbs up your back catalogue is impressive and great advice on what's out there as well and I very much look forward to seeing more awesome synthvids from you, cheers w00t SlayerBadger!
Stollmeister
Great video! Keep them comming!


Also, the Optodist looks great.
matttech
Yeah, i am liking my optodist thus far. Nice vactrol vibe to it.

i am sure that last time i used it it wasn't closing completely as a vca. Maybe it is not meant to actually do this - is everybody else's the same? (ie: not closing completely when used as a clean-ish vca)
ben_hex
sempervirent thanks mate, yeah definitely get the kit going. Great unit. I've been finding myself just sending patches through it for some warmth at low gains (and lower signal level which I missed in the video) or driving pre filter oscillator mixes or post filter so it grabs and pushes resonance nicely.

sixteen theewiper Ras Thavas JRock phono1337 cheers guys thumbs up

truckasaurus I didn't build it, got direct from RYO assembled so I can comment on that. DIY friends say it looks simple and it's documented as such so I'd imagine so. Maybe not for me though I'm DIY useless! Haha.

Ginko definitely gets nasty after spring reverb :-) good idea. Think I need a new bigger tank for my A-199 to get some different tones. The thumb piano idea is great. So good in fact I've filmed my second "patch ideas" video on it. I'll credit you throughout for the idea. Definitely heard some thumb piano sounds in there while trying it out.

Cool Sounds! My next module.. It's peanut butter jelly time!

Glad you like the module! smile

There is some bleed through when fully closed, SR3 vactrols/optocouplers have noticeably less bleed than SR2. All the vendors have SR3 as it is a more popular choice. This video is also made with SR3 vactrol Optodist.

One thing you can do to make it close more is replacing resistor R9 68K with a lower value for example 10K. It will reduce the bleed significantly but also lessen the distortion effect.

Another thing is tweaking the trimmer to lower max gain, it would also reduce the bleed a little.

Replied to the first page earlier and now second ...

drip.feed wetterberg MindSnared cheers guys, defi itely more coming soon.

matttech, I did have a little bit last night actually. Could just hear a muffled sort of tone creeping through. Was fine as it wasn't the final vca in the patch.
bodo
Great demo, great sounds, really nice flavor of distortion (which in general, I'm not too fond of, like some others stated).
ben_hex
cheers bodo it's really versatile. I'm using it loads for anything from subtle bit of colour of an oscillator right at the start of the patch to heavy distortion and clipping at the end of a patch. Having fun clipping LFOs through it, especially the E350 and mixes of the uLFO outputs.

Yes great video, i purchased a optodist kit after watching thumbs up

nice one, glad to see you've picked one up.
FatRocky
After watching that excellent video demo , I want to build two Optodist (complete kits) Where can i find them? I'm in South America so either US or UK is fine for me.
Thanks thumbs up
ben_hex
Cheers FatRocky thumbs up

For the US I know synth cube had so,e. but a quick look shows them out of stock. You can get a full kit or PCB/panel from Thonk here - http://www.thonk.co.uk/shop/ryo-optodist/
FatRocky
i placed my order from Thonk
can't wait to get them
Thanks
Guinness ftw!
Ginko
It doesn't look like they sell them directly from the Ljunggrenaudio website anymore - Thonk and Synthcube both stock kits along with some other Eurorack webstores that sell both kits and assembled modules

EDIT: woops I was a little late there...

Thonk.co.uk are selling them at the moment

Blimey by the time I typed the above there were 3 replys lol
ben_hex
Yeah went a bit mental as we all went for that one at once. I know that RYO don't have stock at the moment so not available through their webstore at the moment. I imagine they'll re-stock soon though, but don't have any information to base that on.

For anyone that didn't see Ginko's suggesting for making a thumb piano style sound, check that out if you have spring reverb and an Optodist. Great idea, I'll have a video on it in a couple of weeks. The module overviews have taken over for now though thumbs up

RYO did say something along the lines of "we will close our webstore once we feel satisfied that vendors have significant stock to distribute our products" - they don't seem to have a store at the moment so perhaps this has happened?
MindSnared
Thanks for all your kind words about the Optodist and the cool patch examples, keep the ideas flowing guys smile

Yes, as Ginko says the webshop is retired in favor for vendor distribution, so far we ship to these vendors.

Is Synthcube getting a restock soon?

As far as we know we are excpecting a new order from them soon.

Sorry for mis-information with my ideas. I do remember the closing of the web shop now. Thonk has them in though smile

I just built it, and it was my first bit of DIY (other than soldering together a few cables, jacks and passive attenuators). It's quite a densely populated PCB, so it requires some precision and patience. I'm afraid I rushed it, got the 2 transistors in the wrong places despite the very clear instructions, and fried one. Luckily, RYO included 2 of each transistor, so I was able to fix it all without trying to find replacements thumbs up

Overall, though, if you're not a complete doofus like me, it's a relatively easy build with an excellent step-by-step build manual.
ben_hex
Glad to hear it worked out alright, two of each transistor is a good move from RYO.
EarlJemmings
Yeah, I found it a super easy kit. One extra of pretty much everything not too expensive.
Unfortunately guests came in as I was installing the last vactrol, and I put it in backwards d'oh!
Luckily reversing polarity doesn't seem to damage them, so it's all good.
One thing I want to try though, is putting in poor man's vactrols a la noise swash - led pointed at a photoresistor. Fell like that would be fun w00t
Mefistophelees
I built one of these a few weeks back. I haven't done any electronics in a long long time so I'm glad it was so easy to build.

As a module it sounds absolutely great. Really nice tone.

Yeah certainly is pre filter, post filter, just on a triangle wave before other waves into a mixer, output, drums through it. Love it! Ginko has a great idea with spring reverb and a short triggers into the Optodist creating a thumb piano style sound. I've got a video filmed for that but no voice over (just notes) or editing done yet. Got pushed back a bit with other videos coming through first.

That would be good, making a couple of up with different flavours would be cool. The LEDs changed out affect the limiter circuit too if I remember right.
matttech
I got some amazing sounds by running the output of a delay modules through it (I think it was the Modcan Dual Delay)

I had a sound going through it which had varying resonance, and the feedback of the delay was also being modulated/ tweaked. You can see where I'm going with this - that's right, huge bursts of uncontrollable resonance/ feedback! (especially when the two things coincided)

Solution: stick the output through the Optodist! If set to a "sensible" - ie: non-distorting - setting, with the limiter engaged, the end result is some tasteful limiting. If you set it on the verge of distorting, you get some amazing, tearing distortion whenever the delay's output goes haywire....but, due to the limiting and clipping within the Optodist, the output level stays relatively static.

Great little patch, and one I recorded....so I'll upload it when I get a minute thumbs up
VT
Hello guys!

First of all - great video! made me lust for one of these grin

Second, I have a VCA question. Does this module behave well as a VCA?

My planned setup includes a Disting, a Modemix and a Optomix, all of whom can function as a VCA but are not dedicated VCAs themselves.

My question is: Can I add a Optodist to my setup and get away without a dedicated VCA, or do you think I desperately need a dedicated VCA in my setup? I really much like the idea of having multi-funcion modules.

Thanks in advance! Guinness ftw!
ben_hex
Hi VT

I'd say you would want a normal VCA that isn't something else that can just function as a VCA. That said the Optodist is fantastic! Works great as a VCA with the added saturation and distortion options. I'd definitely want a clean more basic VCA though. Luckily for RYO fans (I'm certainly one) they are working on a 4hp triple VCA module that's coming soon (if I remember right).

Feel free to message me to chat about your plans and set up anytime.
cold_fashioned
A 4hp triple VCA?! Well, how do ya like that? Thanks for the hot tip! hihi

Just picked up a used Optodist after watching your video (several times). Great demo!

It's peanut butter jelly time!

I was lucky to get a DIY-kit which I soldered yesterday. I say lucky because I absolutely love how it works on my sources.

Example: Saw VCO -> Multiple moving BP-filters -> Optodist -> LP Filter.

Absolute yummie!!

That's a great signal path. Rich wave, carve it out with filters / EQ, distort and filter again. Definitely into that signal chain smile
