My speakers shed years trying to reproduce these waveforms . Lol . So awesome .

[@travishayes6678]

The variety of effects coming out of this is ludicrous. Love it!

[@0RG457R0N]

thank you for this, I ordered 5 chips to make something cool like this.

[@jonathanclarke2582]

ahhh i see I'm not the only one who figured out the "garbage mode" lol! I accidentally put a 1Mohm pot in place and I got that, I used to crank the feedback with delay on what I call "broken mode" (same as your garbage mode) and you get weird uncertain patterns. used to run that into a spring for a horror music band I used to play with a lot. that delay also had a oscillator that went into the audio rate range and modulate the delay at audio rate, or like weird FM delay repeats. This look great Sam!

[@THISMUSEUMISNOTOBSOLETE]

haha you know it with the garbage mode! its golden, not heard it called that! good term jhaqjhqa. yeah its good at fm rates isnt it! this has a VC in so you can frequency modulate it :D.

[@sleepingkittystar9067]

id buy this tbh (if i had any money) this is rlly great and i love it

[@LP6_yt]

The bit with the chickens is brilliant.

[@silverXnoise]

Several years ago, I played guitar in the post-rock band The Farewell Monument and we used these absolutely terrible Chinese delay pedals called The Time Machine. They were Pepto Bismol pink, cost us $24, and sounded terrible but in the best lofi ways. The circuit they used pushed the PT2399 well beyond its specifications so it would sample and delay nearly 2 full seconds of audio. To achieve that they crushed the bitrate on the delayed signal so it quickly deteriorated, giving it a character similar to tape delay with severely damaged tape. With the feedback set to 100%, it exploded into a luscious noise that would damage your equipment if you weren’t Johnny on the spot with the Level knob to keep the volume within some semblance of reason-which was sometimes difficult because each unit we purchased was slightly different in its response and sound. They weren’t terribly reliable, but they were unique and absolutely crucial to the sound in a few of our songs, so between myself and the other guitarist we bought 6-7 of them just to have on hand. I still have 2. Awesome little units, I always have several PT2399s in my parts drawer because they are the perfect chip for instant lofi.

[@TRIPPLEJAY00]

Yes Sam that sounds awesome, maybe chuck in some punch button's for cut off or instant value change etc. Awesome build thanks for sharing.

[@THISMUSEUMISNOTOBSOLETE]

there are switches for that! not all of em. got a humungous delay momma on the way too tho :)

[@BenReichsteinSound]

Mate that sounds wiiiild! Great module, looking forward to it

[@rust2985]

This is beautiful

[@ExStaticBass]

Now all we need is a couple of Schmidt triggers and we're all happy.

[@ozerik]

Wow, I've never caught one of your unpolished experimental jams! Lovely!!!!

[@feliksjakubow8372]

listened to the whole thing with awe. you don't get this stuff with digital. absolutely inspiring!

[@mihalyponyiczki1855]

the PT2399 is a digital chip

[@THEREALDATALORD]

Sounds like some madness Joel Zimmerman uses. Beautiful module bruv

[@faramoftae]

Love this. Thanks Sam

[@Typical.Anomaly]

12:24 sounds a lil bit like the end of Nirvana- "Radio Friendly Unit Shifter" lol Whole thing is awesome, man! I have a handful of PT2399's that I'd like to use a 555 timer and an optoisolator on to control the "Time" aspect, i.e. the resistance that can cause extreme "pitch shifting" (kinda? lol). Or a CD4024 for dividing octaves until I get down to a few Hz and use that to PWM the LED in the opto? Idk, man. I'm drinking wine so I'll shut up... for now lol Love what you do!

[@sniggity]

I picture Richard Wright and Roger Waters in the studio making Dark Side of the Moon! Well done mate! You mind if I bounce a few questions off you when I start me builds? Have you tried guitar on it? Cheers, Casey.

[@lastavros]

mmmm... that overdrive is lovely

[@jimboburgess42069]

Having three chips plays to the strengths of the pt2399. I think one thing I would change with only one chip is the lack of a hard sync to a clock, it's not clean enough nor dirty enough, adding two more chips gets all that digital fighting going on making whole new things. Nice demo.

[@THISMUSEUMISNOTOBSOLETE]

I was playing around with sync and such. but I came the conclusion after adding a lot of bulk to the circuit, I thought to myself why would I sync a delay? the whole thing about having a delay with 3 delays is it goes out of sync. I am building these for my touring rig, but im nearly done with that synth voice, I have saved my findings on the sync functions for the more involved delay module im making in my "macro" module series which im gunna be getting to after the next 2 modules coming out :).

[@THISMUSEUMISNOTOBSOLETE]

but yeah 1 chip maybe sync, however I have never understood why one would sync a delay. for instance when im working in a writing session remotely at someones place and I need to use a computer for instance, the first thing I do is turn the delays of bpm control haha. it just defeats the object in my opinion

[@THISMUSEUMISNOTOBSOLETE]

however the first time I built one I was obsessed with the idea of syncing delays, so who knows. maybe we all go through phases of wanted synced and unsynced delays :D

[@pastoelio]

MFOS did a circuit with it too called the echo rockit

[@THISMUSEUMISNOTOBSOLETE]

indeed! funnily enough after I did this because im doing a vid on the other channel, I looked around to see how many have been made with pt2399's. and blimey there are a lot of em! not many with 3 chips in a none reverb setup. but yeah, I have found (not including the countless guitar pedals) mfos, cgs, befaco, Pittsburgh modular, synthrotek, just found schmitzbitz. it seems its is a very popular chip. the reason being is its super easy to work with. not the longest delay times, but it makes up for that with sheer strange character

[@Lalaland.001]

@@THISMUSEUMISNOTOBSOLETE are there schematics for this unit available, so I could build one myself?

[@arenotdiy7280]

14:47 is dope

[@kellymerrill8024]

Reminds me of the delay no more by Non Linear Circuits.

[@JAkoGreyshire]

take a look at NLC module called "Delay no More 3"....... schematics are normally available I think.... You might find some useful ideas..... I also have a video of the kind of fun on my channel using the original "Delay no More" module by NLC... Viva PT2399!!!

[@JAkoGreyshire]

ah, nevermind... I see on the new vid that you've seen the DnM3 already......

[@THISMUSEUMISNOTOBSOLETE]

@@JAkoGreyshire indeed! I only found that after I made this. but I checked it out nethertheless :DD

[@asciisynth]

Nonsense x 3?? That equals crazy!

[@asciisynth]

PS I have to build this. That digital garbage sounds brilliant.

[@CircularMirror7]

I been meaning to screw around with the pt2399 ICs I have.

[@Reprodestruxion]

Now for a revocar tape loop or it’s digital chip Arduino equivalent

[@stixvane]

I want one 😫😩😭

[@PWMaarten]

Disgusting. I love it!

[@illustriouschin]

Very interesting delay. Can you do Karplus Strong synthesis with this?

[@Zen_Mox]

I just got 5 pt2399s... like I wasn't going to listen to all of this... nice

[@johnnyboy2459]

"slowly stopped working" one sentence.... made in Chi-na

[@THISMUSEUMISNOTOBSOLETE]

haha more like "made in my workshop and strip board held to the front panel with insulation tape kind of stopped working"

[@crunchyfrog555]

Nah, Chinese goods can be excellent as well as poor. It depends on what part of the market you aim for. It's difficult because the usual online retailers are useless at denoting good brands versus bad, unlike here in the west. Think on this - the most reliable electronics in the world are built in China using Chinese components. The same stuff made for their own market is often complete shit. It's one of the weird ways China works. I recommend you go watch serpentza on this matter where he discusses how his DJMavic Pro drone caused him headaches when he lived in China.

[@johnnyboy2459]

@@THISMUSEUMISNOTOBSOLETE Maybe that too :D haha

[@feliksjakubow8372]

is there a way to somehow take the output and change just a pitch of that?

Want to Finally build my own! Wheres the list of the stuff/components that i haveto get before starting to weld? I allready got the lmnc 3*2399 chip with lmnc sticker!

[@THISMUSEUMISNOTOBSOLETE]

check out the link on the pinned. comment its the same schematic as the triple splash back

[@calabiyou]

Eurorack version prebuilt in your shop one day?

[@THISMUSEUMISNOTOBSOLETE]

hey calabiyou unfortunately I have come to the conclusion as of late to not jump into eurorack. I have a vision which I stand by that it is just too small, and I dont want to contribute my efforts to it, I strongly believe bigger and simpler is better. Kosmo modules are completely compatible with eurorack just the rails are a little further apart. Its built in the same way as eurorack so not expensive parts like 5u, and yeah just in my opinion more suited to music making. I hope that makes sense because as of late a lot of people have contacted me either requesting it or asking to strike some sort of business deal, and im gunna stand by kosmo. :).

[@256k_]

@@THISMUSEUMISNOTOBSOLETE would you be okay with someone making yoru circuits in euro layout and selling it? with full credit towards your circuit and open sourced?

[@undoubt1540]

Would it be possible to build one of these into a box, with a battery to power it. It's beyond me anyway. It's amazing. Love it.

[@etainafuzz]

@@256k_ I think that goes against everything Sam just said. Sam is passionate about Kosmo format and a lot of us have adopted it as well. Many of us have both Kosmo AND Eurorack modules and they will play nicely with one another. I think to take his designs, turn them into Eurorack when he has consciously not gone that route and not accepted any business deals to do so, and then turn around and profit off of said Eurorack PCB's is disrespectful. Just sayin'.

[@d42kn355]

yeeeessss!

[@OIP_1]

man check out NLC delay no more it is all about utterly destroying the PT2399. also your PCB designs are awesome
