This is the Best random click I have made in a long time. Very,Very interesting and definitely worth investing some time and money in. Thank You so much for the upload and demo of the Project.
Glad this popped up in my feed - thanks for making this video, and hopefully this becomes and off the shelf product
I’m considering modding my Digitakt 2 with a daisy seed as an internal digital synthesizer that can be controlled by a midi channel.
Very cool . . . thanks for posting. In an ancient epoch, decades ago, I was designing and building various analog synth modules (lots of op amps, integrated linear devices, CMOS logic and all that), even designed my own PC boards (long before there was any CAD software for this), it's fascinating to see how far the DIY design universe has evolved since those primordial days. It's a bit beyond my current pay grade, I just like to use the current tech rather than be submerged in perpetual prototyping, but very much appreciate the current DaisySeed concept / design strategy and this project.
I would agree! I "grew up" using op amps, various digital building blocks, and so forth, but I moved into microcontrollers fairly early (Z-80, 8051, various Microchip and AT chips--but a lot of these companies and their products have been recombined & renamed). Now I look at ESP32 for most of my automation devices. I'm just now wanting to build some music processors, and have found the Daisy.
Thanks for making this video. This Github project might save me a lot of trouble to have some shoulders to stand on, to get to something useful quickly.
This is all above me and not part of the skill sets I have picked up through life. I’m just the user of the end results, which I must say sound great and very unique. Nice video!
Wow. This is getting close to what I’ve been dreaming of for years - the ability to load chains of VST effects. I’m not a programmer, but if I could install standard DAW plugins into a pedal, authorize with my ilok, and use in my guitar chain, I’d be all about it.
empress zoia
For real!
Poly Beebo ;)
Hoy long until One can just get One out of the shelf? Absolutely love the concept
This is extremely exciting, will be keeping an eye on this!
Tasty tones! The VerbDelay put me very much in mind of Devin Townsend and the Mooer Ocean Machine pedal, which I have always wanted to reverse-engineer (read: wanted someone to build an opensource platform with as many knobs). Glad to see you put your RPi neural modeller in it, have always been a little dissapointed that it never got much traction (compared to NAM which went absolutely crazy for no particular reason). I still have the PC version in most of my signal chains for when I just want a reliable amp emulation.
I'd really like to make one of these... its absolutely awesome sounding!
Imagine if the music community could crowd preorder a first open source hardware multistomp with several stomp buttons and fade/wah pedal programmable to 200+ settings,
right&left+bypass outs...
An ever customizable multistomp for life!
That looks like something I need to build. Great little pedal for sure!
This is what so much pedal tech has been leading to- a DSP box into which you can load whatever crap we've accumulated for way too long haha
Yeah, I was sorta surprised we haven't yet seen something commercial yet that does this. Most digital guitar pedal fx hardware is fairly similar under the hood. Some controls, some buffers, and then something to do DSP. Really the magic of all these pedals is in the software. Software that could probably run on anything. One of the reasons I set out to build this is that I simply wished that there was a sorta of universal little box that you could load cool software algorithms onto. Would be nice in the future if some of the big pedal companies like Empress, Meris, Strymon, etc could just sell you the software plugin to run on whatever hardware...
it's what most digital pedals are already, just closed source and massively overpriced.
Where can I get this and for how much money? Seems mysterious on how to get one. Do I go to your website for instructions & information on who is selling this? And is it the same open source software that’s big talk for computers? It would be nice if we could do this with our iPad and if we can, can you guide me?
Seems like open source changes everything including how we look at Guitar gear or any gear,.. but I’m wondering if some of these modules can be stacked. I’m blown away by how much things have changed with open source technology and it seems like if you can’t stack these algorithms, it would definitely be worth to get two pedals and hopefully a discount on the second one. If these can be stacked in one pedal with just two or three programs or algorithm at a time then that’s crazy fun and possibilities, even if they can’t be stacked it seems worth getting with all sounds I’ve just heard. Watch out strymon & modeling companies that aren’t allowing us this to do this. But I just saw a video on Anderton signaling that one of the modeling companies is planning on allowing open source algorithms to be loaded so they’re starting to catch on and even offering synthesizers inside their modelers.
Got to ask yourself - do you want to play guitar or spend all day tweaking shit ? Very clever but also distracting.
You are about to change the world!
This is amazing, I would love for this to just be a commercially available product. I ended up writing something in JamOrigins Midi Guitar 2 plugin maybe over a year ago that I'm happy with, but had no way to really translate that to a pedal since my knowledge of electronics is pretty limited. But if the hardware portion was solved, I could have something on my pedal board that would be sick!
Howdy! I’m here in Huntsville and I just found out about this project through UAH, if y’all need some professional guitar playing and use of this in a full recorded mix, I’m happy to help out! I’ve been wanting an open source digital effects platform for sooooooo long. It even has studio use cases, like using it as an outboard limiter or bus compressor! Wow that vocoder was soooo cool too!
That’s awesome, working with UAH was one of the most rewarding experiences to come out of doing GuitarML. I will keep your offer in mind! And stay safe in this icy weather!
@@GuitarML for real! Y’all stay safe too!
Incredible stuff! No surprise at all that that the brains of the pedal turned out to be the DaisySeed. I got one and a DaisyPod to fiddle around with a couple years ago. Great fun and superb tools for learning! May just have to splurge on one of these pedals. I'm working on a similar project. How does it handle writing to the OLED screen without interrupting the audio stream? My audio stream uses I2S, DMA and a circular buffer and it worked great until I added a screen. The MCU (STM32F405) uses SPI and DMA to send the frame buffer to the OLED display (SSD1327 driver). If I draw too many pixels on the screen, there are audible glitches where the audio stream is interrupted. I realize this really isn't enough information on the system, but I welcome anybody to chime in anyway. Thanks!
The drawing calls are made in a thread with lower priority than the audio callback. If the DSP processing load is too high, drawing will lag, but not in the other direction (no amount of out-of-audio-thread processing can hang the audio thread). Indeed the display is connected to the Seed's SPI pins.
Currently I'm working on DMX controller which reacts to sound. It has 3 band IIR filters and ST7735 64k color 160x120 pixels screen. I created ultra fast library using DMA and screen buffer. So ultra fast solution to display anything is use screen buffer then sending whole screen content using DMA. Couple of years ago I also worked on simple DSP using STM32F2 but those processors were buggy with problem with I2S.
@@aloiscerbu Thanks for the replay! The deeper I dive into this, the more I'm beginning to think I may need to make the swap to FreeRTOS.
Do you just have the audio on a higher priority thread than the display?@@Marcink126
Really cool project!
Pretty cool, I was going to aim for something simpler, like raspberry pi zero running elk audio and just have 1 vst effect that can be controlled via physical knobs, but now I might want to give this one a try.
Innovation is cool. Be nice to have a NAM or Tonocracy profile loader in a compact pedal format. Cheers!
Yeah, NAM is giving me NUTS with the possibility available for musician. As an example of use case for me, you can just put an ready for gig favorite amp in a pocket, without needing of transporting real amp to the show floor 🦄
Very good! Neat design and layout.
Cloudseed verb sounds great
Wow this is fantastic!
this is amazing
This is insanely cool, and definitely way over my head. I know very little about dsp or any of this stuff, but I can see the potential for how powerful this could become.
Like does this have the ability to run a vst? I’ve always thought it would be so cool to have a pedal like this that I could just load any vst effect from my desktop into it and have it on my board. But I’m not sure if this is the same thing.
This seems like a much better investment than buying something from a pedal company that can only do one thing. But I can also tell as soon as you started showing the software stuff that I would get really frustrated just trying to make the thing work instead of actually playing - I already have enough obstacles in the way of me practicing and recording.
So until the day a pedal like this is just available to purchase already built, and has some kind of basic editor tool for those of us that have no coding skills, I will probably stay away
I've got a daisy seed and this was exactly what I wanted to do with it, think i'll get one of the boards.
This is so amazing.
Is it possible to add more to it, for instance pianos, Fender Rhodes or even modeling.
I would cry
Wow, I can see the future of this type of pedal, Good Job!
Remember to name this pedal😏
Ditto! Wow, thanks for sharing this, ideal for lofi and the lofi pedals can cost quite a lot, this is brilliant......😃
I'm assuming Cloudseed is like a Cloudburst. Sounds really cool. This an awesome pedal!
I've been wondering when this would happen. I suspected someone would start making Raspberry Pie pedals years ago.
I wonder what that the latency is.
Going to order and build, thanks so much for showing this.
I wonder what latency it normally has when engaged.
Lets get a stereo version!!
The pedal is stereo. input & output are TRS stereo jacks.
@@keithshepherd is it possible to simulate stereo amps?
@@zacharykim295 Probably, someone would have to code an amp & cab simulator as an effect module for it, but I don't see why someone couldn't do that.
Coders be selling their small effect modules as private enterprize. New concept with endless possibilities.
A question is though if different modules or "plugins" would be compatible or easily not compatible?
how does this differ from the Mod Dwarf, which can utilize Neural plugins?
Cool project idea. My only concern is latency. I currently enjoy the Poly Effect Beebo unit but the latency is too much for changing patches on the fly. Best of luck with the endeavor!
I built a few of these in July using the schematics on Github. The pass-through latency (using modest buffer settings on the Daisy) is around 3 milliseconds, which is barely perceptible!
@@aloiscerbu i'm sure you could get it lower than that, though it would depend on the effect you were running somewhat
O wow, future already here, thanks)
amazing!
My mind has just exploded
This is the future of efx.
Very very cool. you are toughguy!
awesome job, I'll build one.
Let me know if you run into any trouble or have any questions
This certainly could be expanded into a processor unit to have chained FX such as Amp+IR with delay and reverb or EQ or whatever.
Yes! This is definitely an ongoing project that I’m hoping will start a conversation and get people thinking about the possibilities.
You can definitely setup the software to run multiple FX chained on a single device. There are some practical limitations in terms of processing power and memory usage for each effects, but the Daisy Seed powering the pedal is quite capable.
@@GuitarML it seems like there is such a barrier to entry with this pedal. I'd like the exact one in the video but this is my first time seeing a schematic or a .cpp file.
Thanks for your time!
Grey zoom pedal ms 50 g is fun and has some great sounds
So where can I just order a KIT with most or all the parts to build myself? Seems like a simple request, right?
so it´s a open source Line6 HX Stomp with less functions - The stomp is 5 years old so the new thing here is the opensource that is kind of cool - But how good are the DSP´s and the IR´s
Hello, do you know of a way to get the original plugin working on Mac with Reaper? I really miss this plugin since switching from Windows, especially the Rubi-Ka Fields preset. It was a great writing tool to drone away and get lost in. You seem to have an advanced knowledge of how this works, so any info would be greatly appreciated!
Where can we buy this pedal??
I wonder if you could implement Airwindows effects into this. I think it weould be awesome to have nonlinear space in a little hardware box (it's my favorite reverb)
like all multi effect pedals ever?
Anyone have a rough idea how much $$$ the BOM would cost to assemble one?
So ordering from JLCPCB requires a minimum of 5 assembly pcbs, costs around $175 for 5 of them, not including the daisy seed, remaining soldered parts and enclosure, knobs, etc. So all told I think it would be around $120 per pedal, making 5 at a time, depending on shipping and all the variables.
@@GuitarML what about premade?
Imagine that would accept JS effects. BTW the amp models sound very convicing
Does Tom Scholtz know what you guys are up too? Just kidding, this looks insanely cool. I have a ton of question, but I think I'll read through the source first.
Great! Do you have a latency number, or can tell if it's something noticeable?
Where can I buy one built already? Thank you.
I do offer some of my extras as kits or complete pedals from time to time, but since this video has blown up, I'm currently out of stock. I'll be ordering more soon though, if you reach out, I can add your name to the list.
@@keithshepherdim also interested in buying one! Btw, how much does it cost?
@@LuisbxkxnndI'm currently selling full completed ones at $150 + s&h. Basically at cost since it's prototypey and not a commercial product.
Linux user + Guitarist here. Will I ever see some Linux compatible music software? I don't want to use Windows, for ethical reasons too, so that would be great.
@DanteS-119 Do you think you're funny, windows fanboy? Fuck off.
There's actually some, I only know of Wavelab
You could use Wine, to install Windows software on your Linux, but if you don't want that, you could try Guitarix for guitar amp, Hydrogen for drums, LMMS as DAW.... There's more that I can't remember right now 🙂
@@danpedersen55 You need a NASA supercomputer to use Windows software with Wine, it's heavy AF. Hydrogen doesn't have real time programming.
How much does it cost?
Cool!!!
Could it run nam?
It’s on my list of things to try! My guess is that it would have to be at least the nano models, if not a smaller custom size model, in order to run on the Daisy Seed
Must. Not. Buy! (I'm on a kit buying ban, but really, this seems like a no brainer instant purchase)
excellent is this stereo?
Does anybody sell this pedal? I want to run my own C code on a pedal like this but I don't want to take the time to build the hardware. I just want to buy it ready-made.
Can I buy one fully made and configured or is DIY the only way?
Look for the "Ordering Information" links on the main Github page, you can inquire about it, but the quantity is pretty limited. Possibly if more people build these there will be some units floating around to buy, when you order from JLCPCB you have to do a minimum of 5 units, so anyone making these will probably have extra might want to sell.
A minimum order, let's get 5 people to make an order together. I would def get on that train.
yeah defo count me in
just checked, apparently electrosmith make a dedicated guitar pedal as well
@@ValirAmaril If it's the Daisy Petal, that's been discontinued. Hoping they will revisit it or something similar though
Autopan was only mid to ringht, I could not hear its 'left' automation. Can we upload (code in) custom Amp+IR profiles, such as .nam files?
I think it’s just that particular oscillation mode, I didn’t explore all the settings. Right now it’s a manual code process to get IRs and models in there, but yes you can do that. Haven’t tried running NAM.
@@GuitarML Then your .json tone packs maybe? I just tried Proteus with the community pack and it is spot on! Amazing!
Thanks! Those tone packs won’t run on this pedal, it’s a matter of processing power, I have to tailor the size of the models specifically for this device. If there’s enough interest I might make a tone pack for this though!
There are two modes to auto-pan. One that is expecting stereo input and one that is expecting mono on the L input only. In this video the setting was set to stereo input, but there was only a mono signal on the input. That's why you only hear the signal on one side, it was just the wrong input setting selected. If it was toggled, you'd hear the mono signal bounce L to R as expected.
@@keithshepherdthanks for the explanation!
I'm still waiting for someone to make a pedal that you can load vst or plugins onto so you can take whatever plugins you want on the go. It's coming, I know it and whoever makes it will make alot of money. This is cool, but not quite there yet.
Since VSTs are DLLs, they are compiled code (just like a Windows program exe, except without an entry point: they can; be run on their own, they have to be accessed as a library of compiled functions from a running host program). The VST DLLs are compiled for the x86/x64 CPU architecture, so using the same VSTs you use on your computer would mean the pedal would probably have to be built with a x64 CPU, unless there is a viable work-around, like writing a decompiler/recompiler for the instruction set that VSTs use or something like that. That is why you haven't seen it done yet: no one want to put an x64 chip in a DSP pedal.
Before I set out designing this pedal, I also wanted something similar, but as @gibgezr mentions it's actually more of an issue with VST plugins needing x86/x64 to run on, which is much trickier to get running in a small pedal format with windows running on it. That's why I abandoned that idea and started investing time and effort into the Daisy Seed platform.
maybe the future will hold some advancements that could allow it. I still think it will happen eventually, Theres too much money to be made on something like it. To be clear, I dont expect something like it to be like 200 bucks or something. Id expect it to be closer to 500-700. The fact that theres already computers that are available that arent too much larger like the Apple studio or macbook mini and on pc side theres all kinds of mini pcs for under 200 bucks is promising. Thanks for the reply.Your product is very cool.@@keithshepherd
Valhalla reverb pedal is my dream
@@gibgezr Looking into my crystal ball I see a market for ARM-based VSTs. FYI, the Daisy Seed is an ARM Cortex-M7 MCU.
Is this for sale as a complete pedal?
At the moment, sort of. Through the GitHub page you can contact the author and inquire if there’s any extras available from him, for $150 not including the Daisy Seed. It will be interesting to see if anyone else takes it upon themselves to try to build and sell these, it’s a fully permissive license for anyone to do.
@@GuitarML thank you. I appreciate you and your time.
@@GuitarMLThis is such a cool concept and I'll definitely look into what it would cost to produce a few of these!
is there a way to remove the 1khz whine that I'm hearing?
I listened for it but couldn’t hear it, but doesn’t mean it’s not there, people have noticed that with some daisy seed builds in a guitar pedal configuration. Yes there are things you can do to reduce noise, both in the hardware or in the code.
@@GuitarML just at 10:00 min mark you can hear the noise, and there are many more such as 11:24-11:34 around there somewhere
Ah yes I do hear it there, yeah there could be some work done to reduce that. Ideally Electrosmith would come out with a daisy seed specifically for guitar pedals, and there was talk about it but not sure if it’s still happening.
@@GuitarML from what I noticed from the terrarium board, they don't separate digital ground from analogue ground with a 10R for example... which dramatically reduces the noise also, but still doesn't remove it entirely
@@siriusamplification I'll have to give this suggestion a try. Personally, I haven't had any noise issues with this current design, but I'm also using really clean pedal board power from a true tone 1spot pro unit.
I wonder what the latency is? I suppose it depends on what you are trying to get it to do, or how many things you are making it do. Is DSP programming just using a special library? I mean does it require a special ide or something?
From a quick look, it's C++ code with Visual Studio projects. You get direct access to each pair of samples (in stereo) in the process() function of an effect, with scaffolding code/classes to handle interface stuff; you can do whatever you want to the samples directly. If you've ever done any C/C++ DSP coding for anything at all before it looks dead easy to code up new effects, just looking at the code base. Looks hella fun, I'm verrrry tempted.
Oh, and @GuitarML posted in another comment that he was getting 3ms delay, which is tres fast.YMMV, I don;t know if it's dependant on your process() code or not.
@@gibgezr 3 ms latency is real small. I have done lots of programming including C++ and embedded but not DSP.
Latency can be quite low. The LibDaisy framework gives you the ability to customize both the Sample Rate as well as the Audio Block Size (which determines the latency) depending on the needs of your audio effect.
Is it possible to run multiple effects in series?
Right now each module is a standalone effect, if you want more effects you would code them into one module. Definitely possible to do multiple modules, it would just take some development work. The demo vid on the Github page sort of achieves this using multiple pedals.
cool
Can it run NAM standard files?
fine but does it run Rakarrack
Epic. :)
Wondering how this compares to the pistomp
Having built both, it’s hard to compare because they are very different. Pistomp has more processing power since it uses a RaspberryPi, but significantly more expensive. The other thing to compare is the Daisy environment vs MODEP. You can probably achieve similar sounds with either one, but the Daisy is so much easier and streamlined to develop effects for, in my experience.
Where can I buy one?
What kind of latency do you get?
I measured it at about 3 milliseconds; could be improved with better buffer settings!
@@aloiscerbu okay, and does it have a dry through option for delays?
The pedal runs in stereo, so you could actually program it to monitor the dry signal on the second channel. It also has a relay that can switch the pedal into true bypass, which directly connects the input to the output (in fact, audio will pass through unaffectedly when a unit isn’t powered
Great you're still alive!
This is cool.But it seems limited to one effect at a time?
I'm wondering if you're excited about the PiStomp Version 3 with raspberry pi 5(8GB).
Congrats, this is amazing! Can you tell how it behaves for a bass? is it low end friendly?
Yes! I use five of these as a live bass processing rig! Happy to share a clip if you wanna hear em.
@@aloiscerbuthat would be great!
@@_j0n3 Here you are! ruclips.net/video/cPfASGWupYY/видео.htmlsi=mVqy07bwJVjCShmk&t=68. The effects I'm running are a bit more ambient-focused (I use these in a band to make interludes between songs).
This is super cool! Thank you! @@aloiscerbu
I'm not even smart enough to buy this pedal... Ugh! Any advice? I want the exact one in this video!
Thanks for your time!
oh it is powered by Daisy Seed ???
yup!
Bro I want to buy this
This is higly interesting, but unfortunately at the moment it doesn't seems so easy at all to get the hardware pedal to start the journey...
I do sell kits or finished pedals basically at cost when I have extras, but unfortunately, I'm out of stock on everything at the moment since this video blew up. If you reach out, I can add you name to the list for the next batch.
@@keithshepherdPlease I would love to support this! Where could I give you my details? 😮
I didn't see an expression pedal input. That would be mandatory. So I could finally have a flanger that uses my foot as the oscillator. As opposed to just being used to set parameters like every other pedal.
I does seem like an oversight. I suppose you could use a midi pedal of some kind.
Expression pedal input is a planned feature in the next version!
@@aloiscerbu how much does the premade pedal cost?
They’re not for sale premade; I had five manufactured in July. All told (shipping included) the total cost was $150 per unit.
The next version of the pedal hardware will include optional expression pedal input. I didn't include it in the first iteration because I personally primarily use midi to control parameters, but I agree it would be nice extra flexibility to have and it's simple enough to add as an option...
i want one
Are strymon pedals a con?
I can finally start selling my real April fools mf106tc that actually seems like it works. Lol just set this bad boy up to run an algorithm that predicts what you’re going to play.
Another "take my money!" case.... 🙂
Yeah, but does it have a banjo patch? 🤣
Can you load Helix snapshots?
wtf?
Is it me or this thing sounds less detailed and lower in quality than something like big sky or emperess reverb(or even GFI Skylar)? It's software or hardware issue?
I feel like comparing an open source platform made from off the shelf components with a bunch of plugins loaded into it to some of the most advanced units on the market, which have been designed specifically for a specific purpose and likely have a bunch of proprietary components and/or software optimisations that take advantage of the hardware may not be entirely fair.
If you want it to sound like the best units on the market you might have to wait for the platform to be adopted by enough people for someone to work out how to get that sound quality, or possibly for some hardware revisions to upgrade the components as new chips become accessible.
What this will do is be a very affordable and professionally viable alternative to other multi fx units, with there being a potential for the pedal to be an all in one unit that can be hooked up to a midi controller - allowing you to automate a bunch of parameters and move between patches without needing to take your hands off of your instrument.
Edit: you can also load VSTs onto it, so it's possible to make it a fully functional synthesiser suite if that's your thing
Strictly speaking it can’t host VSTs as is. If the VST in question is open-source it ought not to be so hard to port the DSP code to run in the Seed, and then map the parameters to the physical controls. But the Daisy Seed doesn’t even run an operating system, let alone a DAW / VST host.
legendary, also first comment!
Awesome project! The sad part is that it's only a matter of time until some design thieving company like Joyo clones all of this and the patches and sell it as their own.
You mean the great part !
(first: it's open source, so nobody is in it to make money, and second, in the current state likely only a few people will actually make and use this pedal)
Anyone selling pre-built pedals?
I do sell kits or finished pedals basically at cost when I have extras, but unfortunately, I'm out of stock on everything at the moment since this video blew up. If you reach out, I can add you name to the list for the next batch.
Please put me on the list Keith
it sucks that I'm too dumb for this...
Sorry, I didn't watch the entire video....
Are there presets you can make? If so, how many? That's a lot of options to have to hunt for each time you want to use the same settings.
So does your mom
