Thoracius Appotite’s MicroKORG Patch Pack

Play the videos to hear demonstrations of the various patches in the pack. (Disclaimer: I am not a keyboard player.)

In the YouTube description there’s a clickable index of the patches, so you can jump around.

MicroKORG Patches

Despite its measly four-voice polyphony and limited patching options, the MicroKORG is the most popular synthesizer of the past decade and a half. This is probably because it was the first digital synthesizer capable of producing a convincingly analog sound. It’s capable of a far wider range of sounds than analog synths of old. It’s also extremely portable, making it easy to tour with. The stock patches, though, aren’t terribly useful for musicians working outside of EDM. They’ve also aged quite a bit over the past decade and a half — so here I present you with some new, fresh, original MicroKORG patches.

Classic Vintage/Retro Sounds

In this pack of original patches, I’ve emulated famous vintage analog synths (Minimoog, Polymoog, Moog Modular, Juno, Jupiter, Buchla, EMS Synthi, CS-80), retro digital synths (DX7, D50, SQ80, Casiotone & Portasound), vintage keyboards (Mellotron choirs, Farfisa organ, Clavioline, Wurlitzer electric piano, analog piano, Eminent string machine, Hammond organs, Clavinet, Harpsichord), as well as some acoustic sounds (toy piano, marimba, church bell, male baritone voice).

For some of these synthesizer sounds I’ve drawn inspiration from artists such as John Carpenter, Tame Impala, Giorgio Moroder, Edgar Froese, Tangerine Dream, Jean Michel Jarre, Isao Tomita, Survive (Stranger Things OST), Angelo Badalamenti (Twin Peaks OST), Air, The Cars, Clio, The Doors, Stevie Wonder, Led Zeppelinn, Mac Demarco, Wendy Carlos, Gary Numan; and styles ranging from electronic avant garde, kraut rock, new wave, horror/soundtrack, electro pop, space disco, garage rock, psychedelic pop, dream pop, ambient, new age, and various kinds of pop. There are leads of every kind, ambient pads, phat basses, electro drums, horns, arpeggios and sequences — all sorts of sounds.

It’s a Pretty Good Deal

The pack contains roughly 130 hand-crafted patches, and costs only $24.99. Think about it this way: You’ll only need to sell a couple copies of your album to recoup that expense.

Buy Now via PayPal

(Email me if you’d prefer to pay with a cryptocurrency.)

Thank you for your support. Please, if you have any requests for patches you want me to make, let me know. I’m always working on new patches, and I want to make this pack as appealing as possible.

Demonstration Song

This demo was created five years ago when the pack contained far fewer patches. No external effects or processing has been used. I’ll try to record some demo songs with new patches as soon as I get a chance.


Are you still selling these?
Yes! The file will automatically download once you’ve paid via PayPal — so complete the checkout process, and don’t close the window before you get to the receipt page, and if there’s a link for “go back to the vendor’s website” or something along those lines, definitely click on it. If for some reason it doesn’t download, just email me and I’ll get it to you. I try to check my email at least once every day, but sometimes it can take me a few days.

What format do you provide the patches in?
Four different formats to give you lots of different options depending on your circumstances:

  1. Individual .PRG files for each patch – native patch file format for the Windows KORG MicroKORG Sound Editor software.
  2. Individual. MID files for each patch – these contain SysEx data to use with SysEx Librarian (Mac) or MIDIOX (Windows).
  3. Bank of 127 patches as a .SET file – native bank file format for the Windows KORG MicroKORG Sound Editor software.
  4. Bank of 127 patches in the file format for the Mac MicroKORG Sound Editor software

I recommend loading the individual patches, so you can decide which ones you want to load into which memory slot.

How do I load these patches onto my MicroKORG?
The easiest way is to use KORG’s free MicroKORG Sound Editor software to transfer the patches from your computer to your synthesizer via MIDI. If you don’t already have one, a USB-MIDI cable costs less than $10 these days, and will save you hours of work. If you run into any trouble, check out my troubleshooting guide.

I don’t have a MIDI interface. Is there any other way to load the patches onto my MicroKORG?
The amount of time you’ll save is worth the $7 it costs to buy an inexpensive USB MIDI interface such as this one on But if you’re hellbent on mindnumbing repetitive labor, for the original patches in the pack I have screenshots you can use to manually enter the values into your MicroKORG using the “Edit Select” knobs. I’ll try to make time to take screenshots of the new patches as well, and if you have any special requests I can start on those.

Will these patches also work on the MicroKORG-S, MS2000 or the MicroKORG XL?
They are compatible with the MicroKORG-S and all variations of the MS2000. The XL has an entirely different sound engine, but I also have a patch library available for the XL.

I already bought the patch library from you a while ago, but you’ve since added so many more cool patches to it. Can I have those too?
Yeah, no problem, just email me.

    hi! i tried to contact you via email but i got an “undeliverable” msg back! anyway, i purchased your patch pack back in late 2015 and i’m very interested in these new patches! please respond when/if you’re able, i’d love to get my hands on them : )

  2. Kevin A. McLemore says:

    I purchased the patches and followed the installation instructions, as well as those associated with troubleshooting, but I cannot get the patches to load on my MicroKorg. I am using a high-quality USB-MIDI interface (Roland Um-One mk2) and the most recent version of Sound Editor. When I attempt to write a patch to a particular preset (e.g., A71), the preset is replaced by the default sound that is produced when you initialize the preset (Shift + 3). Has anyone had this this problem and if so, how did you solve it? Thank you.

      • Kristoffer Friis Knudsen says:

        make sure you put the patch files in the”my library/microKORG” folder. they have to be in that folder for the microKorg sound editor to load them.

  3. Dillon says:


    I bought your patches in December and love them.

    I am trying to use your youtube video to figure out which ones I really like (and how to use them properly ie. long chords, short choppy notes)….But the names of the patches in your video differ from the names of the patches in the actual zip file I got from you!

    Do you have a way to let me know which patch is which from the youtube video to their names in the zip file or microkorg software?

    This would be a huge help…I know I’m asking for a lot.



  4. Matthew says:

    I bought your patches a while ago and they are fantastic!

    But I’ve been having a problem with my microKORG recently and was curious if anyone else has run into the same problem, as I haven’t found a solution online yet.

    For some reason I can’t get the write protect to turn off all of a sudden. I’m doing the shift+8/knob 1 turn to off/and 8 again like I am supposed to, but the change is not saving. It says original value on “on” still and the write protect stays on. So my synth is stuck with the current patches and I can’t use the sound editor.


  5. Sadside Project says:

    hi Thor, we bought your set of patches and we were wondering if it’s possible somehow to transfer it into the library patch of garage band, so that we can use it with any midi keyboard.
    Thanks a lot

    • Thoracius Appotite says:

      Yeah it’s somewhere round 130 patches — everything from the demonstration videos. It should download automatically. If there’s a link to return to my website after you’ve paid be sure to click on that. Otherwise email me and I’ll send you the download asap.

    • Bandry says:

      Hi !

      I recently buy your microkorg patches library, but i would like to know where can i find your screenshots to edit my MK with editor knobs? I’m french and i don’t understand very well the midi technology and the microkorg software so this is why i try to do it manually !

      Waiting for your answer,

      Léandre Bandry

    • Dean says:

      I just purchased your microkorg XL patches and they sound great. Amazing!!! Any chance you could create the synth in “Everything in it’s Right Place”.

  6. Struan says:


    I’ve been trying to buy this for the last half hour, but just get a Paypal page that reads ‘We aren’t able to process your payment using your PayPal account at this time. Please go back to the merchant and try using a different payment method.’

    Any idea why this might be? The funds are there fo sho! Anything to do with being non US Paypal you reckon?

    Thanks in advance!

  7. cstinsonh says:

    HI! Bought your awesome patches a while ago, but just saw that you have some updated sounds. I tried to email you but unfortunately it wouldn’t let me. I am definitely interested in the updates

    • Thoracius Appotite says:

      Oh yeah, you’re O.G. — bought these in 2015! You’re in for a surprise. 🙂 Just sent them to you.

      Strange it wouldn’t let you email me. I wonder if I wrote the wrong email address somewhere or something? What happened?

  8. A says:

    Thank you so much for the amazing patches. It sounds amazing, was easy to handle and everything was handled very professional.
    10/10 would buy again!

  9. Rick Moore says:

    Just downloaded the “NEW” sound bank from Korg and yours are waaaaaayyyyyyyy better! They should be paying YOU to create their downloads!

  10. Rick Moore says:

    I was shocked at how easily this batch loaded into my MK in one shot from my Macbook Pro! It was simple and took less than 10 seconds! As far as the sounds go, it beats the factory sounds in my opinion! This is a great deal for the money. Thanks for all the hard work you put into creating these and for making it such a painfree process to buy, load and enjoy!

    • Thoracius Appotite says:

      Hey, Rick, It’s such a pleasure for me to be able to create something that other people appreciate and can get some use out of! So thanks so much for the compliments. Feel free to spread the word, and let people know about my patches.

  11. Toby C says:

    Hi there,

    I’d like to buy your sounds but do not want to transfer them on my microkorg using the Korg computer software.

    Would you be able to send screenshots of the parameter settings so I can enter the sounds manually?


    • Thoracius Appotite says:

      Yeah, I haven’t taken screenshots of every patch yet, but all the good ones and every one that people have specifically asked for so far. So I’ll send you what I’ve done so far, and if there’s any missing that you want just let me know and I’ll do them ASAP.

  12. Skaterdays says:

    Is there any chance that there is a text list or PDF of what sound is on what program number on the MicroKORG program selector A side and B side?

  13. Anthony says:

    Hello, I just ordered a microkorg s and love the way your patches sound and want to download them…I currently only have a iPad, newest one that’s supposed be like a iPad Air that’s just called iPad, can I still download the pack on the iPad and transfer them to the microkorg from there? I’m not sure how. I see a lot of patch editor apps but I would like to be sure before buying one of them.

    • Thoracius Appotite says:

      I’m not sure if you can use your ipad to manage patches for your microKORG. You would need an adapter that concerts the usb to midi and an app that sends sysex messages.
      What I have done though is take screenshots of a bunch of the patch settings, which you could use to manually input the patches onto your microKORG each parameter one by one. It’s tedious but it works.
      I’ve yet to the screenshots of all the patches in the pack, but I’ve done most of the best ones and am Woking on the rest when I have a spare moment.

  14. Jakobhallsson says:

    I’m trying to keep my sounds original, but I came across your E-piano (Rhodes) sound and it’s just amazing.
    Any chance I could buy just that one from you?

  15. Gregos says:

    Hello, I´m not currently in the u.s.a. and don´t have the paypal service, so for me it would be very helpful to have the screenshots, how can make the payment and get those? also for the update

  16. Matthieu says:

    I just bought your cool collection, tried to load the patches on the microkorg with my mac and a USB midi-connector but still not able to make it work.
    I tried with Microkorgeditor, but I think I need a patch file like in this video : as I only have .mid and .prg in your pack
    I also tried with Sysex Librarian, followed all the instructions but in the end I am unable to save any patch on the microkorg…
    Could you please help me ?
    Thanks a lot!

    • Thoracius Appotite says:

      That’s a tough one since real harmonicas are inherently so expressive. Synth patches emulating harmonicas tend to be kind of cheesy sounding. What kind of harmonica sound do you have in mind? I could give it a shot.

  17. Shane Gallagher says:

    i’m planing on buying this amazing pack soon with my friend who plays the microKORG in our band. It’s our first time adding patches to the synth, so its very helpful to have the breakdown of that process on this page!!

    If you are still taking requests for additional patch sounds, Have you thought about exploring more mellotron type sounds? maybe some mellotron strings and horns? and the classic flute. The chiors you have are very nice!!

    also could I request the Gary Numan signature Vox Humana sound from the PolyMoog?

    • Thoracius Appotite says:

      Great requests, Shane! I’ll have a go at these next time I have some free time to sit down with the MicroKORG. Mellotron sounds are hard, since the elements that make them so distinct (actual instrument performances and lo-fi tape frequency response and saturation) don’t have direct analogs in the subtractive synthesis paradigm. But you never know, sometimes magic happens. The Polymoog Vox Humana is supposedly also nearly impossible to emulate, but that sounds like a fun challenge.

  18. Hans says:

    Just found your patches searching for a Marimba sound – although not entirely satisfied with the result – I am reeeally keen on a lot of the other sounds! And would like to support u and ur music!
    The sound that got me hooked on a marimba is this: any ideas on this regarding the mk sounds…?
    So I will buy your patches any minute – would you send me the screenshots AND the patches, as I don’t have an interface yet – but a friend has. 🙂
    Thank you so much for your work – keep on making good stuff and spread it!
    Best regards from Germany.

    • Thoracius Appotite says:

      Ultimately you’ll never get that good of a marimba sound or any acoustic sound out of a virtual analog synthesizer (or analog synthesizer for that matter). You can get closer with a FM synthesizer, but it’ll still sound cheesy and won’t be as nuanced. Your best bet is to find a good sample pack to load into a sampler. Have you tried asking that artist what she used?

  19. Rafoli says:

    Dear friend,
    I am really interested in the hammond sound.
    Do you have any more patches emulating that sound?

    Thanks a lot

    • Thoracius Appotite says:

      Hi, sorry for the late answer, but yes, as requested I just recently added a whole handful of Hammond-Leslie-style patches, quite a bit better than what I had before and better than the MicroKORG ships with, ranging the gamut from mellow to a hint of grit to full on fuzzed out. Most of them you control the simulated speaker rotation speed by turning the tempo knob.

    • Thoracius Appotite says:

      Unfortunately, no. I’ve tried, but the XL has an entirely different sound engine with different sensitivities to values and is missing some of the more pleasing characteristics of the old MicroKORG, namely the ensemble effect.

    • Thoracius Appotite says:

      Hey Nieves, I just expanded the patch pack, quadrupling the amount of patches. Check out the new demo to hear them. In the future I’ll probably split the pack up into separate libraries, but for now it’s one huge one.

  20. Alex says:

    Hello, I am getting a micro kor g tommorow and really like your patches. I’m pretty new to the world of synths so this might be a silly question. Can I upload your patches to my microkorg and then save them to the synth and use them without being pluged into a computer?

  21. A+ says:

    Hey buddy I really love these sounds as I am a fan of Stereolab and these sounds really remind me of their stuff. Can you email me both the patch file and the screenshots? How would we go about doing this? thanks!

  22. zeke says:

    Hi Thor, I cant figure out how to load the .pgr files into the soundeditor. It doesnt recognize them. I am using a mac. is this an issue? What is the process for loading the files into the soundeditor and placing them on the microkorg itself? Thanks.

    • Thoracius Appotite says:

      I don’t have a mac, but here are some instructions I’ve found and sent people that seems to do the trick: 14712&highlight=microkorg+prg+mac

      1. Install an application that can transmit .sysex messages in OSX. I use SySex Librarian. 2. Connect your microKORG to your mac using your midi interface. 3. Change the MIDI filter setting on your microKORG so it can receive system exclusive messages (p60 of manual, shift+4 then turn knob 4 to “E-E”, press shift or 4 key to confirm). 4. Play the .sysex file using your software.

  23. taman shud says:

    I have a midi interface but I’m not up to scratch with how to use the microkorg sound editor.
    If I purchased these patches could you send me both the actual patches, for when I learn how to use the sound editor, but also screenshots of the values of the parameters and the number of the original patch which you edited to get the sound.. A.53, A.54 etc

  24. taman shud says:

    is there a way I could manually edit some of the patches in my microkorg to get the sound of some of the patches on offer here?
    I know you’ve taken screenshots of the settings for each patch, but it doesn’t actually say the patch number of the sound I’ll need to edit in these screenshots, A.53, A.54, etc.
    would much appreciate your help.
    I’d really dig having some of your patches

    • Thoracius Appotite says:

      None of these patches are edits of factory patches. You can edit any patch to get these sounds — but you’ll have to change the values for every single parameter.

      I highly recommend using a MIDI connection to transfer the settings instead of manually programming the settings, as it’ll save you probably hours of work.

  25. David says:

    it’s David. I just bought your great patch. Can you send both patch and screenshot please ?

    Thank you et congratulation for that great job


  26. Evgeniy says:

    You should definitely remove that BUY button above the list of tracks and move PayPal button higher because someone like me can accidentally buy MP3s instead of Microkorg patches.

  27. Lucas carpenter says:

    I’m interested in purchasing these patches in the next couple of weeks. I saw the date on this was over a year ago so I just wanted to make sure you’re still selling them?

    Thanks a ton,

  28. Sattawat says:

    hey man i really wanna buy these patch from you but first i wanna know how to put .prg files to the microkorg sound editor
    please help me

  29. Bevan Glenn says:

    Hi ! I bought your patches (that sound way cool ! nice job !) but i do not have a midi interface, could you send me patches screenshots with the .prg files (i’ll try to set MIDI later, hard stuff for me !)

    Thanks, Glenn

    • Thoracius Appotite says:

      If you have a MIDI interface hooked up to your computer, you plug your microkorg into it. Download the MicroKORG SoundEditor software from the KORG website, and use that software to transfer the patches to your MicroKORG. You pick a slot on the MicroKORG and overwrite the preset with one of my patches (which you can always undo with the MicroKORG soundeditor software or with a system reset directly on your microkorg).

      I highly recommend getting a MIDI interface if you don’t already have one. Otherwise, the other option is to enter the patches manually into your MicroKORG setting by setting. This takes a lot of time. This is done via the two big dials and the other smaller dials on the MicroKORG. When you’re done you just hit “write” twice and it saves the patch to the current preset on the microkorg.

  30. richard avena says:

    hi. my name is richard and i just bought a microkorg and dont dig all the techno/dance crap on it either! i like your patches though! I am very new to synths and dont really know much about patches or midi. Would it be easy for me to program the patches onto my microkorg from your info? Lemme know!

    Thanks- RWA

    • Thoracius Appotite says:

      It takes time to enter the patches in setting by setting… if you value your time against an hourly wage then it’s probably worthwhile to spend $30 on a cheap USB MIDI interface, because it’ll probably take a few hours to enter all the patches in. And if you ever want to program your own patches, it’s much easier to use the software than the dials on the microkorg.

  31. miro says:

    hey there, great sounds 🙂 i like a few of them, but most of them wouldn’t fit to my needs. do you think it’s possible to purchase only a few of them (about 4 or 5)? this would be so great!

  32. JAMIE says:

    I think you may be doing yourself out of money with advice, the Microkorg xl can use MS2K, MS2KB, MICROKORG patches also. Just thought I would let you know that the engines are all compatible (pretty sure they are identical) and i know they all share patches as i recently used the factory microkorh bank in mt XL. all the best

  33. Gary Johnson says:

    Great work, but I own a microKORG XL. There are only 3 patches I can use right now: Hammond B-3 Leslie patch, sax / horn patch and a really good flute patch (ie Tull or can’t you see intro). I know you work on a different system but if you could build these for me I would be interested in a purchase.

  34. Ryan says:

    I got the patches today, thanks that was really fast! So far programed 3 and taking my time to hear how the sound evolves along the way. Thankyou for taking the time to respond, now I have a good better starting point. Peace- Ryan

  35. Ryan says:

    Hey man, patches sound way cool. I just purchased tonight on pay pal and wanted to request the screen shots. How did you learn to create all these great patches? I got my micro a month ago and having lots of fun with it but hard to find info on making own patches not just downloading w/ midi. Any advice? Keep up the sweet sounds. Blessings, Ryan

    • Thoracius Appotite says:

      The MicroKORG is an analog modelling synth, which means that though it’s fully digital it emulates the functionality of an analog synthesizer. So making patches on the MicroKORG follows the same basic principles as pretty much every analog and analog-modelling synth made since the 70s.

      The signal starts with an oscillator. This is just a raw sound signal. On digital synths it is called a DCO (digitally controlled oscillator) and on analog it’s called VCO (voltage controlled oscillator). Typically you choose a waveform that has the type of overtone characteristics of the sound you’re after. For example, a clarinet due to its construction produces mostly odd harmonics — so you would use a square wave as a starting point for a clarinet patch, since square waves have only odd harmonics.

      When you hit a keyboard button this typically does two things. 1. It controls the frequency of the DCO or VCO, thus changing the frequency of the note to match the desired keyboard pitch. 2. It triggers an envelop. Envelopes generally have four parameters: Attack, Decay, Sustain, Release (ADSR). Attack controls how fast the volume change from silent to full volume occurs. Immediately after reaching the peak volume decay determines how fast it falls to the sustain volume. Sustain determines what volume level to hold the sound at while the key is pressed. Release determines how long it takes for the volume to fall back down to null after the key has been released.

      The signal is also typically routed through a filter. The filter is essentially a very extreme EQ. Different synths have different filters. On the MicroKORG you have four to choose from. The 12db/octave and the 24db/octave are typically the most useful.

      Synths typically also have low frequency oscillators (LFOs). These are also wave signals, but are so slow (low pitches) that they don’t create a sound themselves. They are typically used to modify the DCO/VCO, for example, to add vibrato.

      On old analog patch cord synthesizers you were limited by how many modules you had, but you could patch everything into anything in any way you desired. The MicroKORG has only four patch slots where you have some freedom in assigning a few predefined controls to modify others. This is typically enough to accomplish a sound with nuance.

      Those are the basics… I’d suggest reading up on the basics of analog synthesis as a starting point and then apply these concepts to the MicroKORG. Hitting “shift+3” on your MicroKORG will initialize a patch for you to work from.

  36. Alex says:

    Hey, is it possible to send me the screenshots? I like these patches a lot, and I would like to use my microkorg more often since I don’t really like the patches that are on it. I don’t have a credit card or paypal so I can’t order midi cables.

  37. Larry says:

    So if you send the screenshots is basically what you’re sending me the things to enter im edit select 1 and 2? And will you send both screens and midi?

    • Thoracius Appotite says:

      Yes, from the screenshots you can deduce all the values to input using the edit select knobs. As you can imagine, this takes a bit of extra time to do, and if you value your time at an hourly wage, it’s probably cheaper to get a cheap MIDI interface such as the one I link to at the bottom of the post. And so yes, I’m more than happy to send both the screenshots and the patch program files, as it’s inevitable that some people will give up with doing it manually. 🙂

  38. Filip says:

    Hey man, i love some of these sounds. I’m very interested. But i don’t have a midi-connection, nor am i interested in one. Do you think we could solve this?

    • Thoracius Appotite says:

      Hey Filip, yes — I’d send you screenshots of all the settings and you’d manually enter them into the MicroKORG. Quite a few people have done this. It’s definitely not as easy as MIDI, but is definitely doable.

    • Thoracius Appotite says:

      No, unfortunately MicroKORG patches do not work with the MicroKORG XL due to the fact that they use a different synthesis engine.

      In theory these patches should all work with the KORG MS-2000 and MS-2000R, since that shares the same synthesis engine as the original MicroKORG.

      • Lauri says:

        Ok, it can’t be helped..Nice patches anyway!
        And JustAnotherSC sounds great too!!

        Here’s our instrumentalband from Finland 😉

        Have a nice day!

  39. Danny says:

    I would for sure buy this if you had an actual list of the settings. I don’t have a MIDI cable to plug it into my interface and don’t wanna go through the whole install thing haha.

    • Thoracius Appotite says:

      Hi Danny — I think I’ll try taking screenshots of the settings in the sound editor software when I next have a chance if that’ll do.

      Regardless, I highly recommend investing in a USB-MIDI connector… I think I got mine for $20 and that was a good five years ago. The ability to transfer and back-up patches on your computer is priceless, even if you don’t want to involve your computer in music making (software synths, max/msp, daws, etc.)
