This is a complete recreation of the Fairlight CMI IIx.

This has all the features of the original Fairlight CMI including 16 stereo voices, full voice editing and realtime control, harmonic additive synthesis, full Page R sequencer and much more.

Here's some live video captures of QasarBeach with no overdubs or added effects:

And... Made famous by Kate Bush. here is a QasarBeach take on her:

And for some  classic 80's dance culture why not try:

Here is a quick look at harmonic additive synthesis in realtime:

You get full file support for Fairlight Series I, II, IIx, III samples,  including all loop points, filter settings, etc. You just need to have the ORIGINAL files in .VC format.

Plus you get the following  formats as pure samples, so editing may be needed, but it gives you the power to access virtually all famous sample libraries from Emu, Yamaha, Korg and more:

  • .wav / .aif .ogg / .sam
  • .afs - casio cz1 sample
  • .ksf -korg-sample-file oasis
    .msmpl_bank -korg microsampler bank
    .p3k - korg
  • .usr - ppg
    .ufs - ppg
  • .xoe, .x0v .x0a .x0s .x0w .x3v .x3a .x3s .x3w - yamaha motif

    .iso -emulator iso
  • .out .s50 .w30 -roland s50
  • .bin - 8 bit binary files used by LINN and EMU for drum machine ROM

You will need to download all three files, especially the Guide which will tell you all about the very basic operations of QasarBeach.

The Fairlight CMI was a professional and complex machine, QasarBeach in no way tries to obscure this operation. So the UI is the same, the operation is the same, but there have been additions to make it a bit more user friendly.

QasarBeach is feature complete, but not completely documented. It is also being actively developed.

A HUGE thank you to all the testers and commenters. with you bug lists, wish lists and more :)

If you've ever wanted to have a go at your own music and want to know how The Art Of Noise, Kate Bush, Peter Gabriel, OMD, Yes, Hans Zimmer (and many many more) accomplished this in the 80's - QasarBeach is (almost) the way they did it!

Please feel free to add comments, thoughts, suggestions, etc. Nothing is out of bounds, so don't feel you might have a question that is odd, or strange bugs.

Nice work on this. I had some curiosity questions. For Linux do you use directly Alsa API or an higher API like openal (which would make it more portable) ? Thanks.

QB on Linux is a bit borked with the Midi not functioning - hence it is not up to date with the MacOS and Win version.

Internally it uses OpenAL and SDL2 with a custom sound-core sitting on top. The code base itself is virtually the same across all platforms ;)

Why did you remove the nphony? This makes the program virtually unusable for me. Are you planning on putting it back, or have you 'hidden' it in another location. I have looked around for it but was unable to find it.

Page 3, Voice

it was changed as this is where the IIx keeps it

Thank you, found it!

any chance a raspberry pi version will appear? (thanks in advance)

Hi Adam,

installed V1.26 on 2 different PC's, one exclusively reserved for Qasarbeach only, no other apps or programs installed. On both, Midi Keyboard doesn't seem to work anymore and can't switch between voices in Page R. Probably my bad, but wanted to share it anyway.

check the new PAGE O: Output mix and reset the faders - they are the new live master volume. Let me know if this works for you :)

Thanx, got it working. :)

Hi, thanks for this amazing tool! Any chance of the Linux version catching up to the Windows and Mac ones when 1.26 is released properly? It's two releases behind at the moment.

It's being worked on :)

I would like to thank you for bringing the Fairlight CMI experience to those of us who can only afford to keep the utilities going, the rent paid, and our families fed. Truly, I am grateful.

I've been lusting for a real CMI IIx, but was discouraged by its current selling price, which can be likened to an older home or a brand new car with a very basic feature package. I have tried a demo of Arturia's CMI software, but even then, having multiple workstations would require multiple licenses, let alone the excessive resource usage on even the most powerful computers; it really bogged down my quad-core laptop, to the point where it was literally unusable. On the iPhone and iPad, there are a couple CMI apps that are available for $10 and $50, but for years they've been riddled with bugs that the developer has yet to fix.

I'm very happy to have found QasarBeach; I'm surprised I haven't found it sooner.

thank you for the kind words. there is a facebook page where you can find others to provide more support and help :)

I have copied the files to the desktop on my HP Laptop, which is a few years old, and has a dual-core processor, running Windows 10 64-bit. The program opens fine, and all the functions appear to work, but when trying to save a sample made in the program to cv format, it mysteriously crashes the software. Also, I note that there is no 'quit' button. The Fairlight CMI had an OFF button, I'm assuming. Any plans to update w/ bug-fixes soon? I will attempt to run this again and see if I can save samples to other formats. This was a sample with loop points and polyphony enabled.

Re quit - just close the window :)

Please keep me informed if you can replicate a crash 

(1 edit)

I was able to save a looped sample in cv format, this time, so not sure what the issue was. Went out of the program and back in to check the cv file was still there, which it was. But the cv file apparently does not save polyphony and panning information. Is there going to be a fix for this in the future? Also one thing that would be VERY useful, is an 'undo' button for those of us who are a bit less technically gifted at programming code. My knowledge is pretty much limited to programming voices on hardware synths, particularly FM synthesis.

(it's .VC not CV). cmd+z will undo one step on most pages. polyphony is not part of a voice. a voice is a single voice. polyphony is many voices. save them as an instrument .IN. :)

My bad- I just started using the program and am not familiar with all the formats, or it could be that my old fat fingers don't type well on this little keyboard.  VC not CV, got it.  Thank you for making the distinction between an instrument and a single voice, that is very helpful. I will try that today and see if it works for me. There is an odd thing that the program does which is replicable, and that is when I go to add the voices to the slots 1-8, or A-H, it only brings the dialog up the first time I go into the screen. If I go out of the screen and back in to add more voices, I can't get the dialog to come up again. It says 'add', but no 1-8, A-H at the bottom of the screen. When I try to add another voice without that 1-8, A-H, it doesn't work. I end up having to quit the program and restart it to get that dialog back. Just letting you know. Thanks again!

I tried to install it on Windows10 64bit, but I can't install it even if I run qasarbeach.exe with administrator privileges. How do I install it on Windows 10?

it should run with no issues. The Facebook community may be able to help with this

Is it possible to say that the installation is completed with this operation?

In what folder is the program QasarBeach written, assuming the installation is complete?

(1 edit)

QB is 64 bit, and requires openGL. Do you have security software that might be blocking it?

Windows 10 is 64bit. No software blocks the operation of Open GL. I stopped the antivirus software and tried to install it, but the result was the same.

Open GL is Ver.4.3.0 because of GPU. We cannot support newer versions. Is it related to Open GL Ver.?
Since the GPU has a built-in CPU, it cannot be replaced with a GPU because it is a tablet.

It shouldn't have to 'install' anything, as it runs out of the folder that the files are in- I have no problem running it on my laptop with Windows 10 64-bit, however trying to save a sample causes the software to crash.

I've kept you waiting for a long time.
It is a report because it started normally.
Since the user name was Kanji, I changed it to English and tried to start it, but the status did not change and it failed to start.
After a while, I deleted all unused users to solve the SSD capacity shortage, so when I started it today, both v1.25 and v1.26 started normally and are working.

I am looking at a IIx "in the flesh" in Sydney as I write this (I should really fire it up) and I have to say WELL DONE MATE!

Did some work a few years ago on CMI30A with library archiving, user interface, and reverse-engineering of Page R and various other CMI file formats, so I have some vague idea what you went through to make this. Again, well done!

Perhaps in the future, you'd like to work on reading and importing actual Page R (and other CMI) files. This was ~10 years ago, but I know a bit about the file formats if you're interested.

High praise indeed :)

If you are on Facebook there is a usergroup devoted to QasarBeach. I can be reached there.

Any help is always very (very) welcome :)

Did you work with Graeme Renaud on the CMI30a?

(1 edit)

I had another job waiting, and I believe he showed up after I left so I didn't have much contact other than linkedin. I was around from the beginning until around the first NAMM showing or soon thereafter. Fond memories of supporting the thing remotely at the show, from Sydney, though!

drop a message to qasarbeach at the Facebook group. I’ll get immediately back to you \o/

Don't do facebook. Various reasons. Sorry. Any other options?

(2 edits)

no problem. Personal preference is email, discord? or join https://www.syntaxbomb.com/index.php and you can send me a message there (iwasadam) 


(1 edit)

send me an email to


keyboard scale function would be awesome too... dreaming of something like eleventh root of five :)

I'd love if it were possible to open Fairlight disk images directly in the future.

You just need to convert the image files with cmios9. That will allow you to directly transfer the IIx and III files to the desktop. From there you can access them :)

Please tell me I can get this working on the raspberry pi 4! I would really like the source code in order to build it myself. I'd for sure donate a good bit if I could have this running on the Pi.

currently no, but there is a pi version in the labs

work on only raspberry pi 4? or 3 too?


I would LOVE a Pi version because I could dedicate a pi4 as a "full time" Qasar machine.

This looks absolutely amazing - looking forward to trying it! I have briefly used the Series II but a Series III is my dream instrument and something that I've always wanted but could probably never afford or keep up with the maintenance costs (but if anyone has a spare one that they would like to send me, then I would happy to receive it and take good care of it!). One quick question that I'm not sure about about - can this be used as a plugin (AU or VST) in a DAW like Logic X or Live or is it purely standalone? If it is purely standalone, is there a easy(ish)way to route the audio or MIDI tracks into the DAW?

Sorry to sound rather new to all this but I have just got back into making music after a gap of about 25 years so I'm more familiar with hardware sequencers along with the Atari ST running Cubase ! and Hybrid Arts SMPTE Track so getting this Mac and leaning Logic & Live is a rather steep learning curve at the moment!

Thank you so much for developing this and good luck with the updates and future projects too.

PS - I'm sure that you're probably aware of this 30+ year old track but, with this software, I am in total agreement with the lyrics (especially the chorus!)


Brilliant find for the Shamen. I played the bugger out of this and haven't heard it in a while :)

QasarBeach is stand alone and wont integrate with outside DAWs or as a plugin.

Currently there isn't a way to sync or use MIDI to control it, but this is something I am now looking into. Particularly MIDI sync and potential control over MIDI. Let me know if there is anything you can think of that might help? :)

is there any kind of more sophisticated filter on the way? the present one looks more like shelving or something...

my dream is to use Behringer XR-18 as a multichannel interface (16 QasarBeach tracks to its mixer), on Linux. or maybe any other device to have all channels separately and mix them down in an analogue domain.

both of those are being looked into :)

I'm unable to enter number commands (for example, p1) using the azerty Magic Keyboard of my iMac (on Catalina 10.15.5). The only number that can be entered is 8, by pressing... °

This keyboard (https://www.apple.com/shop/product/MLA22LL/A/magic-keyboard-us-english?fnode=e92...) does not have a dedicated keypad. Are only keyboard with a keypad supported ?

Thanks for your help.  

(1 edit)

Sorry about that. Currently QasarBeach only supports US/Qwerty layout. I can look into adding support for you. There is a virtual number pad though. Go To Page S (settings) and enable NUMPAD:ON

All number based entry can then be done onscreen :)

Thanks a lot for your answer, I will try again with the onscreen keypad activated !

sometimes i hear nasty clicks in sound output, both on win and mac, is it a known problem?..

yes. I'm working on a fix :)

cool! can't wait :) btw, i'll probably get special pc for the QasarBeach, like in T M A 's great videos and my choice should be Linux i believe... can you make it work with ALSA directly, so i could use it without any Jack etc?..

I made a new video tutorial in german language

excellent work :) I really liked the use of MODE 2, and patching the controller in MODE 4

Glad you like it 😊

hi again ,found a glitch with filter in page 7, its behaving like a comb filter instead of a lowpass filter.

possibly. the filter is very primitive. I've not used any checking I did it all by listening to the results.

Hello Adam, about the problems some users reported in Qasarbeach crashing when setting LOOP CNTRL to "ON" on PAGE 7 ,and on PAGE E "SET LOOP" when viewing the start/end segment in(in "VIEW SEG: START END") i can confirm the following:

44100 hz 16 bit wav :

-start crashing in page E after setting loop point and when try to view the "END" segment with samples of +- 2 seconds (duration).

-crash at page 7 when set loop cntrl to "on" and pressing midi note ,and page E after setting loop point and when try to view the "END" segment  with samples of +- 3 seconds (duration).

8000 hz 16 bit wav:

-start crashing in page E after setting loop point and when try to view the "END" segment with samples of +- 10 seconds (duration).

-crash at page 7 when set loop cntrl to "on" and pressing midi note ,and page E after setting loop point and when try to view the "END" segment  with samples of +- 16 seconds (duration).

(i didn't test at 24 bit or other samplerates ,but im sure it will crash too since it seems to be related to sample size.)

windows 10, x64

I can confirm. I have the same issue with v 1.23 

all confirmed, a patch is being tested at the moment that will fix all the crash issues, it’s been sent for testing ;0

Hi Adam , i've tested the new version , it does not crash, but it messed up the "VIEW SEGMENT (START/END) in page E,doesnt display the current segment.

Btw  I have access to a 2x.

I'll drop you an email tomorrow :)

I'd be happy to help with development, especially of the sound / characteristic side, my mail is in my name!

Hi Adam, takes me back to the days, when I was a CMI operator,  its so close, stunned, keep up the good work.

If there's anything you need just let me know :)

QasarBeach crashed and closed with any wav 16bit and other file types file in Page E Waveform Edit if I set a loop and drop the start or end button. With original VC no problem . Windows 10 64bit 

these are now on the list for immediate attention. I am very interested as the .vc files are fine and the .wav are causing an issue. I’ll report my finding and fixings 😢

(1 edit)

I experienced this same problem with the latest 1.25 update, and the problem was caused when attempting to save it to vc format.

Under Windows 10 If I load a sample wav in page 2, go into page 7 and turn on loop cntrl, then play a key, the software crashes. I've tested it on two machines.  There are some posts over in the facebook group with examples.

I am still unable to run this on linux mint. It is trying to scan midi ports for a fraction of a second but still not functioning. I think this must be something to do with my linux setup being different to yours. I'm running the latest 64bit linux mint. Not sure what other dependencies are needed. Also running in wine I am unable to reduce crackling any further. I think I may have to give up now

sorry to hear about the midi. I'm running linux as a virtual machine here, so testing has not been strictly on a linux machine.

Midi is still very primitive, it's the next item on my list :)

I am now running windows 10. I will test as per above crash reports and let you know if I have the same issues

Thanks for the awesome update. I have donated for it a second time!

No problem :) Just keep me informed with any issues :)

Thats a good Idea.👍

Short explanation of QasarBeach in German language only 

I would love to be able to slave external midi gear from the Page R as well as sync the page R with an external midi-clock.

Is such feature in project pipeline too ? :)

I found Page U 

What is it for? Could you please explain how it works?

Currently it's a hidden page as it's not ready for public use.

When finished it allows you to record operations and plat them back. E.G. record a set of changes to a waveform, and then repeat those operations on other waveforms, or PAGE R, etc

Wow, interesting. Thanks

This is the best download I've made in a while.  I've been WAITING for years to have an authentic Fairlight CMI IIx user experience and this truly gives that.  Almost got a chance to jam on one but I blew it.  I am going to try and see if I can use an iPad as a sidecar for my mac and get touch screen usability.  A couple questions: any chance there could be a note priority/legato off setting when using an external keyboard?  So when a new note is hit as another note is being held, it takes priority?  

Also very glad to hear there may be the possibility of some multichannel audio (and maybe midi?) routing.  At the moment, I know there is sync record within the sampling section, but could Midi Clock sync be an option?  Would allow to sync to external hardware and sequencers, and a good way of bouncing out tracks from Page R individually and in sync.  Anyway, thanks so much!

I can certainly look into the legato suggestion for you :)

How do I run this on Linux?

Edit. I have installed 64bit linux mint and it now runs. However I am unable to use midi. The issue is that I cannot even enable midi within the program. Is this a bug or is the issue on my end? I click on the midi enable and nothing happens. If I click it too many times the program freezes up.

it's compiled on 64bit mint.

you will need opengl, openal and sdl2 installed as well :)

Thanks for that, however I still cant get midi working. You must have something on your system that I do not.

Midi is something that is still very primitive in QasarBeach. The next version will hopefully have better linux support :)

That's great. For now I have managed to get the windows version running in wine. There is a little latency and I still need to sort out some crackling in the audio but both of those are wine related issues and not specific to quasarbeach.

let me know how you get on, if there are any issues or stuff you can think of :)

Any chance you could release the source code for this?

unfortunately not. The source itself isn't too big around 30,000 lines of code. but you would need the MX2 language which is also custom created plus the editor none of which are documented

I'm sure there are many who would not mind installing a new language or a lack of documentation.

Hello Adam 

I have a big issue with the Page R on v 1.21. The timing is sloppy and slows down to zero. No more workaround with. Can't play the cookbook songs anymore. If I start Page R with v 1.20 it works well (a little timing issue you've known) My system is Windows 10. 

Is ASIO driver in the pipeline for the future? 

Best regards and keep on sampling 

Torsten /TMA 

I'll get this reverted back to the original timing for you and up a new release in a day or so :)

Wow, thanks for your fast reply. 

Is there a way to add layering different voices to play simultaneously? Keyboard mapping to split the keyboard like multi sampling? 

Sorry for asking so many questions 


V1.22 upped with fix for PAGE R

Currently no, but the original IIx did have 'Keyboards" which would allow that sort of behaviour - I'll have a think over the manual :)

The community says thank you for updating QasarBeach. I always explore new things every day and I love all I found out. The community on our Facebook group will report all bugs, crashes or problems and suggestions to help you making the project great. 

I have a problem with Velocity and Aftertouch. Can't get it work. Maybe it is my mistake? Tried it directly by routing to some parameters, tried it on function page but nothing happened. Keytime and keynumber are no problem. For example I route velocity to the volume on page 7 I see in the volume line on the right the value is always at the end of 128. The same with Aftertouch but the value is always 0! I tried it out with two different keyboards. Do you have any suggestion for me? 

Best regards 


Confirmed. I just checked and keyvol and aftertouch (from midi) are not functioning. I'll look into it :)

I would love to see ASIO compatibility with the option to use a sound card with 8 outputs, this would give some interesting routing possibilities, when it comes to tracking. [Like if you had a CMI Fairlight installed with more voice cards]

own samples in QasarBeach

That looks amazing. Thanks for sharing. I've installed Audacity also on my virtual Fairlight machine 😉

brilliant - It's how I currently get samples in QB myself. I use Amadeus On the Mac.

Here's something for you all to try. Take a sound - a vocal is a good start

goto Page 7 - the mode will be 4

change MODE: 3, AB MIX:50, B-TUNE:30

play with B-TUNE or link it to LFO 1

change MODE:2


A/B MIX: 46, B-TUNE:64

play around with SEGMENT B

Use the second with wavetables ;)


I will try this tomorrow.You mean a voice Sound Like spoken words or a choir?

Hello Adam 

I found this screenshot in your manual. Unfortunatly if I use QasarBeach I didnˋt find Cross Fade or start and endpoint visual in any page like your screenshot. Maybe my mistake by myself? 

nom you are right, this was just a visual explanation. I can add this into the app for you. it would be on Page 4 Waveform Edit

That would be great. Because it is a visual control about the important loop points

Thanks for creating this wonderful program. I bought and downloaded it. After that I have less time for other things then Qasarbeach. Fantastic to work with. I hope for more updates in the future. The community will grow. 

Best wishes 


thanks for the comments - lovely looking system you've got there with the keyboard. The only thing missing is a big white music keyboard with QasarBeach on the back. A new version (1.21) will be posted soon for you.

Thanks for your reply. Always a pleasure having direct contact to the developer. Are you working on the timing of the machine especially Page R? It is very sloppy. We did yesterday night a special "qasarbeach user video chat" for the first time on Jitsi Meet. 4 users compared their systems and helped each other to understand the workflow of the software. On my wishlist is a free configurable CC controller setting. 

Some bugs were reported: 

Timing, latency, crashes by using to many cc's (simultaneously PB and Volume fader), Page 2 issue while loading operation with a pen on a touchscreen. 

I think, after last night, we will continue the video chat meetings in the future. 

Best regards 

TMA / Torsten

Yes, the timing is a known issue. some work has already been done, but there is more work needed.

A lot of the midi stuff will be worked on next.

If you have any crash info (page you are on, what was happening), just let me know and I'll add it all to the todo lists, along with any other suggestions you can think of :)

I'll try my best to address all issues for you

do you have any .wts files I could look at? preferably 2 :)

All coming together now. 

Removed question, I discovered midi cc's control the switches and controls.

I had to check the code for that - I thought i hadn't implemented it yet!!

It was driving me crazy trying to figure out what’s modulating the first two controls and switches, I thought they’re not accessible yet.

I can use pb and mod wheel, I haven’t discovered how the switches work, but if you’re not done yet I understand why. 

Ok, I give up. How do you save a pattern or a song?

(1 edit)

Well, that was a bit convoluted but I got it! I have to say learning the Fairlight is as frustrating as it is enjoyable, it's not intuitive. Nonetheless this is an amazing piece of work, I can't wait to see what's coming! Thanks!

I felt the same the firt time i used it ,i couldn't find how to save the files,but then i read the help file on page 2, aswell as the guide and the user manual of the original fairlight,things got much clearer ,in on or two days i was much confortble .For everyone who's reading this and having the same trouble ,you have to go to page 2 "Disk control ,in the top you can see load/save option ,choose save(this activates save mode) then choose your file (in the file section)  ,then below ,you set the file name in the"NAME:" field,the command will appear ,so look to the top :D  maximum characters is 8 like in the original...then choose the file type . sound files are saved as ".VC" (voice) ,instrument ".IN"(all voices and controls) ,".CO"(voice controls,) page R composer ".RS",and you can also save the entire system ".SY"(".VC" ,".CO", ".IN" ".RS")... i like to save 2 files ".IN" and ".RS" and when you want to load my project ,i load both files(page 2) since you need both the intruments and the page R sequence,everything like the original fairlight. 

Thanks - the Fairlight has it's own way of doing things and I tried my best to replicate it. You can see why 'engineers' were highly sought after. You can also save wav files by using the 'wa' option.

Yes, I do know, I used a Synclavier from '89-'98 and the early days were painful. We're so spoiled using all these great apps and daws. I've been reading the original manuals for the IIX and they do help understand how the system works, and it is pretty basic.

My issue now is I'm not able to edit notes once they are in the pattern. I click on a note and get it's parameters in the left window, but any input I make is ignored. I've tried to change pitch, vel, panning to no avail. Is there something I'm missing? 

Ahh, I need to have Record armed to be able to edit notes on R page. 

Hello, found some problems,when loading 8-bit wavs it crashes Qasarbeach, 16 bit  and 24 bit works fine.Also in page 2 the "bits" will always display 16 bit regardless if a select a 8 , or 24 bit wav.

Thank you.

can you give me a download to the samples that don't work? I'll debug them for you :)

sure ,here it is:

Thanks for this - very useful. all above now fixed. will be included in the next release :)

thank you :)

Hello ,i love qasarBeach  ,i'm reading the user manual to learn more about the fairlight operations,today i was testing page 5 ,in the original there is a (fourier) "ANALIZE" command,that allows to reconstruct a sample by generating harmonics for the segments.Is this being worked on? Also on Page A , will it be possible to record michrophone or stereo mix? thank you so much !

good questions and both are being worked on :)

thank you :)
