KordsKontrol is at the moment still a beta software.
It is working perfectly well for me, with my computers and my controllers, but since it is intended to be used with many different controllers, from different brands, to be a multi-system software (Windows, MacOS, Linux), and because one of its use case is a live use, on stage, it is not acceptable from my point of view that any bug are left in it, and so, I consider it still needs to be intensively tested by a large amount of user before releasing officially a commercial grade version.
KordsKontrol team is basically 1 people (me!), and I am not a professional software developer.
I develop it on on my “spare time” – the spare time that your have when you have a full time job, a young kid and an house to refurbish 🙂
I am (and will always be) offering free Windows PC, Mac OS and Linux Debian Demo versions of KordsKontrol , with all the functionalities, except that saving chords progressions, and loading and saving Arpeggios are disabled. The application will also shut down after 30 minutes, but you can run it again as many time as you wish. Demo versions are in fact full version of the software, but with some functionalities disabled if you don’t own a Full Commercial License key.
Thus, anyone can test it, make sure that it works properly on their system, and let me know any potential issue encountered.
The commercial policy for KordsKontrol is to offer an affordable Full Commercial License file (the price is 50€) to unlock the features that are disabled in the Demo version.
Asking for a contribution to get a Full Commercial License is required in order to support financing the development of the project:
- Let me buy more controllers to ensure compatibility in detail, and adapt what needs to be adapted to have, for all the controllers, a satisfactory user experience
- Invest in Marketing, advertising, to allow this project to have a better readiness and visibility
- Consider partnership with software solutions providers to, for example, integrate in the installer the automatic generation of the Virtual MIDI ports needed in some cases
- Work on KordsKontrol remote solution (see the related page for more details)
- Finance the Website domain, implement a better solution for purchasing the license
- …
KordsKontrol represents more than 20 000 lines of codes written during more than a cumulative 1000 hours of work over the past decade, mostly done late at night, with the obsession of delivering a stable, powerful, easy to use and musical tool for the musicians community. It features some unique capabilities, and I hope anyone will understand that I cannot provide it completely for free if I want to be able to continue to support its development actively.
If you want to get a Full Commercial License key, it is already possible still, and there are 2 ways to get it.
First way: Through the Beta phase support program
I would be more than happy to offer for free a Full Commercial License of KordsKontrol to anyone that could support me during the present Beta phase:
- By writing a review online (positive or negative, as far as honest and constructive)
- By posting videos of your use case or compositions with it
- By lending me (if you live in France) one of the controllers I dont’ own to let me check easily if it works as intended (see Compatibility page for more details)
- For any kind of support (artwork, marketing, if you are a professional Java and MIDI software developer, distribution…)
Please do not not hesitate to contact me for more details
Second way: by purchasing already a Full commercial License
If you simply want to purchase a license during the Beta phase (because you have tested the demo and already want to access to the full version, or because you want to support the project), please simply use the PayPal link provided bellow to donate 50€. Do not forget to mention you complete Name, so that the license, that is nominative, will be customised just for you.

A few words on KordsKontrol commercial policy
Full Commercial Licenses are provided in the form of a Commercial License Key personal nominative file that unlock the functionalities of the Demo version into a Full version
The personal license file generation system is already in place
The Commercial License Key is sold via a simple Paypal system. Once payment is received, you will be provided by email a personal nominative Full Commercial License key file.
Any purchase will be definitive; no reimbursement shall be provided because I don’t have the possibility to disactivate any license (I will not put in place any License server of any equivalent dynamic licensing solution). In all cases, the Demo version will have to be installed and tested extensively first before any purchase.
This Full Commercial License key will grant you a personal, non-transferable, non-sublicensable, limited, and non-exclusive right to use the KordsKontrol software without the Demo limitations on several computers but on any one computer at any one time, for use by a single concurrent user, and solely provided that you adhere to all the terms and conditions of the application End User License Agreement (EULA).
KORDSKONTROL End User License Agreement
All the music created with KordsKontrol will -for sure- be yours totally, and you can use it the way you like, including for commercial purposes.
This License Key is strictly personal and non-transferable; it is not allowed to share this License Key with anyone.
If updated versions (2x) are released in the future (added minor functionalities, bug fixes, …), or if the application becomes compatible with others MIDI controllers, it will not be required to Purchase the License again.
In case of major upgrade in the future (version 3.x) , the access to the Free Demo version of the update will (and will always) remain free, but it could be required to Purchase a new License Key to unlock its limitations if the upgrade is significant enough (equivalent in terms of features and work to the update done between version 1 and 2). In any case, upgrade will be cheaper than Full license cost (maybe 20€ for a major upgrade). It is a policy used by most of software company today, and I might have to put this in place to finance the development of a potential future major 3.x update. For sure, anyone that purchase a license just before a major update will get the update for free.
If you are a company and want to use some of KordsKontrol features, contact me for potential licensing solutions.
