Incredible Realism

You literally won't believe you're not sitting at a real mechanic organ - that's how incredible our HAUPTWERK keyboards truly feel.
How does that work? We're the only manufacturer using variable electromagnets to generate the desired counterforce of each key instead of common permanent magnets!

COUPLERS

KEYCHANGE manuals can be freely coupled. With the new Mixtuur version, this is even visibly "mechanical"!

SLACK AT TOP OF KEY STROKE

Before a mechanical tracker action "engages", the key moves through an area without any counterforce. You can fine-tune this feature to an accuracy of 0.1 mm.

CLOSING THE VALVE

The valve opens at the breakaway point and closes with an equally palpable sensation on the key's return stroke.

FRICTION

An action without friction feels unpleasantly sterile. Our software therefore accounts for this factor.

SLACK AT TOP OF KEY STROKE

Before a mechanical tracker action engages, there is a certain amount of free play. You can precisely adjust this to 0.1mm.

COUPLERS

KEYCHANGE manuals can be coupled as required - including multiple pressure points.

Was this the missing piece? Absolutely! Exquisite key action: Finally, the goal is no longer to ignore the peculiar conventional "magnetic pressure point," but rather to feel the material and movement.

Regardless of the digital organ's sound quality, this 'action' delivers an unparalleled playing experience. Yes, this was truly the missing piece!

I had the opportunity to test KEYCHANGE KEYBOARDS in advance, and they impressed me from the start. The playing feel is extremely realistic and can be adapted to any conceivable organ.

You truly feel almost as if playing a real instrument – no comparison to other electronic keyboards I have tried so far. A significant step forward in digital organ playing!

Bastian Fuchs

Organist at Mariahilf Church in Munich/Au

Finally, a true breakthrough in the world of electronic organs! Previously, one would practice twice: once on the electronic organ and then again in the church or concert hall.

With KEYCHANGE, you can prepare for any tracker action even at home: Infinite adjustment possibilities open up a new dimension for electronic organs, which has been distinctly lacking until now!

FAQ

Below you will find answers to the most frequently asked questions about KEYCHANGE KEYBOARDS.
If we have missed anything, please give us a call or send us an e-mail!

Do I need to be a tech pro to adjust my KEYCHANGE manuals?

No! Using KeyControl is just as simple as selecting a HAUPTWERK sample set: all playing characteristics can be adjusted intuitively using the sliders.

Can I set the manuals independently of each other?

Yes, you can either set all manuals simultaneously or adjust each manual individually.

How much power do KEYCHANGE manuals consume?

The power consumption with an average key weight of 120g is around 120 watts.

This corresponds to the consumption of two 60W light bulbs - and therefore significantly less than the PC in a HAUPTWERK organ.

How reliable is the technology? Is there a guarantee?

We offer a 5-year warranty on all parts except keycaps.

We develop all the electronics and software in-house, manufacture the mechanics and keys ourselves and test every keyboard before delivery. This is the only way we can guarantee the consistently high quality and reliability of our products.

All mechanical and electronic components have been thoroughly tested by various organists under continuous operation.

How do I get help if the technology fails?

Just one call is all it takes , and we’ll connect you with the engineer in charge—if the problem can’t be resolved remotely, we’ll of course either come by as soon as possible, send an authorized technician, or replace the keyboard.

This service is free of charge for you!

What technical requirements does my organ have to meet?

In principle, one MIDI input is sufficient. This applies, for example, to sacred organs with a MIDI option.

To use our real-time interface, you need a Windows PC with a network connection (Ethernet) and a synthesizer of your choice (e.g. HAUPTWERK). On laptops without a network connection, this can usually be can usually be retrofitted!

Can I retrofit KEYCHANGE manuals into my existing console?

We manufacture to BDO dimensions as standard and are compatible with most organ consoles.

Please let us know the exact dimensions of your old keyboards before placing your order so we're able to provide you with appropriate adapters if necessary!

What delivery times should I expect?

The average delivery time is approximately 8-12 weeks.

In some cases, there may be variations—for example, if you have particularly complex design requests or a large order volume. But it’s just as likely that your keyboards will be ready to ship in as little as 4 weeks!
