Information and requirements for the Hauptwerk version

What is Hauptwerk?
Hauptwerk is an application which is available since the beginning of 2003. The main goal is to make it possible to play a real existing instrument (e.g. organ, clavichord) in the livingroom.

What do you need?
Besides the application Hauptwerk you need the folowing things in order to play:
- a Sampleset (containing the sounds and thhe definition of the instrument)
- a Computer with a 600Mhz processor (or higher) with a minimal of 1,25 Gb internal memory (depending on the used sample set and the organ definition file *)
- a Midi-interface for the Computer (available on most soundcards using a interface cable available in most musical hardware stores)
- an Electronic organ with a midi-out
- a Midi cable

* Organ definition files can be changed easily. Small changes will be made for free till 2 weeks after delivery.

How is a sampleset been made?
- Per stop a recording is made of every keyy (Result: a large set of raw samples)
- Per sample the noise of the organ blower and any other unwanted sources is been filtered away (Result: a set of samples free of noise)
- If necessary detuned samples are being tuuned (Result: een set of tuned samples free of noise)
- a Organdefinition is made in which all saamples (pipes) are connected to stops, and stop to manuals

How does this become playable?
Make a connection between the midi-out of the electronic organand the midi-in of the midi-interface on the computer using the midi cable. Then start the application Hauptwerk, load a sampleset, and off you go, ready to play!

Pulling stops while playing
Most of the common digital organs today are sending a midi signal at pulling a stop knob. In Hauptwerk you can connect each stop of the sampleset with a stop knob of the electronic organ. It might be usefull to make stickers or anything else because the stoplabels on the electronic organ will differ from the stops of the sampleset.

Older digital organs may not send midi signals while pulling stops. In that case you have use the computer keyboard or mouse or even a touchscreen in order pull stops.

Available samplesets
As shown on the website of Hauptwerk ( under 'Third Party Vendors' there are already a large number of historical instruments available. Listen to the demo files to convince yourself.

Advantages of Hauptwerk

Of course you're able the hear that you're not playing a real pipeorgan. But still there are a few advantages compared to the common electronic pipeorgans:
- Every pipe has been sampled. When you play a chromatical scale with e.g. a trumpet stop on a regular organ you can hear that only one or just a few samples has been used. Only the pitch differs and that's all there is.
- The natural reverb is captured within the samples. This makes the organ sounding very realistic and natural. (Of course there are churches with beautifull and less beuatifull reverbs.)
- Instead of buying a new organ you add a new organ to your livingroom. While having more than one sampleset you choose the sampleset that is appropriate for the piece to play. Thats really refreshing!
- Not mentioned the price: on this moment you can purchase a sampleset between 50 and 360 euro. You can't buy a new Allen or Rogers for this sum of money! Allright, it might be nessecary to upgrade your computer after purchasing your first sampleset.
- Everything you play can be recorded immediately (like the mp3 demo of Rinck on this site). (Make yourself a cd for your family so they can enjoy organ even if you're out)
- If you doesn't have an electronic organ, you can also play your organ midi-files through Hauptwerk. This will definitely sounds better than the standard midi sounds of the computer!
