Hardware and software requirements
The organ sample sets are hosted within Hauptwerk™ virtual pipe organ software, available for both PC and Mac computers from Milan Digital Audio, found at http://www.hauptwerk.com on the Internet. Hauptwerk™ functions with both currently available 32-bit and 64-bit operating systems. Hauptwerk™ Advanced Edition is recommended. A high-performance computer is required to experience full, flawless and convenient operation of this sample set.
RAM and number of loadable stops
Since Hauptwerk™ loads the sample data into the computer’s random access memory (RAM) – and does not stream data from the hard disk – the amount of RAM determines the number of stops you can load for playing at a given time. The theoretical RAM limitation, per program instance is 4 GB in 32-bit operating systems; loading all stops of the organ requires a 64-bit operating system, capable of handling at least 64 GB of RAM. Regardless of operating system, please make sure you are using more than 4 GB of RAM.
Hauptwerk™ allows you to load the sample set with independent options for each available stop, allowing you to trade off the number of loadable stops with varying degrees of realism (you can, for example, choose to load less than the full complement of release samples). Loading all of the stops in their most complete multi-looped versions and with full release samples will consume much more RAM than loading them with, say, single looped data and/or truncated release tails.
Please refer to the Hauptwerk™ User’s Manual for a complete description of how to maximize performance with these features.

CPU and Polyphony
It is essential that your computer has a high-performance CPU in order to experience full polyphony without dropouts or audio distortion. A high polyphony capability is required when many stops are drawn and many notes played together.
Note: Polyphony is defined as the number of stops being selected, times the number of notes held per stop, including the duration release tails to sound, at any given time.
A series of fast staccato chords in Tutti will stress your computer the most, because the initial release tails will continue to sound as additional staccato chords are being played. For the most flawless operation, we recommend the use of a 4-core CPU or better, equipped with the most RAM that you can afford. As your CPU power increases, you can achieve more polyphony.
Please refer to the Hauptwerk™ User’s Manual for a complete description of how to achieve maximum polyphony with your computer.
