I’ve gotten into virtual pipe organs - sound samples of real organ pipes loaded together with a suitable computer interface, which conveniently resembles an organ console. Hauptwerk, by Crumhorn Labs, is easily the most sophisticated although I have experimented with others. The software was created by Martin Dyde and the included instrument is based on St. Anne’s Moseley in the U.K.
The name of the game is CPU speed and memory - lots of it. I had some success with the organ that ships with the Hauptwerk software on my existing computer hardware. Other sampled organs, however, gave me a bit of a problem. The “crackles” I call them. This happens when the combination of CPU speed and memory in your machine doesn’t possess the required computational power to handle large instruments.
Consequently, I decided to get an Intel Duo Core machine from Dell which had 2 Gigs of memory, a respectable CPU speed and ran on Vista. I worked with that for a while. However, it quickly became apparent that even that setup was not able to keep up with the extraordinary demands of large organs with huge numbers of pipes all speaking simultaneously.
I finally ordered up yet another a new computer that was on the bleeding edge of raw CPU power. Essentially, I got a “gaming” computer which had quad core processors running at 3 ghz along with 4 Gigs of memory. I could add an additional 4 Gigs memory for a total of 8 Gigs; however, it seems to work fine so far without the additional head room. The computer was specially built by Cyperpower pc. Additionally, I ordered Windows XP 64-bit edition which enabled me to install the additional memory. Also, I didn’t want the additional demands of the “Vista” OS interfering with my virtual organ. The problem I find with the Windows platform in general is that it isn’t particularly “quiet”. It always wants to do something. I had to tweak it to keep it from doing things other than load the organ – and nothing else! In other words, you need to create a “dedicated” machine that doesn’t run anything else, especially anti-virus software. (Just keep your machine off of the internet after you get it going; that’s where all the viruses come from anyway).
Probably the most demanding of the virtual organs that I have obtained so far is the Mt. Carmel Skinner organ which is available from Milan Digital Audio. I used that organ as the “acid test” to make sure my latest CPU configuration was delivering the music properly. No problem.
My only complaint at this point is that I need a three manual console to properly play the Mt. Carmel organ. Currently, I am practicing at home on a Rodgers Model 530 two-manual digital organ. Since this organ has MIDI capability, I only needed to put a MIDI/Sound card in my new computer to “complete the circuit”. The soundcard I bought was an M-Audio Audiophile 2496 PCI Audio Interface. Works fine.
At my church, I would like to try using a virtual organ to play certain types of music repertoire that wouldn’t otherwise sound effective on my 1971 Austin pipe organ which is a smallish American-classic instrument. However, I don’t think I would attempt to use the virtual organ to accompany the congregation as the real pipe organ is eminently suited for that purpose because it was voiced to the room. But for certain pieces, the incredible variety of sounds available from virtual samples would certainly allow for richer choices in registration.
If you care to try creating your own virtual organs, I suggest using the free software known as “My Organ” availalble at kloria.com. That software along with Hauptwerk version 1 compatible organ samples should get you started.
