George Gershwin wrote Rhapsody in Blue after 16 years of learning; J. S. Bach composed his first famous fugues after 18 years of study. Would you buy a composing tool if you knew that you will loose it in 10 years? No? How about your computer? Apple changed its CPU every 10 years; it happened in 1984, in 1994 and in 2004. Each time apps that might have taken years to master were lost. Software companies love to fret how their products work as well or better than dedicated hardware. Not one ever added, "except the metal running it will be gone in 10 years at most."
Great composers usually use the same, well-learned composing tool throughout their lifetime. Bach had a clavichord. Gerswhin used a piano. Today the tool might be a bunch of programs, and sound libraries on a computer. How do you preserve this for a lifetime? By loading it into a virtualization program.
For those who never heard of these, a virtualization program like VMware’s Workstation (http://www NULL.vmware NULL.com/products/workstation/overview NULL.html) or Oracle’s VirtualBox (http://www NULL.virtualbox NULL.org/wiki/Screenshots) runs like a computer inside your computer. You can install and run operating system(s) and program(s) into its window, which can be enlarged to full monitor size. The program saves its whole virtual enchilada, called "virtual machine" (VM, in short) to hard disk as one file; like a giant synthesizer patch. Open this VM file on any new computer that has a matching virtualization program and bingo, your whole work toolset springs back to life as it was on the old computer. (Some programs, plugins or sound libraries may require reauthorizing on the new computer, but this is rather minor compared to having to reinstall everything from scratch.) So you can take your tools on a vacation on a laptop, or migrate them to a new computer, switch them from PC to Mac or Linux or vice versa – you just became independent from your computer’s lifespan. Welcome to Eternal File…
The cost? Time, mostly. You’ll need to recreate your composing environment in a virtual machine – once. Some programs claim they can convert your existing computer setup to a VM, but I have to see one useable result yet. Most of these conversion utilities are free though. Also, a music DAW program has slightly lower performance in aVM than on the host operating system (OS). On my i7 PC overclocked to 4.36 GHz, the standard Ableton test file (http://forum NULL.ableton NULL.com/viewtopic NULL.php?f=1&t=111880&start=0) used 13% CPU capacity in a VMware virtual machine, versus 10% on the host Windows 7. (See table below.) Without overclocking, the same file required 14% on the host Windows 7, so a bit of overclocking can give you more CPU boost than what virtualizing takes away.
Bottom line: if you’ll live just another 40 years (a very conservative estimate) and you buy a new computer ever 2 years, you’d have to reinstall (er, "migrate") and relink all your working apps and plugins and sound libraries and what-have-you 20 more times. Given that relinking the files of a single moved Ableton sampler library alone may take 5000+ hours (http://forum NULL.ableton NULL.com/viewtopic NULL.php?f=1&t=164225) as I discovered at my own detriment, 20 computer migrations can add up to half a lifetime wasted. If Bach had to work this way, he’d have completed a total of 5 songs in his life. On the other hand, if you virtualize your work tools just once, you are set…
Notes: in spite of its numerous good sides, virtualization (in its present form) has shown some shortcomings too. On Windows 7, the OSX VM (http://www NULL.redmondpie NULL.com/how-to-install-os-x-snow-leopard-in-vmware-windows-7-9140301/) offered no screen resizing, only cropping of the OSX desktop. On OSX only 6GB of RAM from the 18 Gigs present were recognized and OSX misread CPU speed as well. A boot OSX allowed only OSX server (not plain $29 OSX) in VM. Windows XP x64 (64-bit) touted as the best potentional host OS of all, crashed with every 64-bit VM in fact. Finally, all current virtualization programs lack support for FireWire and certain PCI cards. The discussion on composing tool longevity continues on several places, between them this Motifator thread (http://www NULL.motifator NULL.com/index NULL.php/forum/viewthread/455663/P40/), where new ideas such as "synth block design" and "recording black box" are also introduced.
