Well, maybe not for individual programs, but for operating systems it's important.
* EP looks at Vista, ME, and Mac OS 10.0
Yep, that is the case.
I just got some generic one, so recommendations are nice.
Hm...for complete single-file soundfonts I highly recommend SGM v2.01, Titanic GS v1.2, and GM Thai Mix. They are very large (>100-200MB), however.
As far as multi-file ones are concerned, Fluid R3 is my pick. THFont is also common, especially amongst some of the musicians here.
For good miniature (<50MB) ones stick with Musica Theora or Chaos Bank.
There are also even smaller ones (1-8MB) if space is a priority, namely a few from Creative (which were used with its sound cards).
Lastly, Scct12 (~4MB) is the closest approximation of the MSFT and AAPL default MIDI synth that I know of...sounds just as bad! :V
Well, I test it in VMs too. Just remember to set the RAM to 1GB or so and turn on hyper-virtualization in the BIOS for best performance.
Already do both (usually put 2GB RAM, 2 emulated cores, and Intel VT-x).
