Long ago many people used fxmax teleport in windows xp, vista and 7, 32-bit only....
Large Sample libraries was Not possible because the 4GB "3.7GB" limit of 32-Bit OS & software,
You could install 64-Bit XP, Vista or 7 but audio software was 32-Bit.
The main pc was usually the more powerful tower, in that time laptops were very limited, dual core.
Usually laptop was helper, towers were q6600 or better.
Most plugins like faster cores than many but slower cores in audio,
Specially Protools 12.7 softube modular, some pspaudioware, etc...
With today crazy fast Apple i9 MacBookPro lines have blurred.
Also USB soundcards was Not possible in the past because the limited CPU power, impossible in a Pentium4 1-core,
most people had Digi001 pci or similar pci soundcard, RME, Lynx Studio, etc... firewire was on the edge, but today Focusrite Clarett USB have professional quality at a decent price impossible a few years back. Digidesign 888/24 AD/DA was $3000usd. 48khz and requires Mix Farm pci cards $$$.
Technology has evolved very much in 10 years.
Pro studios were Not using CPU only, were using DSP cards like Creamware Scope, Protools Mix, UAD, Yamaha DSP factory DS2416, TC Powercore, Korg Oasys, and others... Or digital mixers.
Powerful & fast = main.
Slower = helper.
Mac world was another story... Most audio software was designed for 32-Bit G4 cpus with OS9.2, OSX Tiger 10.4 or OSX 10.5 Leopard, almost none for 64-bit G5 optimized.
The 2005 Quad G5 was very powerful, as good or more as 2007 Q6600, but changed from PCI to PCIe, PCI soundcards like Digi001 were abandoned, had water cooling leaks, etc...
G5 has 90nm, intel q6600 had 65nm.
Watercooling 2.5GHz was required.
There was a previous golden era, the Atari ST midi studio with Steinberg Cubase or C-Labs Notator, everything in Hardware, samplers, mixers, everything...
Commodore had very limited Midi SW.
Old music can be done with new HW, there are youtube tutorials...
Sounds very similar...
