The popular “Save as VST” softwares (Synthedit and Synthmaker) are Windows only. When it comes to Mac OS X, the number of freeware plugins is very low, compared to the Windows world. When you consider the processing power of high-quality PC’s and Mac’s, it’s no surprise that some plugins can push the boundaries further than a physical instrument. Many piano VST’s are thought to sound more realistic than the piano engines found in keyboard workstations, etc. Arturia really stepped up their game with the Stage-73 in my opinion. And in case you missed it - they're all free.
Presented in our own plug-in, they are easy to use, and compatible with any DAW. An infinite series of free software instruments, made by musicians and sampling experts in London, for anyone, anywhere.
