I already installed several free VSTs and todays were looking for free strings.
All of the VSTs I tried fail to be loaded by the plugin manager. As an example, take https://www.dskmusic.com/dsk-strings/
You use 64bit Ardour, but the plugin is 32bit β the Log says βFile type: i386 (32-bit)β.
64bit Ardour only loads 64bit VSTs.

Short of running 32bit Ardour (which will only load 32bit but not 64 bit VSTs), you could check if the vendor provides a 64bit version. Alternatively some plugin-bridges (e.g. plogue) can work around this and bridge CPU architectures.
