64-Bit vs 32-bit DAWs

When using Spectrasonics instruments within a DAW, the latest versions require a 64-bit DAW.

Starting with MacOS 10.15 Catalina, all applications will only work in 64-bit.

If you're using MacOS 10.14 Mojave or earlier, we suggest that you run it as a 64-bit application. This will allow you to access any RAM you have in excess of 4GB. 32-bit hosts can only access a little more than 3GB of Virtual Memory.

Most current DAWs are 64-bit compatible. To run your host in 64 bit mode on an older Mac operating system, please locate the icon in your applications folder for your host. Right click (or control + click) the icon and then Get Info. In the window that opens, please uncheck "Open in 32-bit mode"

32bit mode

Reopen your host and it will scan for 64 bit instruments.

Although it is not recommended, if you must use a 32bit DAW you will need to install an older version of your instrument:
