Powermix & TDM switcher?
 

I’m still rocking Pro Tools 4. On my 4.1 installation cd there is a PT24 installer and an AMIII/Powermix installer. It also has a separate, optional extension for Powermix.

When I install the TDM/d24/PT24 version along with the Powermix extension, holding down N upon launching PT doesn’t show me the Powermix mode. It’s only when I install the actual AMIII/Powermix version that it shows up.

I know it’s been like nearly 25 years, but does anyone remember being able to switch between the normal d24 version and the Powermix version? Not sure they can coexist on the same machine.
