Surely one day , but ... when ?

Samplitude Music Studio has a version 64 bits and a version 32 bits

 

Generally , .32 bits plugin are incompatible in a 64 bits hots , and 64 bits plugin are incompatible in a 32 bits host .

So if you migrate in a 64 bits host , you could run your 64 bits plugin , but you couldn t run your old 32 bits plugin

 

In fact , it s more one general problem of the Operating Systems ( Windows , MacOs, Linux , etc )

 

If you want to use some 64 bits VST inside a 32 host program , you may use a bridge to convert your 32 bits plugins in 64 bits plugins , and your 64 bits plugins an 32 bits plugins

There is the instance of JBridge ( actual cost 15 $) :

An another possibility is to run in paralelle Magic Music Maker and an anothe midi host .64 bits .

a) You create the wav tracks in Magix music maker ( easier than in the other daws )

b) you create a midi track with midi notes inside Magix music maker with no instrument , but you route this with a virtual port , or IPC ( some of them re free , some of them are low cost )

c) you create a track in your 64 bits daw with a 64 bit plufin a,d you sets up it to receive midi notes by the virtual port or IPC

So when midi notes will be played inside magix music maker , your other DAW will receive the midi notes and will generate the sound via the VSTi plugin

d) if you are glad of the result , you drag and drop the wav generated sound from your DAW to Magix Music Maker

e) if you don t need to change your midi melody or chord , you may delete your midi track

J bridge only works with one of my plugins. I will try the second thing you mentioned.
