Soft synths will only produce audio clips when they are frozen. You can freeze them then bounce them for permanent audio clips. Once this is done you can actually remove the soft synth without affecting the audio clip it produced.
Just for clarification, can produce audio clips from Soft Synths several ways besides just freezing them. Also, if you freeze the track, it IS a permanent audio clip already and doesn't require re-bouncing. If you want the frozen audio to start at zero, simply Slip Edit the midi clip first to start at zero then you can Freeze it and it will be audio. You can delete the frozen tracks Synth and keep the frozen tracks Audi without re-bouncing by un-ticking 'delete associated tracks'. I prefer to disconnect the Synth just in case I wish to change something, re-do or add to.
One of the newer ways to turn Soft Synths to audio is by arming the Record button on the Synth audio track, then hitting the main record button. (realtime records it). You can then mute the midi track with the Synth still connected or disconnect or the Synth from the Synth rack. This keeps all your Synths and Patches handy while freeing up your resources.
Another method to turn Soft Synths to audio which I prefer is Bounce to Track. Simply highlight the Midi track and Synth audio track then hit Bounce to Track (Tracks menu) source category 'Tracks' and either Bounce to a new track or to the Synth audio track or make and name a new one before the Bounce to track step and point it there. I like to do this and like I said Disconnect the Synth from the Synth Rack so as to be able to reconnect to change, add more, or multi-track bounce (drums for example) at a later time. I've been burned by Un-freeze in the past and have lost all synth patches and info, so now I disconnect and reconnect.
Of couse you can export and reimport, but why do that when Bounce to Track Saves you that Step and the step of having to point the export location. Just as a mention though.
Anyways, just trying to clarify and be informative and helpful in the spirit of the forum. ✌️
