"Isn't it a disadvantage of such all-in-one-daws that all music produced
with it sounds pretty similar to each other, everybody uses the same
samples and plugins. An creative advantage of modular linuxaudio could
be that you've a high level of creativity and uniqueness in your music."
I do not agree with the premise that because everybody uses the same plugins it all sounds similar. As for samples, all-in-one DAW does not force you to use any samples, rarely does a DAW come with decent samples anyway. And same plugins can be used in a very different way.
