Thank you Bianca for your input, but probably before speaking it is useful
to know who you are facing.
Aside from being a programmer, I have been using Cubase and related MIDI since 1988, basically since it came out or around then,
think about it, it ran on ATARI computers; clearly it was only MIDI, it didn't have audio :-)
The problem with these libraries is that they have poor samples, low quality in my opinion; based on how they are advertised, they seem like the top in terms of digital recording, but for me the quality is quite poor.
I use the parameters and so on, but it is the timbral quality that leaves me dissatisfied: bad sound, and bad articulations.
The sustained notes are loops; the attacks, releases, and other related envelopes are made via software, therefore artificial; add a bad microphone recording to that, and there you have it—for me, they aren't worth all the money these software houses ask for.
I didn't start playing with sound libraries yesterday; I have been producing music for more than 25 years; add to that that I studied electronic engineering, acoustics, and programming :-)
But it is probably just my experience; if you find them irresistible, keep using them, I am not here to change your mind,
in fact, I use them too because I don't have an orchestra at my disposal, but as I said, I try to mask them, and most of the time I pretend nothing is wrong, meaning I don't give them chronic attention.
The problem remains mine; perhaps I demand too much from simple digital samples, and to think they charge you an arm and a leg for them :-)
