Just reworked a little my first piece “Melting Point” written with LMMS. First time used the sound compressor. So, what is compressor? A compressor is a sound processor that starts to work when the sound level is greater that a threshold, i.e. it will decrease the sound starting from this point, and at the same time leaving the quiet sound unaffected… so, I am trying to understand its real usefulness… i.e. when to use it and when not.
