Hi Fran.
Sound parameters Meaning
Attack Attack time. This is the time during which the
sound goes from zero (at the moment when
you strike a key) to it’s maximum level.
Yes but your only looking at the AMP there. ADSR can control LFO, Filters, EG Pitch, EG Level, Modulation, and the AMP. It all depends on what way you route the modulators.
[quote]Seems that Korg uses the Low freq oscillator..as a vibrato to me
You can do that too, but you can also modulate the pitch or any element of the sound with a large array of functions. There's nothing really locked down to a specific way of working on a KORG. The engine is extremely flexible so you can get really imaginative and create some very unique sounds.
Also the LFO has an array of different wavesapes as I mentioned above, not just a Sine wave which you would use for a Vibrato. You can do all sort of crazy stuff.
You really have to think outside the box when working with a KORG because it's so flexible. It's a very deep engine.
