The most natural, human-like, vibrato is what you should aim for.My initial question is the following: how can I produce a "vibratto" using only the PSG? I was amazed when I heard MATRA's productions music and sound featuring only PSG support. I guess that I have to combine envelopes and change simultaneously the frequency. Am I right?
To do this, make sure your vibrato routines have:
an attack
an offset to control the vibrato-output ( so, like:.. [+0 +1 +2 +3 +4 +3 +2 +1] )
random fluctuations to the amplitude of the vibrato
random fluctuations to the speed/freq of the vibrato
and for the real freaks:
random fluctuations to the attack of the vibrato
velocity controlling the vibrato depth
velocity controlling the vibrato attack
